    <para>
	This project has been started by Martin Wilz in summer 1998
	and has been developed and improved by him an some other
	people. In November 1999 Thomas Eschenbacher has started
	to fix some little bugs here and there and stepped into
	the source code of the program deeper and deeper. Up to
	today he has extended, rewritten or revised nearly every
	component of the program and spent much time on improving it.

    <para>
    	&kapp; has an own homepage under
    	<ulink url="http://kwave.sourceforge.net/">
	http://kwave.sourceforge.net/</ulink>. Here you can
	find further informations about the project, as well as
	informations about current stable and up-to-date development
	versions.
    </para>

    <warning><para>
	Maybe older versions of &kapp; are currently included in some
	current linux distributions. We recommend not to use &kapp; versions
	0.29 and older.
	And please don't get confused by the version number,
	"0.29" should actually mean "0.2.9" and was not consistent. The
	current version numbering starts from 0.5.
    </para></warning>

    <para>
	If you want to get a &kapp; release, you should download a .tar.gz
	archive with the source code of a stable or a development version
	from the homepage above (or check it out from CVS) and compile it
	on your own. Don't be afraid, this should be quite simple even if
	you are not a programmer. If you need a rpm package, please let us
	know or build it on your own like described in the following
	chapters.

	If you are runnig a system with RPM support, the preferred way to
	install &kapp; on your system will be the creation of a nice RPM
	package. First you should get the current source of &kapp;, either
	as a tar.gz archive from the &kapp; download page or
	check out an up-to-date copy via
	<link linkend="cvs-repository">anonymous CVS</link> (like described in

	<link linkend="building_rpm_from_cvs">next</link> chapter.

	If you have downloaded a tar-gz archives of &kapp;,
	create and install the RPMs just by doing the following steps

	have built the package and might be something like
	<literal>i386</literal>, <literal>i586</literal>,

	This chapter should give a short introduction about the basics of

	you can ask at the &kapp; mailing list or consult some further

    <para>
	First of all, one must know that the
	world is <emphasis>analogue</emphasis> - but computers work
	<emphasis>digitally</emphasis>. So there are
	several ways to convert analogue audio to digital audio and back
	again. As the way from digital to analogue normally is the
	reversion of the way from analogue to digital, we only describe
	the way from analogue to digital.

    <para>Conversion from sound to bits</para>

    <para>
	Before continuing, analogue audio has to be transformed
	into electronic signals in order to find it's way into a computer.
	One common way to do this is by using a microphone and an
	amplifier. This combination gets sound (changes of air pressure) at
	it's input and a voltage at it's output. Higher
	amplitude of the pressure changes will be represented by higher voltages
	at the amplifier's output. This output is also called a
	<emphasis>'signal'</emphasis>. Instead of a microphone you can of course
	also imagine other sources of audio. And the "amplifier" can be the one
	that is integrated into your sound card, where you normally can't see it.

    </para>
    <para>Conversion to electronic signal</para>

    <para>
	At this stage, the electrical signal has three limitations that one should
	keep in mind:
	<orderedlist>
	    <listitem><para>
		The <emphasis>amplitude</emphasis> (volume) is limited to
		some maximum level.
		This is a consequence of the electronic (amplifiers) that are
		only able to handle voltages within some specific range.
		That's no problem as long as sounds are not too loud. In that
		case the signal would be <emphasis>clipped</emphasis>, which
		means that the electrical signal will run against it's margins
		and the result will be disturbed.
	    </para></listitem>
	    <listitem><para>
		The <emphasis>frequency range</emphasis> is also limited.
		Due to the mechanical
		constrains of microphones and the limited frequency range of
		amplifiers, a signal's frequency range is limited. There
		are no hard borders besides which the sound abruptely disappears,
		but below some low and above some higher frequency the amplitude
		of the signal starts to decrease more and more. The existance of
		a maximum frequency can be easily understood as a limited speed
		of the electrical signal to rise and fall. By using high quality
		amplifiers and microphones, the limits can be spread into ranges
		where the human ear is no longer able to hear their results and
		thus get out of interest. The human ear normally is not able to
		hear sound above 20 kHz.
	    </para></listitem>
	    <listitem><para>
	        The signal contains <emphasis>noise</emphasis>.
		Noise is the most ugly enemy of everyone who has to handle audio
		signals in any way. Noise is a typical analogue effect, that makes
		the audio signal "unsharp" and disturbed, it is always present
		and cannot be avoided. One can only try to use high quality
		components that produce as low noise as possible, so that one
		can't hear it.
		Normally noise has a certain volume, so that the interesting sound
		should be much louder in comparism to the noise. This is called the
		<emphasis>signal to noise ratio (SNR)</emphasis>, the higher it is
		the better the sound's quality will be. Sounds that have
		lower volume than the noise cannot be heart.
	    </para></listitem>
	</orderedlist>
    </para>

