RECORDING HINTS -- written about using GarageBand -- BUT
these Hints help increase your skills in ProTools, Logic, etc.
It's a great way to add flute or "atmosphere" or other enhancements
to an older version of one of your songs if you don't have a BAND file for it.
BUT what often happens: a STRUGGLE
to make it the IMPORTED track align in timing with your GB click track.
Here are a couple of easy hints to try before you fret too much over the attempt:
1. First, you'll probably need to PUT SOME SPACE in front of the MP3 track.
So slide the track to the right, to add at least one measure of room.
2. Turn OFF the Snap to Grid feature (under Control menu item).
3. Now play the metronome with the track: Keep sliding the imported MP3 region
until it's as close as possible to the first count of the music hitting the first count of GB's metronome (also under Control).
Here's the TRICK for the Annoying Part that sometimes happens:
4. If it still is not quite "on" but you're having trouble hearing where count one comes in to match the MP3 and metronome, here's a cool hint:
--a-- Open the Notation View (the "snowflake" at the bottom left).
--b-- Click on the new MP3 track's NAME to select it. The WAV files of the MP3 will now be showing in the Notation view.
--c-- WithOUT the metronome on, play the MP3 track solo, and watch the peaks.
After a bit of time, you should be able to hear the timing of the music's first counts
and slide the track until the peak in the WAV file matches count 1,
This doesn't always work, but it usually does ...
or gets you much closer before trying something else in Garageband.
Note that the BIG PROGRAMS like ProTools & LOGIC have a SLIP feature that's more exact..
FINAL STEP for FINISHING UP:
STEP 5 finally: You have to get rid of that space in front of the audio track if you want to clean up your project. There are two main ways:
(1) split the region on a count 1 just before the music starts,
delete the unnecessary front region, and slide the 2nd region to the front of the track.
Ensure that Count 1 of the track lands with Count 1 of the metronome...
usually a bigger WAV peak there.
(2) Solo the audio track and send it to iTunes, bounce it, or whatever.
Then bring back the now-filled-in full track with the extra front space
into your project. Delete the old audio after you ensure everything is working right.
Much joy to you creating new music!
