Speex dev - Aug 2004 - maximum frame-length for narrow, wide and ultrawide encoding

I take care of that myself.

Yeah, will, I did that. I think I'll implement the decoder to see if
all goes well at all.

I found the problem (I think):

I was setting
        speex_encoder_ctl(libspeex_enc_state, SPEEX_SET_BITRATE, &bitrate);
to my bandwidth (32KB -> 256Kb).

If I remove this line, the data is not compressable with zlib :o)
Tomorrow I'll try decompressing things.

Hi,

What is the maximum frame-length that libspeex will produce for narrow,
wide and ultrawide encoding?

Thank you.

In normal operation (no in-band side information, like requests, ack,
stereo, ...), the max size for a frame is 62 bytes in narrowband, 106
bytes for wideband and 110 bytes for ultra-wideband.
