 |
|
I am using centos 6.7 64 bit and sox to convert gsm files to wav.
When I do that I used to get a header like:
RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz
Now I get a header like:
RIFF (little-endian) data, WAVE audio, GSM 6.10, mono 8000 Hz
And the file does not play in the browser (chrome).
I use sox file.gsm file.wav
I have tried: sox file.gsm -r 8000 -c 1 file.wav
If I use the rasterisk convert file method - that works and has PCM not GSM but I need to use sox. Reference:
http://www.voip-info.org/wiki/view/Convert+WAV+audio+files+for+use+in+Asterisk
How does one correctly convert gsm to wav for play in the browser?
Thanks,
Jerry |

Never been a fan of using a sledge hammer when a tack hammer will do.

I use:
sox\
input.xxx\
--bits=16\
--channels=1\
--encoding=signed-integer\
--rate=8000\
output.wav
Followed by a trip through:
normalize\
--amplitude=-22dB\
output.wav

Thanks in advance,
