It would be very nice to be able to nail down those server crashes.
I've never seen it crash so much. how clean is your box?

glad to hear you got somewhere.
There must be a problem with my code, yes. All of those parts work
really well on my machine. what distro are you using again? Maybe I
can setup a box and write some install instructions, and fix some bugs.
I will put together some install docs tonight that detail
dependencies and everything else. I'll be sure to look at your emails
for extra clues.
I didn't know that libsamplerate would do everything that you are
looking for. I would use soundtouch if you are just looking for
something to transform some sound, as I think its a lot faster anyway.

finally at last...
i jerked a bit of sound out of pkaudio!
there is probably also something with the wavedecoder, since it doesnt
produced sound for me.

maybe it has something to do with the XRUNs issue that i didnt fix
yet, yet i doubt it...
i already stared to work a bit on an alternative implementation using
RtAudio an some Secret Rabbit Code (libsamplerate), but that is on
hold now.
i much rather use a Qt-style api to do all i need (file loading,
sample rate conversion, audiodevice handling) and more over c-ish
nonsense... ohh, and now i can also prototype in python (the language
that i get paid for to code in -- yet i still suck at it)
i'll write more later, i've got to code a bit now...
_c.

I have updated pkplay to use pk.options. You might check out that file to learn how to use pk.options. you can also grep the tree for OptionsGroup.

sorry, I just realized that I hadn't added pk.options support to pkplay yet. won't take long. On another note. I would suggest that when you run into a problem like this, particularly with python code, go ahead and start reading the code in question. This will help especially because you are across the world, and it takes us a day to reply to each other. You will find that most of the problems are fairly simple to fix, or to understand (because my code aint perfect yet baby!). I wrote a lot of the source tree in one massive re-write session a few weeks ago, so there are bound to be some small flaws. Thanks fro you input, testing on another platform really helps.

I'm sure its a simple problem. this code hasn't been runon anything other than vanilla fedora3 and gento (works really well on a gentoo box).

hmm. I'm not sure what to say for the crashes, unless you debug pkaudiod (which you can, btw). pkplay is the easiest way to play sound. again, try running everything with verbose on. start_server() has that option, and pkplay should too. look at the pthon code for api references.

the cool thing about this technology is that it is very thin. It would take someone like you a very small amount of time to understand *all* of the functional code. I've already written the necessary subclasses (from pk.gui.pixmapwidgets import *), so it should be very simple to use/improve. On Oct 10, 2005, at 10:55 AM, Patrick Stinson wrote: > excellent!

sorry, sorry, sorry!
i have overseen a c in pyC... sorry.
i fixed the error by importing this file ones from the python prompt
so i got further, but not till the 'end' (a simple sound playing over
my speakers though pkaudio)
afer 'sudo make install'
i tried:
cies@linux:~/src/repos/build/scripts-2.4> ./pkplay
/opt/kde3/share/sounds/KDE_Startup.wav
detected server crash

first off, the compile error i a problem with soundtouch. you have to specify if you want to use float or integer samples using a preprocessor directive in STTypes.h, *before* you compile the library. pkaudio uses float samples. some linux distributions use float samples, some use integer samples. I would just set it to float and install the library yourself. none of the programs that play audio (like pkplay) will work without the server. the server *is* the audio component. as far as the "bad magic number" error from importing the pixmaps file, that's some kind of python error. I have been looking for a good way to package all of the pixmaps for the various parts of my code. ideally there would be a python module that you can just import. Since pyc files are not platform-independent, I should erase that one from version control and replace it with the .py file. There is a compatibility problem with pyuic-embedded pixmap data, between ppc and x86 though, too. It must have something to do with endianness. maybe I should have two copies. I fixed the pixmap problem. 'svn up' and try again. |

in these file i got the compile errors as described below...
repos/pkaudio/modules/pksequencer/sequencermodule.cpp
repos/pkaudio/pkaudio/djengine.cpp
i made it compile by adding the following cast to all method calls to
the soundtouch lib's putSamples and receiveSamples:
"(soundtouch::SAMPLETYPE*)&"
i compiled and 'make installed'-ed
i also had to install a few extra python packages on suse 9.3:
kdebindings3-python, python-xml, python-devel
yet after all this i'm still not able to run it:

This is exactly what I was getting at in my just previous email. You've got it, and if implemented correctly should not be too difficult. The PK::Buffer is fairly simple, in that it reads from a non-buffered device (but I've found that these devices are generally buffered **very** well by the linux kernel itself!). I would be happy to guide you through the parts concerning my classes, and offer appropriate assistance (not much, on my tight schedule). PK::Segment holds a block of audio data, and is meant to contain any simple functions that pretain to that block (like reversing, muting, etc.). So you will probably be using that one too. I think those building blocks should make it fairly easy. let me know how it goes! -P ----- Original Message ----- From: cies <cie...@gm...> Date: Thursday, October 6, 2005 6:39 am Subject: Re: great work! > ohh, and for the x-y axis thing... > since psaux is an accumalated device i want to use one axis for the > scratching and the other for an optical fader. > > this will be an other (in this case non optical) mouse where from i > use the reader machanism to read an optical fader. with way i would > have a heavy duty digital scratching setup. > > with a external keypad i want to implement the general control over > the interface. all USB. > > but first things first. i need a realtime audio class that plays from > -aLot to +aLot. > > > ************** > > okay, i read myself into your lib (mainly the api and some code here > and there). looks neat. > > from what i understand it is basically a heavy abstration of media > (files and hardware) and a simple plugging mechanism, where modules > depend on the eventloop. > > this way the whole of plugging is easier, cleaner and more lightweight > than when using JACK to do this (which results in separate apps) -- > and more important there is a uniform way to handle properties! > > the DJEngine uses SoundTouch for pitch/stretch -ability. > > iiuc you propose to allow backwardsplaying by enableing the buffer > classes to read/walk backward somehow. then still use the soundtouch > classes for pitch/stretch but then to trick it into using the > backwards stream as if it was a regular stream. > > sounds feasable. > > do i understand you right? > > _cies. > |

hi all on the list...
im new, im cies, im from rotterdam,
and i have a compile error when trying to compile PKAudio (is there a
special PKAudio list?)...
i run SuSE 9.3 using python2.4, gcc version 3.3.5 20050117
(prerelease) (SUSE Linux) and qt3.3.4...
i checked out pkaudio from svn today and installed soundtouch by 'make
install' (which make'd without even a warning).

ohh, and for the x-y axis thing... since psaux is an accumalated device i want to use one axis for the scratching and the other for an optical fader. this will be an other (in this case non optical) mouse where from i use the reader machanism to read an optical fader. with way i would have a heavy duty digital scratching setup. with a external keypad i want to implement the general control over the interface. all USB. but first things first. i need a realtime audio class that plays from -aLot to +aLot. ************** okay, i read myself into your lib (mainly the api and some code here and there). looks neat. from what i understand it is basically a heavy abstration of media (files and hardware) and a simple plugging mechanism, where modules depend on the eventloop. this way the whole of plugging is easier, cleaner and more lightweight than when using JACK to do this (which results in separate apps) --=20 and more important there is a uniform way to handle properties! the DJEngine uses SoundTouch for pitch/stretch -ability. iiuc you propose to allow backwardsplaying by enableing the buffer classes to read/walk backward somehow. then still use the soundtouch classes for pitch/stretch but then to trick it into using the backwards stream as if it was a regular stream. sounds feasable. do i understand you right? _cies. |
