Put All Audio Questions Here

As LiquidAcid brought forth, -q 5 should be ideal to get a great sound with a moderate filesize. It is the setting Hydrogenaudio recommends to achieve transparency (no perceivable quality loss), so using a higher setting is somewhat pointless for standard listening purpose.

Since you'll be transcoding from MP3, there will be additional quality loss. If your goal is to get excellent audio quality, you might want to try a higher setting and verify if there would be any difference. But I think going with -q 5 should be good enough. On the other hand, if space limitations would be problematic, you could also use a lower setting. If you're uncertain, do some tests with the different settings and find out which would suit your needs best!

Jam it back in, in the dark.
