Speex in flash player: how to work with?
Nicer way:
void* speexState = speex_encoder_init(&speex_wb_mode);
int speexFrameSize, speexRate;
speex_encoder_ctl(speexState, SPEEX_GET_FRAME_SIZE, &speexFrameSize);
speex_encoder_ctl(speexState, SPEEX_GET_SAMPLING_RATE, &speexRate);
SpeexPreprocessState* speexPreprocessState = speex_preprocess_state_init(speexFr...

speex corrupting input buffer?
...is
related to a high pitched sound I'm getting after decoding since I get
a similar sound if I just play the corrupted input buffer.
Thanks,
Steve

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/

High CPU usage
Hi Mark,
Code below:
int16_t* samples;
int16_t* fbSilenceFrame;
void *fSpeexState;
float eng(0.f);
int speexFrameSize(0);
speex_encoder_ctl(speexState, SPEEX_GET_FRAME_SIZE, &speexFrameSize);
for (int i = 0; i < speexFrameSize; i++)
{
eng += samples[i] * samples[i];
}
if (eng / speexFrameSize < 3.f)
{
memcpy(samples, silenceFrame, speexFrameSize * sizeof(int16...
