Summary: Wave files from SoX Rate Converter in 24bits can't be read

Initial Comment:
The files generated from the Rate converter in the 24 bit format (44.1kHz -> 88.2 kHz) are not recognised by Foobar also recognised by VLC.

Regards,
Jean

There are two changelog entries from 14.3.2 that may be related:
– Fix RIFF chunk length error when writing 24-bit files. (David Bryant)
– 24-bit WAV files were leaving channel maps unassigned. Change to use
common channel mappings based on channel count.  This allows to work more
seemlessly with other apps such as WavPack and Foobar2000. (David Bryant)

So it might be fixed.

Hmmm... so far, not able to recreate this problem.

Perhaps you could try generating these 2 test files:

sox -b 24 -c 2 -r 96k -n -t wavpcm wavpcm.wav synth 1
sox -b 24 -c 2 -r 96k -n wav.wav synth 1

then testing with various players.

Here's what I find:

VLC 0.8.6a works with both

Audacity (libsndfile 1.0.17) works with both

foobar 0.9.6.1 works only with wavpcm.wav

Windows media player 10.00.00.4036 works only with wav.pcm

(pretty much as expected.)

One more(perhaps a workaround for the time being):

If I  run: 

sox in.wav -t wavpcm out.wav vol 0db 

out.wav is readable even though -V says  vol has no effect!

I forgot to mention:

I get the same result if I use -t wavpcm or -t wav as mentioned in FAQ

Hi there

The same over here: 

Sox  Revision 14.2.0

Input is 24/2/96000 wav

Command: sox in.wav out.wav 

sox -V output:

sox sox: effects chain: input      96000Hz 2 channels 24 bits (multi)
sox sox: effects chain: output     96000Hz 2 channels 24 bits (multi)


In/Out Files:

124841432 2009-01-16 10:25
02-John_Gorka-The_Gypsy_Life-I_Saw_A_Stranger_With_Your_Hair.wav
124840424 2009-01-16 10:22 02test.wav


Is the format or header changed?? Even -t wav didn't work.
