<P>Hi,</P>
<P> </P>
<P>I've started thinking about speex and speex stream. I wonder to know if speex can do this:</P>
<P> </P>
<P>Let assume we already have PCM stream encoded with speex (e.g. saved in a file or memowy):</P>
<P> </P>
<P>frame1 | frame 2 | frame 3 | frame 4 | ... | frame N-1 | frame N,</P>
<P>where frame n is a single (20 ms) speex frame.</P>
<P> </P>
<P>Now we decompress only a part of that stream, let say (3 frames):</P>
<P> </P>
<P>frame 2, frame 3, frame 4 -> pcm_frame_2, pcm_frame_3, pcm_frame_4,</P>
<P>where pcm_frame_n is a pcm format signal generated by decoding n-th speex frame</P>
<P> </P>
<P>and then </P>
<P> </P>
<P>decompress another path od the same encoded stream:</P>
<P>frame 1, frame 2, frame 3, frame 4 -> pcm_frame_1', pcm_frame_2', pcm_frame_3', pmc_frame_4',</P>
<P> </P>
<P>Question: pcm_frame_2 ?? pcm_frame_2' will by identical?</P>
<P> </P>
<P>I thik, above quiestion coul'd be simplified to: "is speex stateless?"</P>
<P> </P>
<P>Regards</P>
