Subject:Editing mp3 files in SF 6 Posted by: drbam Date:2/3/2003 7:20:56 PM This is the first time I've actually edited mp3 files in SF. I usually work with wav files then convert to whatever mp3 format I might need. Anyway I recorded some lecture tapes (cassette) into SF to clean them up and do some noise reduction on them. Since these are just for personal use, to save drive space I initially saved them as mp3 files and then began editing. I noticed that everytime I save ANY edit, I am prompted as if working with a brand new file, ie; naming the file again, and other property considerations. Obviously this incredibly tedious! Is this normal? Thanks, drbam

Every time you save to mp3, you are re-compressing the data, so we ask what compression parameters you want. The next version will be a little smarter about this, but still will not always be able to detect everything (like quality settings) from the file itself. Since mp3 is a lossy compression format, you're introducing compression artifacts on every save. So I'd highly recommend NOT using mp3 as an intermediate format. If you save a lot during a session or your edits require multiple sessions, save off a .wav version of the original first, do all your edits on that, then render to mp3 and delete the .wav when you are done. .wav saves will not pop the Save As, and will be optimized in many cases. As far as disk space, well, 6.0 always builds a proxy for mp3s (filename.mp3.sfap0) so editing a temporary .wav version is really no worse. Note that the proxies are not deleted by default so make sure to clean them out now and then, or check the "delete temporary files on close" pref. J.