</sect1>

<sect1 id="digitalization"><title>Digitalization</title>

    <para>
	When we want to store and play audio in a computer, we must convert
	the analogue sound into digital data first. This process is called
	<emphasis>digitalization</emphasis>. It converts an electronic
	signal into a sequence of digital values.

	</inlinemediaobject>
    </para>
    <para>Digitalization of the electronic signal</para>

    <para>
	The conversion can be understood as a repetitive measurement of the
	electonic signal's value at certain time, thus taking a
	<emphasis>sample</emphasis> of the signal. The result is then encoded
	as a digital value.
    </para>
    <para>
	The sampling could be done in arbitrary distances or in constant
	intervals. The later method is much easier to handle, and thus it
	is normally used, with a constant rate - the so-called
	<emphasis>sample rate</emphasis>. Usual sample rates are 8000,
	11025, 22050, and 44100 samples per second. In practice sample
	rates are also given as frequencies, in Hz or kHz.
    </para>
    <para>
	The sample rate limts the
	highest frequency a digitized signal can represent. Due to
	Shannon's theoreme the highest usable frequency is half of the sample
	rate, so with 44.1 kHz sample rate you cannot sample signals with
	more than 22 kHz. To avoid a violation of that half-sample rate
	rule, your soundcard already has built-in filters that filter away
	frequencies that are higher than half of the used sample rate.

<sect1 id="sample-encoding"><title>Sample Encoding</title>

    <para>
	The result of the digital sampling process is a sequence of single
	<emphasis>samples</emphasis>. One sample is a digital representation
	of a signal's value at a certain time.
    </para>
    <para>
	The value of a sample can be interpreted and encoded in several ways.
	The simplest one is <emphasis>linear</emphasis> encoding. This means
	that each sample's value directly represents the analogue signal's
	value multiplied with a constant factor.
	This is easy to handle, but has the disadvantage that
	noise will be audibles especially on low amplitudes, where it disturbes
	most, and less audible on high amplitudes, where it is less audible.
    </para>
    <para>
	One way to reduce the influence of noise is <emphasis>non-linear</emphasis>
	encoding. This means that lower amplitudes are amplified before processing.
	As lower amplitudes are amplified,
	their distance from noise increases and the quality improves. The most
	common methods for this are <emphasis>A-Law</emphasis> and
	<emphasis>U-Law</emphasis> encoding - some standardized logarithmic
	amplification curves, used in digital telephony (ITU G.711 standard).

<sect1 id="sample-formats"><title>Sample Formats</title>

    <para>
	Samples can be stored in different formats and precisions. The most common
	ones are integer (fixed-point) formats, that store values with
	<emphasis>fixed	quantisations</emphasis>.
	Depending on where the zero line is defined, it
	has to be destinguished between <emphasis>unsigned</emphasis> (only positive
	values, "zero line" is at half of the numeric range)
	and <emphasis>signed</emphasis> (positive and negative values)
	integer formats.

    <para>Unsigned Format</para>
    <para>
	As the
	quantisation looses some accuracy, it produces noise, the so-called
	<emphasis>quantisation noise</emphasis>. That kind of noise has more effect
	on low amplitudes, so this method of storing samples is not optimal, but
	quite easy and very fast to handle (computers are fast in calculating with
	fixed point numbers).
    </para>
    <para>
	The second way of encoding samples is with <emphasis>floating point</emphasis>
	numbers. With floating point numbers, noise is spread nearly equal over
	all ranges of amplitudes and has advantages especially on low ampliudes.
	However, this format is much slower when used for processing (computers are
	much slower on calculating with floating point values in comparison to
	fixed point numbers).
    </para>
    <note><para>
	&kapp; internally uses <emphasis>signed integer</emphasis> format with
	24 bit precision, stored in 32 bit integers. This has the disadvantage
	of higher memory consumption when processing files with lower precision
	(e.g. 8 bits), but processing 32 bit numbers is very fast and also
	leaves some reserves for internal calculations, as only 24 bits are
	normally used.

