Recommended version for production use
...1.0.
Even without using any of the new 1.1 features such as AGC or denoising,
files encoded with the 1.1.11/1.1.12 speexenc.exe tend to contain wild
amplitude-level variations, tonal artifacts, and clipped regions.
Here's a good example of what I'm talking about:
speexenc --bitrate 7500 pcm16k.wav speex.spx
speexdec speex.spx recovered.wav
If you run these commands with the file
http://www.speakeasy.net/~jmiles1/pcm16k.wav in 1.0.4, the recovered.wav
output doesn't sound too bad. Under 1.1.11, the recovered audio sounds
terrible by comparison.
So: what are peoples' thoughts on...
