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 ( &spee...

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

Hello The st->zeta pointer isn't freed in the speex_preprocess_state_destroy() function of the preprocess.c file (alloced in line 167). It's in Speex 1.1.4 by the way. I'm trying to make the denoiser work with my application and has got reasonable noise reduction after applying the denoiser. I, however, haven't been able to find any information of what the purpose of

First of all, Flash Player can only publish Speex at 16 kHz. 20 ms of audio (320 samples) will result in compressed payload size of 106 bytes (42.4 kbps). When Flash Player sends a TC message, there is 11 bytes TC message header and a single byte of audio message header.