    <sect1 id="clipboard"><title>Clipboard</title>

    <para>
    &kapp; unfortunately has to implement and use it's own clipboard. This
    is due to the lack of support for formats other than text and bitmaps
    in the KDE environment and might be solved in some future release.
    </para>

    <para>
    However, this has some disadvantages. So if you want to exchange
    data between two &kapp; instances through the clipboard, you will
    find out that this is simply not possible. Each instance of &kapp;
    uses it's own clipboard and so that can't work.
    </para>

    <para>
    So if you want to make use of the clipboard in &kapp;, you should
    only start <emphasis>one</emphasis> &kapp; instance and use
    multiple &kapp; windows. That's the way it works!
    </para>

    <sect1 id="drag_and_drop"><title>Drag and Drop</title>

    <para>
    &kapp; supports the KDE Drag and Drop protocol. This enables you
    to open files just by picking them up in a <command>konqueror</command>
    window or the Desktop and let them drop into a window of &kapp;.
    </para>

    <para>
    Please note that if you drop a file into a &kapp; window that already
    contains an opened file, the currently opened file will be closed first
    and then the file you dropped will be opened in it. If you don't want that,
    you should open a new empty &kapp; window first.
    </para>

    <para>
    You can also select a range of samples and drag or drop them into
    a &kapp; window. Per default the drag operation is done in
    <emphasis>move</emphasis> mode where the selected range is deleted
    from the original place and inserted at the drop position.
    By pressing the <keycap moreinfo="none">Ctrl</keycap> key you can
    modify this and drag in <emphasis>copy</emphasis> mode instead.
    </para>

    <sect1 id="command_line"><title>Command Line</title>

    <para>
    If you start &kapp; from the command line, you can specify a list
    of files that should be opened. The first specified file will be opened
    first, then the other files. Each file will be opened in an own new
    window of the same &kapp; instance. If you specify wildcards, you can
    open a large number of files at once.
    </para>
    <para>
    For example, the following command starts a &kapp; and opens all sounds
    of the KDE window manager, each in a new window:
    <screen><prompt>% </prompt><command>kwave <filename>/opt/kde2/share/sounds/KDE_Window*.wav</filename></command></screen>
    </para>

    <para>
    In addition to a list of files, you can specify a list of
    <emphasis>Xt toolkit</emphasis> options like <literal>-geometry</literal>
    for specifying the size and/or position of the first opened &kapp;
    window and or <literal>-display</literal> for starting the &kapp; on a
    different display.
    </para>

    <para>
    For example, the following command starts a &kapp; window with an initial
    width of 600 pixels and a height of 400 pixels, with the right border
    positioned 30 pixels away from the right and 0 pixels away form the top
    of the screen.
    <screen><prompt>% </prompt><command>kwave <parameter>-geometry 600x400-30+0</parameter></command></screen>

    <sect2 id="file_formats"><title>Supported File formats</title>
	<para>
            The favourite file format of &kapp; is (like you can guess from the
            name) <filename>.wav</filename>. This format is very common to other
	    "operating systems" and also is commonly used within the KDE environment.
        </para>
<!-- @TODO@ disabled, will be re-integrated in v0.6.5 or later...
        <para>
            The second format that &kapp; supports is "ASCII". You can import from
            and export to ASCII, but always be aware that storing in this format
            might produce very large files! Currently &kapp; only supports
            ASCII files with only one channel (mono), support for multiple channels
            will be added in some future version. The file format will be described
	    <link linkend="ascii_format">below</link>.
        </para>
-->
	<para>
	    Additionally &kapp; supports many other common formats through the
	    <ulink url="http://oss.sgi.com/projects/audiofile/">audiofile</ulink>
	    plugin. You can import files like <filename>*.au</filename> and
	    <filename>*.snd</filename> (NeXT,Sun Audio),
	    <filename>*.aiff</filename> (Audio Interchange Format) and
	    <filename>*.sf</filename> (Berkeley,IRCAM,Carl Sound Format).

