Hi!
How can I put wav file into table so I can read it
with lookup? Which object to use? SndTable is for raw
files. So which one is for wav?
Thanks
Bosko

you can use Unit() to generate a constant signal and Mixer() to add it. ----- Original Message ----- From: "bosko milakovic" <bmi...@ya...> To: "sndobj-devel" <snd...@li...> Sent: Sunday, January 06, 2008 10:35 PM Subject: [Sndobj-devel] Simple signal math > Hi! > > How can I add a scalar to signal? > I was trying this: > import sndobj > > tab = sndobj.HarmTable() > osc = sndobj.Oscili(tab, 440, 1000) > output = sndobj.SndRTIO(1, sndobj.SND_OUTPUT); > for i in > range(3*int(sndobj.DEF_SR/sndobj.DEF_VECSIZE)): > osc = osc + 2 > osc.DoProcess(); > osc>>output > > but it's not good.

Hi!
How can I add a scalar to signal?
I was trying this:
import sndobj
tab = sndobj.HarmTable()
osc = sndobj.Oscili(tab, 440, 1000)
output = sndobj.SndRTIO(1, sndobj.SND_OUTPUT);
for i in
range(3*int(sndobj.DEF_SR/sndobj.DEF_VECSIZE)):
osc = osc + 2
osc.DoProcess();
osc>>output
but it's not good. Also I was trying examples from
manual but with no luck.
Thanks.
Bosko

Two things: 1. you'll need more volume, 20dB is not enough. Try 96dB 2. don't forget to add gn to the thread. I get sound here with this: import time import sndobj tab = sndobj.HarmTable() osc = sndobj.Oscili(tab,400,400*5) phas = sndobj.Phase(400,osc) readp = sndobj.Lookupi(tab, 0, phas) gb = sndobj.Gain(96, readp) outp = sndobj.SndRTIO(1) outp.SetOutput(1, gb) thread = sndobj.SndThread() thread.AddObj(osc) thread.AddObj(phas) thread.AddObj(readp) thread.AddObj(gb) thread.AddObj (outp, sndobj.SNDIO_OUT) thread.ProcOn() time.sleep(3) thread.ProcOff() ----- Original Message ----- From: "bosko milakovic" <bmi...@ya...> To: "victor" <Vic...@nu...>; "Bosko&Toma Milakovic" <bos...@gm...>; <snd...@li...> Sent: Wednesday, December 12, 2007 9:24 PM Subject: Re: [Sndobj-devel] Phase modulation > Thanks, but it doesn't work. > I've added a Gain: > readp = sndobj.Lookupi(tab, 0, phas) > gn = sndobj.Gain(20, readp) > > and also to output: > > outp = sndobj.SndRTIO(1) > outp.SetOutput(1, gn) > > but still no sound. > > Any other ideas? > > Bosko > > > > > --- victor <Vic...@nu...> wrote: > >> The readp output needs to be amplified.

Thanks, but it doesn't work. I've added a Gain: readp = sndobj.Lookupi(tab, 0, phas) gn = sndobj.Gain(20, readp) and also to output: outp = sndobj.SndRTIO(1) outp.SetOutput(1, gn) but still no sound.

Try to run the line g++ -o python/_sndobj.so -bundle -framework python -framework coreaudio python/AudioDefs_wrap.os -Llib -lsndobj -lSystem from your command-line to see if it does anything. The error message seems to indicate that you need to link to libSystem. Another thing you can try is to remove your MacPython 2.5 installation and re-build with Apple's supplied Python 2.3 that is in your system.

Hi! I'm having difficulties with object EnvTable. With this: points = [1000,1000,0] lens = [30,30,30] env = sndobj.EnvTable(100, 3, 0, points, lens) I get an error that there's wrong number of arguments. When I change it to this: env = sndobj.EnvTable() env.SetEnvelope(3, 0, points, lens, 0) I get error that argument 4 of type 'float *' I also tried to convert points and lens lists to floats but that didn't helped.... What am I doing wrong? Thanks Bosko |

One further piece of information: I can confirm that this is libsndobj issue, and not specifically a pysndobj issue. I get the same trouble: stuttering audio, with the C++ examples e.g. streson. In fact with streson, the problem is slightly worse. Jamie -- www.postlude.co.uk |

In that case something is definitely wrong, either with my sndobj
install, or with my pysndobj code. Even with a buffer size as big as
8192, I still get a few clicks when using the ALSA module. OTOH, I can
get completely clean sound with a buffer size of 128, on the same laptop
under OS X. FWIW, here's the test code:
import sndobj
import time
outtype = 'ALSA'
tab = sndobj.HarmTable()
if outtype is 'JACK':
osc = sndobj.Oscili(tab, 440, 0.2)
outp = sndobj.SndJackIO('sine', 1, sndobj.SND_IO)
else:
osc = sndobj.Oscili(tab, 440, 2000)
outp = sndobj.SndRTIO(1, sndobj.SND_OUTPUT, 8192)
mod = sndobj.Oscili(tab, 44, 2)
osc.SetFreq(440)
outp.SetOutput(1, osc)
thread = sndobj.SndThread()
thread.AddObj(osc)
thread.AddObj(outp, sndobj.SNDIO_OUT)
thread.ProcOn()
time.sleep(10)
thread.ProcOff()
Using SndJackIO is even worse: after the script finishes execution, the
JACK server hangs with the glitchy sine wave seemingly stuck in its
buffer.
BTW, I don't think this is an issue with my laptop/audio config, I
generally operate PD with a blocksize of 64, with no troubles.

