Hi there. I am having a little trouble understanding the frame sizes chosen by the codec. testenc_uwb.c from the speex-1.0 source distribution has a framesize of 640 hardcoded and makes use of this value exclusively. However, a mode query on the actual codec returns 320 as a framesize for this mode. int tmp; speex_mode_query(&speex_uwb_mode, SPEEX_MODE_FRAME_SIZE, &tmp); <p>t...

Hi List, Now I will send to you more specific what I am trying to do. I have one Asterisk Channel where receives Midia Frames in the codecs format: Speex UltraWideBand and Speex NarrowBand. When I use Speex NarrowBand the Asterisk is able to convert this frame to G711. But when I use Speex UltraWideBand the Asterisk don't convert it. Then I need in my Asterisk Channel Source include the Speex

Hi all, I'm new to the group. I'm looking at the speex code with an eye towards maybe helping out with either codec optimization or fixed-point implementation, The SNR calculation in testenc.c and testenc_uwb.c doesn't make sense to me. The code is { float enoise=0, esig=0, snr; for (i=0;i<FRAME_SIZE;i++) { enoise+=(bak2[i]-input[i])*(bak2[i]-input[i]); esig += bak2[i]*bak2[i]; } snr = 10*log10((esig+1)/(enoise+1));...

...that call. Anyway, it's now fixed in CVS (both trunk and 1.0.x branch). Thanks for the bug report.

...is works fine. But when I try to encode speex, and decode it, it works, but some high frequency noise is added. How can I fix it? The noise isn't the microphone <-> speaker positive feedback, cause it doesn't appear when not using speex. I think it's almost the same as your testenc_uwb.c included in speex distribution, but mine maybe something wrong... Source code is here. http://maaash.jp/lab/speex/main.cpp and Windows binaries here. http://maaash.jp/lab/speex/speexecho.zip There's a switch to enable speex in main.cpp #define USE_SPEEX Thanks in advance!

The resampler will convert raw audio from one sample rate to another. You are starting with Speex-encoded audio frames. So, what you need to do is: 1. Run the media frames through the Speex decoder (look at Speexdec or testenc_uwb). This will give you raw audio with a 32 KHz sample rate. 2. Use the resampler to convert the audio from 32 KHz to 8 KHz sample rate. 3. Run the 8KHz audio through a G711 encoder. For the narrowband case, Asterisk is doing steps 1 and 3. ----- Original Message ----- From: Thiago Maluf T...

...the voice quality seems to be better comparing to 32 KHz. 2) When I use wideband mode with 16 KHz sampling rate bandwidth usage is greater comparing to 32 KHz, ultra-wideband. Why? Voice quality is worse when using 16KHz wideband comparing to ultra-wideband coding. 3) Speex samples testenc_wb and testenc_uwb gets SPEEX_GET_LOOKAHEAD parameter and skip appropriate number of samples. Should I do the same in VoIP ? What this value means and how is it used in Speex? 4) If sampling rate is 44100 and I use wideband (not ultra) coding bandwidth usage is very high (about 9 KB/sec). Is it normal and just happe...
