WAV files are usually simple, but can be very complicated. Chrome only
supports one wav codec, which is PCM (uncompressed), and 3 formats within
that:
8 bit unsigned
16 bit signed, little endian
32 bit float, little endian
16 bit is the most common.
If you could upload a sample WAV that you're having trouble with, we could
take a look to see what the problem is.
Chrome8 should support WAV, and Chrome9 has the same support.
Because its uncompressed, if its trying to play from a server, it requires
high speed internet to keep up.
The file is about 1 second of silence which I recorded as I can't use real
voicemails. As you can see chrome refuses to play it.
Comment #8 on issue 67740 by fbarch...@chromium.org: Failure to open wav
files
http://code.google.com/p/chromium/issues/detail?id=67740
ffmpeg says
Stream #0.0: Audio: gsm_ms, 8000 Hz, 1 channels, s16, 13 kb/s
gsm is not a codec Chrome supports.
2 work arounds
a) convert to uncompressed wav
ffmpeg -i test.wav -acodec pcm_s16le test2.wav
Duration: 00:00:01.40, bitrate: 128 kb/s
Stream #0.0: Audio: pcm_s16le, 8000 Hz, 1 channels, s16, 128 kb/s
b) make or download a full ffmpeg with dlls and use those in your chrome.
