Hi there, attached is a patch which adds a speex_preprocess_state_init_from_old function to the preprocessor interface. This is used when you need to spawn a new preprocessor (e.g. due to changed sampling rate), but you want to save (some of) the adaptation the old preprocessor achived. Note that the attached patch, though it apparently does work to at least preserve the gain of AGC, was writen with little to no actuall preprocessor knowledge, and will probably contain bugs. This is not a merge request. If anything, it is a feature request for similar functionality, but writen properly :). It is my temporary sollution though. Peter -- I never made a mistake in my life. I thought I did once, but I was wrong. -- Lucy Van Pelt -------------- next part -------------- A non-text attachment was scrubbed...
