Hi all,
Ok, here's the simple situation.

I ripped some tracks for a new CD. One of the tracks has this intro that I really don't want so I thought I'd use iTunes to start the track at 1:38.755. Turns out, iTunes doesn't acutally start with a time smaller than .1 second. Ok, fine. So I fire up Quicktime Pro and use the editor to edit the .aif file. Sorry, QT Pro only allows you to move the cursor 0.07 seconds each time you press the arrow keys. I got the file edited down to what I want, except now I need to trim like 0.02 seconds off of it. There's a very distracting noise in the beginning and I just want to clean it up. Any ideas? Thanks.

Mike

Perhaps not the simplest of solutions in the short term, but Digidesign has a free version of their Pro Tools audio editing software available at www.digidesign.com. You can edit with sample accuracy.

You can also edit audio with frame accuracy in iMovie or FCP but that will only get you down to about .0333 second.

don't forget spark ME for OS X. it's free, and is strictly audio editing, not like PT Free (which may be too much for what you want to do).

This is a down and dirty way of getting rid the unwanted sound.

Use the following SMIL file to trim the beginning of your sound. Enter the start time on clip-begin (line 13 - which I've already done) and enter the clip-end time for the track. Replace the audio file name at the beginning of that line "your_audio.mp3". Save this text file with .smi file extension. Open QT > Open Movie in New Player (select the .smi file)>Save As > Self Contained.

I should have put quote marks around the word - trim - because it doesn't actually remove that part of the audio, it just won't play it.

BTW, it'll play fine in iTunes, but it won't list a track time.
