[SoX-users] Asterisk audio files (informational)

[Daniel T. <dt...@vo...>]

Maybe this will help other people looking for this, along with a
search-engine friendly subject line ;)

Asterisk can deal with uLaw, aLaw, or 16 bit signed linear.

For US users:
# sox original.wav -r 8000 -c 1 -e u-law processed.wav
should be adequate. You might need filter options if it doesn't sound good
with your original file.

Since Asterisk can internally convert between the 3 formats in only a
couple
of microseconds per second of audio, it really doesn't matter too much
which you use.

 
(I chose to reply to this thread as it is relevant, and I need to
convert some
files myself so I was thinking about it.)
