That's the idea: take telephone/voice @ what? 4kbps? -- it was
standard means between 300-3100Hz. often - sounds below 300Hz are now that
filtered today.
record your voice at 8Khz sampling rate and then compress with speex
various options and compare compressed and uncompressed.
If you're not an expert you should probably stick with one of the
--preset modes. E.g. '--preset medium' or '--preset standard'. That will
give you variable bitrate files with good quality.
lame -h -V 3 is what i use.
The speakers in telephones are tiny. That's probably a large part of it.
lame -h -b 96 - i was able to tell the difference on every song, but it
wasn't really huge deal.
hm. oh, yeah, my new box has to have a superior soundcard. and
i'll pony up for even better speakers too. (so when i'm ready,

For the same reason, you do not convert between lossy formats. Each might
give different kinds of artifacts that you do not want to combine. (Of

All of these are already compressed.
- The general archivers can compress the wav somewhat without loss, but
none do as well as the dedicated lossless compression program flac.
- Trying to compress mp3, ogg and flac files further is a waste of time.
- If you want smaller files, use lossy compression like mp3 or ogg
