Writing a aiff audio file problem?

[jym]

Hi all

I can not creat a usable audio file in the aiff format. The example code
below creates a wav file that I can listen to just fine. However, I just get
noise when I listen to the resulting aiff file. Is this a byte order
problem? I am using Python 2.5.2 on Windows XP. Any guidance on this issue
would be appreciated.

Thanks

import pyaudio
import wave
import sys
import aifc

chunk = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 8000
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output"

p = pyaudio.PyAudio()

stream = p.open(format = FORMAT,
                channels = CHANNELS,
                rate = RATE,
                input = True,
                frames_per_buffer = chunk)

print "* recording"
all = []
for i in range(0, RATE / chunk * RECORD_SECONDS):
    data = stream.read(chunk)
    all.append(data)
print "* done recording"

stream.close()
p.terminate()

#write data to AIFF file
data = ''.join(all)
af = aifc.open(WAVE_OUTPUT_FILENAME + ".aiff", 'wb')
af.setnchannels(CHANNELS)
af.setsampwidth(p.get_sample_size(FORMAT))
af.setframerate(RATE)
af.writeframes(data)
af.close()

# write data to WAVE file
wf = wave.open(WAVE_OUTPUT_FILENAME + ".wav", 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(data)
wf.close()
