Freezy Freakies  [ Edit ] 

The latest good Logic question (courtesy of Victor from Virtual Turntable) dealt with how to bounce multiple tracks as separate files. This is useful for sending your project from your Logic setup to another studio that doesn’t use it.

This was a great question to figure out because I’m going to have to bounce a lot of stuff for the album I’m working on right now. I’m programming drums for twelve songs, and will have to do a lot of bouncing to get the audio into the producer’s Digital Performer setup.

It may look impossible, but it isn’t. Just Freeze the tracks.

emagic talks about this feature mostly in the context of helping older computers, like mine, deal with lots of tracks with lots of plugins. Because Logic doesn’t prerenders plugins (I don’t think any modern DAW software does), instead rendering the effects in realtime as you play or record sound, your old computer can quickly slow down under the stress.

When freezing a track, Logic runs through your song from beginning to end, prerendering all the effects you’ve applied to the track, and creating a regular audio file that represents the final sound. Audio files are totally inexpensive for Logic to playback (limited by your disk speed), so freeze can help you develop a song with virtually unlimited effects.

To do it, you just click the little snowflake button on your track, and press play. How fast the files are rendered depends on your machine, but once it’s done, you’re good to go. The freeze files are saved in a folder called “Freeze Files” in the same folder as the song you’re working on.

This is great stuff. Each track has its own freeze file. They’re cryptically named, but they’re all there.

I haven’t experimented with this fully, but the main drawback I see here is the inability to set the format of the freeze files. There may be a way to control it, but I don’t know what it is. I’d like to specify the format (AIFF, WAVE, or SDII — mp3 isn’t useful for Freeze) and stereo setup (interleaved vs. split) like you can with a regular bounce.

Because I don’t have that control, Freeze is less useful to me right now. Digital Performer uses SDII files, which I can’t freeze directly, and the producer also wants dual-mono, or split stereo, files. So I may do this freeze and convert the formats afterward. We’ll see.

Freeze is still cool, though.
