Re: [Savonet-users] errors in WAV header

[Peter R. <pet...@gm...>]

Hi,

the first record is done and encoded fine when using the 'duration' parameter:

qwavheaderdump test_18:00.wav
test_18:00.wav (635040044 bytes):
     riff: 'RIFF'
     riff length: 635040036
     wave: 'WAVE'
     fmt: 'fmt '
     fmt length: 16
     format: 1
     channels: 2
     sample rate: 44100
     bytes/second: 176400
     bytes/sample: 4
     bits/sample: 16
     data: 'data'
     data length: 635040000

Thanks for fixing this!

I have written a issue for documentation : http://dev.sourcefabric.org/browse/LS-552

BR, Peter