    </sect2>

    <sect2 id="converting_to_and_from_wav">
    <title>Converting to and from .wav</title>

	<para>
	    The best way to work with formats other than those supported by
	    &kapp; is to use an external converter program.
	    A good set of tools for this is in the
	    <ulink url="http://home.sprynet.com/~cbagwell/sox.html">SoX</ulink>
	   package, they have also some nice documentation! Take a look at

	</para>

	<para>
	    The plans for future include support for import and also export filters
	    for more formats and maybe some filter that uses a user-defineable script
	    with a call to an external filter, so that even formats not supported
	    by <literal>SoX</literal> (like MP3) can be read and/or written. Currently
	    &kapp; only is able to save files in <filename>.wav</filename> format.

    <sect2 id="ascii_format"><title>Format of ASCII files</title>
	<para>
	    The ASCII format is quite useful for scientific and educational
	    purposes.
	    Due to it's simple format, you can either write simple
	    files on your own with a text editor or you can use the output
	    of an other application and convert it into ASCII. As the format is
	    <emphasis>really</emphasis> simple, you
	    should not have big problems in writing a converter and most scientific
	    applications use to have some kind of their own ASCII format for
	    export.
	</para>

        <para>
            The format of an ASCII file is quite simple and has the following rules:
            <orderedlist>
            <listitem><para>
		Each line represents one sample.
	    </para></listitem>
            <listitem><para>
		Lines might end with a carriage return and/or a line feed
		character (so DOS files are supported too). But when saving,
		files will always be saved with line feed character as the
		end of the line.
	    </para></listitem>
            <listitem><para>
		Empty lines are ignored.
	    </para></listitem>
            <listitem><para>
		Values can be are given in any format that the C library of
		your system is able to read and interprete as a floating
		point or integer number. But when saving, &kapp; will save
		as in signed floating point format with 9 decimals.
		</para><para>Example: <literal>-7.06999982e-01</literal>
            </para></listitem>
            <listitem><para>
		All values are expected to be in signed format. So if you
		import a file with only positive values, you will only see
		samples that are above the zero line.
            </para></listitem>
            <listitem><para>
		Values can be specified in any range, &kapp; always
		does a first pass over the file to get the highest absolute
		value and defines that value as "100%" before really reading
		in the file.
            </para></listitem>
            <listitem><para>
		Internally all values are stored with 24 bit precision (signed).

    <sect1 id="selecting"><title>How to select</title>

    <para>
    &kapp; allows you to select a continuous range of samples as well as any
    combination of channels (if you edit a multi-channel file). By selecting
    a range of samples (time scope) all following commands will be limited to
    that range and by de-selecting a channel it's content will not be changed.
    </para>

    <sect2 id="selecting_channels"><title>Selecting channels</title>
    <para>
    Selecting or de-selecting a channel is quite simple. Just click on the
    lamp symbol on the left side of the signal to toggle it's state:
    </para>
    <para>
    <inlinemediaobject>
	<imageobject>
	<imagedata fileref="light_on.png" format="PNG"/>
	</imageobject>
	<textobject> <phrase>green lamb</phrase> </textobject>

    a green lamb means "enabled", whereas
    </para>
    <para>
    <inlinemediaobject>
	<imageobject>
	<imagedata fileref="light_off.png" format="PNG"/>
	</imageobject>
	<textobject> <phrase>red lamb</phrase> </textobject>
    </inlinemediaobject>
    a red lamb means "disabled".
    </para>

    <note><para>
    Note: If a channel is de-selected it will also not be audible for playback!
    </para></note>
    </sect2>

    <sect2 id="selecting_samples"><title>Selecting samples</title>

    <para>
    If you select a range of samples in &kapp;, that range will be
    <emphasis>inclusive</emphasis>. That means that the first and the last
    selected sample both belong to the selection and will be used for the
    following actions. So even if you not selected a <emphasis>range</emphasis>
    but only a single sample, the selection will never be really "empty". So for
    example if you see no selected range, the "delete" function applies to that
    single sample.
    </para>

    <para>
    The easiest way of selecting a range of samples is just to do that
    with mouse. It works like you are used from other applications: just press
    the left mouse button at the point you want to let the selection start
    and release the button where you want it to end.
    </para>
    <para>
    If you want to adjust or move the selection's start or end, you can move the
    mouse cursor near to the start or the end of the selection until it changes
    from the standard arrow cursor into the left-right arrow cursor and then
    press the left mouse button and adjust.
    </para>
    <para>
    You can also extend or shrink the selection to a specific point by holding
    down the shift button while klicking with the left mouse button. Depending
    on which border is nearer, the left or right border of the selection will
    be set to a new position.
    </para>

    keyboard shortcuts:

	    <question>
	    	<para>
		    Which sound cards does &kapp; support?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    &kapp; does not need support for any special sound card.
		    The sound card only has to be supported by your
		    operating system and &kapp; uses it's interface to the
		    operating system's sound driver through a standard
		    interface. So &kapp; can play on any sound card that
		    KDE is able to play on.

