Hi, Does someone know if I could use SpeexPreprocessState::loudness or SpeexPreprocessState::loudness2 to create a VU meter. And if so, how? <p>Thanks, Tom Moers --- >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@xip...

Hi The latest SVN trunk for speex has changed the SpeexPreprocessState to an opaque structure, for jolly good software engineering reasons. However, the Analogue AGC (AAGC) feature of iaxclient (in audio_enode.c) relies on some members of this. It uses speech_prob to detect when there is enough speech to consider AAGC and then loudness2 to decide how to adjust the...

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. For more information, please see ActionScript 3 reference http://help.adobe.com/en_US/AS3LCR/Flash_10.0/ Jozsef

...n a proper way? do i need to deal with the delay between the sound being registered by the microphone and the one going out of the speakers? (i don't know you anderstand what i mean, sorry for my poor english) also, there is an echo parameter to the preprocess function : int speex_preprocess(SpeexPreprocessState *st, short *x, int *echo); do i need to provide to it my cancelledSpectrum variable? best regards, fredo -- No virus found in this outgoing message.
