[Speex-dev] Multi-channel encoding

[Paolo Dozio]

Hi,
I have read the news about Speex 1.2rc1 is out:

"This release adds support for acoustic echo cancellation with multiple microphones and multiple loudspeakers. It also adds an API to decorrelate loudspeaker signals to improve multi-channel performance...."

I have to encode a 4 multichannels audio file. The single channel is not correlated with other.
What kind of parameter I have to pass to speexenc?
I can only use stereo mode?
In stereo mode the channels must be correlated?

Many thanks.
Paolo.