	    <question>
	    	<para>
		    Why are some menu entries / features always disabled?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    This is just because we decided that those actions
		    are not working stable enough to present them to
		    the normal user and therefore disabled them to
		    avoid trouble. You will get access to them if they
		    are tested and stable enough.
		</para>
	    </answer>

    	<qandaentry>
	    <question>
	    	<para>
		    Why does &kapp; consume more memory than it can be
		    expected from the size of the opened file?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    The reason for this is that &kapp; internally stores
		    all samples in 32-bit integers. This was easy to program,
		    made the application faster and a bit more reliable.
		    So if you load an 8-bit file with about one megabyte
		    it will consume about four megabytes.
		    Maybe we will change this somewhere in the future...

	    <question>
	    	<para>
		    Which sound formats does &kapp; support?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    &kapp; currently supports .wav files with 8, 16 and
		    24 bits per sample, with any number of channels
		    (of course including mono and stereo). Additionally it
		    can import all file types that libaudiofile supports.
		</para>
	    </answer>
	</qandaentry>

    	<qandaentry>
	    <question>
	    	<para>
		    What if I have files with a format not
		    supported by &kapp;?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    If you have to work on an other format, you can convert
		    it into .wav format. A good set of tools for this is
		    in the
	            <ulink url="http://home.sprynet.com/~cbagwell/sox.html">SoX</ulink> package, they have also some nice
		    documentation!

	    <question>
	    	<para>
		    I get errors when I want to do playback?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    Maybe you have choosen a combination of playback
		    rate and sample size that is not supported by your
		    sound driver and / or sound hardware. Try playback with
		    8 bits per sample and mono first, this should always
		    work. Then try to increase the bits per sample and
		    stereo playback step by step. Note that some playback
		    rates are not at all supported by some sound hardware.

	    <question>
	    	<para>
		    The playback seems to do something but I hear nothing?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    Maybe you have forgotten to increase the volume of
		    the playback channel. &kapp; is not responsible for
		    changing the playback volume.
		</para>
	    </answer>

    	<qandaentry>
	    <question>
	    	<para>
		    Some files are played with half-speed?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    Try choosing a different sound playback device.

	    </answer>
	</qandaentry>

    	<qandaentry>
	    <question>
	    	<para>
		    The playback sometimes is disturbed and interrupted?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    You should increase the size of the playback buffer
		    to get a "smoother" playback (this also makes the
		    playback control reacting a bit slower).
		</para>
	    </answer>
	</qandaentry>

    	<qandaentry>
	    <question>
	    	<para>
		    The playback does not stop if I immediately
		    press the stop button?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    The reason for this is that the sound driver already
		    has received some playback data from &kapp; at the
		    moment when you press the stop button. Decrease the
		    size of the playback buffer and it should react faster
		    (but makes interruptions more probable).
		</para>
	    </answer>

    	<qandaentry>
	    <question>
	    	<para>
		    Is ALSA supported?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    Sorry, currently we don't have direct support for ALSA, but
		    since version 0.6 &kapp; has support
		    for <ulink url="http://www.arts-project.org/">aRts</ulink>,
		    which can use ALSA.
		</para>
	    </answer>
	</qandaentry>

    	<qandaentry>
	    <question>
	    	<para>
		    What about playback with 24 and 32 bits per sample
		    or more than two channels?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    This is another feature that might get implemented
		    in <ulink url="http://www.arts-project.org/">aRts</ulink>,
		    so we wait for aRts to support it.

	    <question>
	    	<para>
		    What about MP3 support?
		</para>
	    </question>
    	    <answer>
	    	<para>
		    Not for the moment, but maybe MP3 import / export already
		    is on the TODO list at a very high position.
