Just curious, any reason you're not using Speex for high quality (at
18.2 and 24.6 kbps, I can't distinguish the coded from the original and
15 kbps is pretty close)? I'm also not sure I see the idea of narrowband
PCM either, since you can get better quality at lower bit-rates by
encoding in wideband (16 kHz).