On Windows, soundcards are listed by number. You can run
SndObj.ListDevices() to get a list of MME devices and
then use the number as the device number argument to
the SndRTIO object constructor (look at the manual).
Victor
eg:
>>> sndobj.ListDevices()
Input devices:
device ID: device name
0 : Aureal Audio
1 : SoundMAX Digital Audio
2 : M-Audio Quattro
Output devices:
device ID: device name
0 : Aureal Audio
1 : SoundMAX Digital Audio
2 : M-Audio Quattro

Dear pySndObj-developers,
While I am not an advanced programmer, I use the scripting language python
quite often to make prototypes. For a project I am working on now, I need
more advanced sound output, for which I thought pySndObj was most
appropriate/up-to-date. I am running Python 2.5.
What I would like to have is multiple channels of audio through
non-standard (not selected as default in Window's Configuration Panel)
soundcards simultaneously in Windows. Code I am testing with is included
below (note this is my first time I ever have done something with
pySndObj).
>From the C++ documentation (p. 161) I derived that I somehow need to
create a SndObject that needs to be passed to SndRTIO, containing
information about the other soundcard... but it is unclear to me how to
accomplish this in python. A typical error I get is:
NotImplementedError: Wrong number of arguments for overloaded function
'new_SndRTIO'.
Possible C/C++ prototypes are:
SndRTIO(short,int,int,int,int,SndObj **,int,float,int)
SndRTIO(short,int,int,int,int,SndObj **,int,float)
SndRTIO(short,int,int,int,int,SndObj **,int)
SndRTIO(short,int,int,int,int,SndObj **)
...
Could someone help me out? Thank you very much in forward!
Yours,
Maarten Brouwers

import sndobj
import time
import sys
wavfile = sndobj.SndWave('anger.wav', 3, 1,16)
wavsound = sndobj.SndIn(wavfile,1)
#SndRTIO(short,int,int,int,int,SndObj **,int,float,int)
objs = sndobj.intArray(1)
objs[0] = 256
objs[1] = 48000
objs[2] = 2
objp = objs.cast()
#outp = sndobj.SndRTIO(1, sndobj.SND_OUTPUT, 128, 20, sndobj.SHORTSAM, objp)
outp = sndobj.SndRTIO(1, sndobj.SND_OUTPUT)
outp.SetOutput(1, wavsound)
IT = sndobj.SndThread()
IT.AddObj(wavfile,sndobj.SNDIO_IN)
IT.AddObj(wavsound)
IT.AddObj(outp, sndobj.SNDIO_OUT)
IT.ProcOn()
time.sleep(2)
IT.ProcOff()

SndWave::Output() will return a single sample from a single channel in an output block (after a Read operation). This is a method inherited from SndIO. If you connect a SndIn object to a SndWave channel, then you have several ways of getting samples (see the man page for the SndObj class) Victor > > > > I am not sure if this is possible, since the signals are > internal, but is there a way to access the signal samples > individually or in groups?

I am not sure if this is possible, since the signals are internal, but is there a way to access the signal samples individually or in groups? Say if I load in a sound file into a SndWave object, can I access the sample values? |

Perhaps you would need to adjust buffer sizes etc with the alsa module. In my experience all works very well with both alsa and jack, but jack perhaps the best for latency. But also, in my laptop, with Fedora, I have been running very small buffers with alsa, without any problems. What you describe is basically the fact that the computer is not keeping up with the audio card, so causing dropouts.

Hi all, I'm interested in using pysndobj to do some audio development work. I've managed compile everything from CVS without a hitch - nice work with the build system! I have it working and it sounds nice on OS X. However, on GNU/Linux the audio quality is dreadful with the audio breaking up, and lots of clicks. I get this with the default audio driver (alsa?). The problem is worse using Jack - I just get a load of clicks where a sine wave should be! Ubuntu Gutsy (2.6.20-16-lowlatency) scons pythonmodule=True Anyone got any suggestions about how to fix this. I'm new to sndobj/pysndobj. Thanks, Jamie -- www.postlude.co.uk |

Hi! How can I do some simple math operations with signals(multiplication,sum) in Python? For example like in PD when osc~ is multiplied with 0.5 the amplitude is half lower... In sndobj manual I found it under sndobj class but when I tried it it didn't work. Probably for Python it has to be done in different way(?). Thanks Bosko |

hi, bellow is a link, an ongoing work of a tutorial for audio manipulations using python. Its ideally directed to non-programmers with some basic knowledge of physics and sound manipulation processes. There is a part dedicated to PySndObj, part 4- The PySndObj module. Is that ok? You can think of the reader as capable of follow what is on part 2 (about python from zero). And part 3 (using the standard library for audio). Some "from sin to modulating FMs" PySndObj scripts are already there, and some other stuff, but no explanatory comments or technical texts of PySndObj usage/functionalities. Any correction or further code (not in manual) is helpful as is any explanation oriented to non-programmers or text corrections. Feel free to name your self as a contributor. A list of important related links is in the ToDo list. The text is in Portuguese still, but the code can be followed, and modifications in English can be done of course. I can translate some portions from time to time with pleasure. You need to register to add/edit, but it seems to be just for version control. I can edit/add if wanted, or help. link: http://www.estudiolivre.org/tiki-index.php?page=python-e-som-tutorial thanks, best, Renato 2007/8/20, Victor Lazzarini < Vic...@nu...>: > > I have released new packages for SndObj and PySndObj.
