...big files and then to access to small portions and decode only those parts. I use the streaming mode(the sample codes provided on the web-site) without the Ogg packaging which seems useful to me for seeking in time. When I seek in time by just skipping packages, reset by: speex_decoder_ctl(state, SPEEX_RESET_STATE, NULL); and starting decoding, I see that the quality of decoding varies depending on the initial frame characteristics. It seems that the signal gets close to the original quite fast when the first frames are unvoiced. If I start decoding in the middle of a voiced chunk then decoding quality is co...

...nd decoder become NaN. The decoded sound buffers all come out as a series of NaNs. Building libspeex disabling floating-point computation fixes the problem, but is unsatisfying :) In the course of debugging this I did find a (maybe) bug in the narrowband libspeex code. The control message SPEEX_RESET_STATE to the decoder (I think) should reset the high-pass filter buffer to zero. We're actually using the speex library through foreign function calls in Haskell (using ghc), which contributes to the decoding glitch in two ways: - Our program is very concurrent, with many lightweight threads...

Hello! I should have asked this earlier, but... :) We're returning to voice processing in our app now, in which we're trying to achieve n-way full duplex voice in a 3d environment. Since Speex is a single voice stream CODEC, we've been looking at having each client upload its stream to the servers, which multiplex several spatially nearby active channels back down to the
