[Speex-dev] uwb bitrates

[Konrad Blum]

Hi,

With regards to adding 1.8 kbps to the bit rates in the wideband table 
to get the respective ultra-wideband bit rates, this words for all the 
bit rates I tested except the lowest. Adding 1.8 kbps to 3950 bps should 
give 5750 bps, but the encoder reports 4150. The encoder reports the 
expected rate for all other bit rates that I tested, eg: 5750 + 1800 = 
7750. I am using the (recommended) current unstable release (v1.2rc1). 
Is this behaviour as it should be?

$ ./speexenc --version
speexenc (Speex encoder) version 1.2rc1 (compiled Sep  8 2009)

$ ./speexenc --ultra-wideband --bitrate 5750 -V tmp.wav out.spx
Encoding 32000 Hz audio using ultra-wideband (sub-band CELP) mode (mono)
Bitrate is use: 4150 bps

$ ./speexenc --ultra-wideband --bitrate 7750 -V tmp.wav out.spx
Encoding 32000 Hz audio using ultra-wideband (sub-band CELP) mode (mono)
Bitrate is use: 7550 bps
