Some Speex AGC Questions
I'm attempting to use speex preprocess for automatic gain control in an
application I'm working on and could use some help.
I'm using Opus as my codec. In order to keep the number of packets down,
I'm using 60msec frames. I'm sampling at 48KHz as is recommended for Opus.
So, the frame length is 2880 samples and the sampling rate is 48000. The
source of the data is a microphone using ALSA. That platform is Ubuntu.
The version of speex is 1.2rc1.
When I run with the default settings, the audio seems OK...
