In which Ian probably goes too far with his analogy explaining compression using sponges. And in which Jon describes the concept of “sloppage headroom” and inter-sample peaks, and in which we also discuss:
- Why lossy data compression doesn’t affect dynamics, except
- When it does. And
- Why dynamic compression doesn’t affect lossy compression quality, except
- When it does. Plus
- mp3 or AAC ? VBR or CBR ? Do we care ?
- The ultimate mp3 encoder stress-test
