Drum Editing with Beat Detective and Elastic Audio for $75
If you have recorded live drums to a click and you want to get them to be perfect, so you can easily fly and loop sections around. and do overdubs knowing that the timing is perfect. You might want to consider whats called in the industry "chopping drums"
This Process splices every drum hit, and then lines them up to the click.
If you did not record to a click, but you want to fix a few timing issues, Elastic Audio can work to stretch timing around to fix an odd drum fill, or hiccup in the groove.
