Hi all,
How do I write numpy arrays to sound files ?

Hi, This works for me, at least on Windows. Best, James from numpy import arange, sin from waveio import exportWave w=sin(arange(0,2000,0.5)) #simple waveform exportWave('test.wav',8000,w) #8000=sampling rate in Hz.

Hi James, where can I get the module waveio and how do I install the module waveio ? Nils

If you have very basic needs, when python stdlib (as given by James' example) is enough. If you want more control/other file format, then audiolab may be more appropriate. There is a simple API (the so-called matlab API) for wav, aiff, flac and a few other formats, David
Hallo! If you want to have the exact commands: 1) build audiolab (http://www.ar.media.kyoto-u.ac.jp/members/david/softwares/audiolab/) 2) in python: from scikits.audiolab import wavread, wavwrite # read a wave file (audiodata, samplingrate, encoding) = wavread("yourfile.wav") # write a wave file wavwrite(audiodata_as_numpy_array, "youroutputfile.wav", samplingrate) LG Georg David Cournapeau schrieb:

Hi! You may find this example useful: http://neuralensemble.org/trac/NeuroTools/browser/trunk/examples/single_neur... We used scikits.audiolab to record a numpy array and pyaudio to play it on your computer. (and btw, it's an educational example, not scientific!) cheers laurent Le 10 nov. 08 à 10:28, Georg Holzmann a écrit :
