...ere is silence in media using speex? Is there any API which decides that the audio data only contains silence? Basically i will have PCM linear data, I want to know whether it is complete silence. Is it that during encoding speex_bits_write will return a lesser number if the audio at byte_ptr contains silence? thanx, Rahul -- Rahul Arvind Jadhav Web: http://rahuljadhav.tripod.com <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org...

The example in the documentation demonstrates using speex_bits_reset before encoding and decoding each frame. " speex_bits_reset(&bits); speex_encode(enc_state, input_frame, &bits); nbBytes = speex_bits_write(&bits, byte_ptr, MAX_NB_BYTES); " What happens if this is not done? I think I'm missing the point of having a SpeexBits object.

...way is probably to turn VAD *and* DTX on. Then when there's silence, the speex_encode function will return zero, which means you don't have to transmit the frame (normally, it returns 1). > Is it that during encoding speex_bits_write will return a lesser > number if the audio at byte_ptr contains silence? You could do it that way but you may run into problems at low bit-rate VBR modes, where the same mode can be used for silence or low-volume speech. Jean-Marc -- Jean-Marc Valin, M.Sc.A.

...cts nonspeech, the decoder inserts 'comfort noise', so that the end user doesn't suddenly hear a complete silence, but rather a continuation of the background noise.
