Title: internal audio type encoding
Post by: xyswitchz on March 30, 2018, 05:29:40 PM

In the file echo.sh example file included with yate; raw audio data is redirected back with the cat command.
I want to pipe this to sox to do some processing.

What is the type, encoding, sample of this internal audio format?

Hi,

We used to record files in one of the supported formats and then when call ended we used sox / other programs to convert audio/merge multiple files. When call ended we triggered an external script that triggered processing.

The format should be signed linear, rate 8000, but i'm not 100% sure. You should try to verify this.
