Compression and MP3 players
« on: 24 Nov '06 - 20:10 »
I've been thinking about how I compress music for my MP3 player, and thought you guys might have some ideas about this.

Currently I use 25% quality WMA (latest version), at 44.1kHz stereo. I used to use 64kbps vbr WMA, but decided that was too low - 25% quality generally throws out about 90kbps.

I have thought about using MP3 for it instead of WMA, but I have no idea what's good at encoding low bitrate. OGG, ACC and the like are out of the question as my player doesn't support them (and no, I'm not buying a new one).

The sources are generally either 44.1kHz q6 OGG or modules, and it'll generally be used in comparatively noisy environments with earphones (Seinheiser MX350).

Anyway, suggestions? Recommended codec/program/settings? I'm reasonably happy with what I've got, but you can never fit enough music on these things and something to eke out another hour or so would be nice.

If you want to achieve the same sound quality with MP3 as with WMA, the bitrate will be a lot higher. 90 kbps WMA isn't that bad if you just want to listen to it and don't make cd's out of it :). If you want more quality, you could try two-pass vbr, but it won't add that much ;).
I prefer to use dBPowerAmp, but the two-pass thing is only 30 days with that...

I thought that might be the case. I could try dropping the sample rate down to 22.05kHz, but I doubt that'd achieve much. Ah well, I'll keep on with the WMA then. Here's hoping Creative will add OGG support for their MuVo TX!
