Hi, In another DAW there is a command called "trim" that given no audio selection will "strip silence" off of the start and finish of a file _only_. This is extremely useful for when you have just recorded an external synth sequenced with midi and know that the relative timing between the notes are correct, but where the clip starts isn't due to midi and/or audio card latency. Once the silence is cut off of the front of the file you can snap it to it's position and the timing will be on. I know about strip silence. From what I understand this will affect the whole audio file, breaking it into regions based on the threshold and parameters. I only want to "strip silence" for the silence at the start of the file. Using the marquee tool with smart on seems to do an "ok" job of this, but that tool always seems suspicious to me, like i'm not sure what i'm going to get. Is there a simple way to do this in Logic? Thanks, -- Ben Harrison http://mumble.sectionz.com

Strip silence on the whole file, then glue tool or keycommand.

Depending on the file you're working with, sometimes dragging the Threshold percentage up or down will yield the desired results, or something very close. If you get a start point you're happy with there, you can always "Replace" the region with the stripped regions, delete the regions after the first one, and drag the end of the first region out to the end of the song again. Not quite as easy as that other DAW, but effective nonetheless. Sonny Keyes SKa Music Toronto www.skamusic.ca

It manages to strip the silence off of the front but then obviously breaks up the audio file based on the threshold. When using the glue tool after that it performs a stereo mixdown on the regions and actually writes a new audio file. This seems overly destructive for just wanting to trim the silence off the front of a file. Or maybe it isn't that bad for the audio... i'm not sure. I have peak too. I haven't looked into whether it can do this yet but it sure would be nice to do it from the arrange instead. A command like this would be great for synth musicians making quantized electronic. FL Studio (fruityloops) is the app that has it! This came up after a discussion with an owner of that program where I proudly told him about all the latency measuring I had gone through to assure my timing was correct. He said "I just use trim and snap the audio into place." :-/ Well gee.... Not that I want to use FL... but it's a $49 program and it bugs me when it does something easier than my $999 program. :-) -- Ben Harrison

It's simpler than that. Strip silence so it trims start/end to your satisfaction. Ignore the mess it's making in between. Replace. After strip silence, all the new regions will be selected. Just click with the glue tool. You're done!

Really? It doesn't here (L7), if nothing has actually moved, it just fills the gaps in again. Sure you didn't move anything after stripping silence?

Thanks to everyone who posted suggestions. I have about 3 different ways to do this now. -- Ben Harrison
