Indeed, the chorus/aliasing effect is as good as gone with --no-peaklock, but the vocals begin to suffer from periodic amplitude modulation (tremolo). The effect even becomes a bit stronger with --crispness 5. >I perhaps foolishly didn't include a standard crispness option that only >does the equivalent of --no-peaklock, because that wasn't preferred to >any of the alternatives for the examples in my informal blind listening >tests.

At what stretching/compressing ratios have you run your tests, and with what kind of source material? While the code is certainly doing quite fine, I have a feeling that my 2x test runs could be a bit out of line with the intended kind of use.
