Hi, I'm using speex 1.1.4 and when I query SPEEX_GET_SAMPLING_RATE as in speex_encoder_ctl ( m_pEncoderState, SPEEX_GET_SAMPLING_RATE, &m_SampleRate ); I get 2 The encoder is initialized with m_pEncoderState = speex_encoder_init ( &speex_wb_mode ); On the decoder side, the correct sampling rate is returned: m_pDecoderState = speex_decoder_init ( &s...

...only happens with speex_wb_mode. But like I said, it is because in wideband mode, the function sb_encoder_init is called and this function initializes the sampling rate using speex_*de*coder_ctl instead of speex_*en*coder_ctl In narrowband mode, the sampling rate is just initialized to 8000 st->sampling_rate=8000; BTW, I saw that my email was added to an existing thread instead of creating a new thread.

Attached is the amended second patch. It now extends the multistream API as well to 80/100/120 ms and incorporates changes based on Mark's comments.

Hi, Do you get that problem with speex_nb_mode too (or only speex_wb_mode)?

...ex decodes the 21-byte packets I recieve into 160 bytes and I can play them fine, but when I encode, the result is 38-bytes long. I have read that 38 bytes means that it is encoding at 15KHz, but I have set it to nb-mode and when stepping through the libspeex encoding sourcecode, I see that st->sampling_rate is 8000. Any idea why I speex-compress 160 bytes to 38 and not 21? Thanks in advance. y -------------- next part -------------- An HTML attachment was scrubbed...

...> >------------------------------------------------------------------------- Hello, I think I will ask my question in an other way because It was not really a success :-) Does the AEC works in WB yet ? In mdf.c, I can read : /* FIXME: Make that an init option (new API call?) */ st->sampling_rate = 8000; Does it mean that the AEC in WB is not fixed yet ? Thank you for your answer, I really need to now if I have to work on that... JC.

Hello, I've just caught a strange crash in speex_echo_state_init routine. It happened only on one WinXP machine, while on others using XP, Vista and 7 everything is fine. Crash occures in mdf.c line 434: st->spec_average = DIV32_16(SHL32(EXTEND32(st->frame_size), 15), st->sampling_rate); Got any ideas or should I provide more information of the OS? Thanks a lot!

Hello Ashhar, thanks for your reply, but i'm a bit surprised. 1- Does it mean that it is possible to make a Real Time Encoding/Decoding with SPEEX on iPhone ? 2- What parameters have been used (QUALITY, SAMPLING_RATE, BITRATE) ? and what kind of CPU load do they measure for that ?

Hi Jean Marc, I found that the AGC API and algorithm has changed in svn head trunk. Is it safe to use it? Or is it for testing purpose only? You also said that VAD in svn is broken in a previous post, is it related to the AGC change? or can we mix the old VAD algorithm with the new AGC safely? kind regards, fredo
