Using Soundtrack Pro as a Batch Processor

While Soundtrack Pro is only available in the current boxed version of Logic Studio, it is still a useful audio editor to use! David Earl (aka sflogicninja) shows how to use it as a batch processor.  

Soundtrack Pro is one of the most powerful and under-utilized apps in the Logic Studio suite. Many folks who open it up for the first time think that Soundtrack Pro may be redundant, since Logic is going to be the go-to tool for multitrack audio production.

Soundtrack Pro started off as a post-production tool in the film industry. Not only does it have a very capable multitrack audio editing and mixing system, it has a phenomenal 2-track audio editor as well. I liken it to '

Hi Miloslav

Yes, perhaps we could've mentioned that STP will process audio files in this way in a destructive manner (i.e. altering the original file) and therefore, of course, it is always important to make a copy of the audio file if you wish to keep the original intact.

However, the article in your link is describing the process of applying noise reduction which assumes you'll be tempted to work on the original file. Indeed, in that situation, you really should be making backups of your audio file first or exporting to a new file from within STP.

You could actually build in a number of automator actions/scripts to duplicate the original file first before one of the copies gets processed in STP.

Hey there!

With hard drive space being less expensive as the years roll by, I highly recommend that all audio to be batch processed should be copied to a new folder before processing.

As for the linked article, I understand Larry's concerns regarding the source audio being effected without chance of undo, but copying the folder is pretty quick and painless for even the largest audio project.

For noise reduction, I would create separate folders for different recording environments. These environments would have their own individual noise prints, given that the location audio includes room tone. This means separate scripts for different environments. I need to do a bit of research to see if noise prints are included in scripts. You cannot use the same noise print on very environment.

Each folder would be batched individually. Noise reduction can be tricky, due to potential volume fluctuations that may increase artifacts in the noise reduction. This is why having copies of the files is important.

I think Larry is right in saying that the best result would be to process individual files. I also know production schedules, and sometimes speed trumps quality depending on the project.

Also, all projects should be backed up either by using Time Machine or a program like Chronosync. This way if you have screwed up the original audio, it can be replaced with an original very easily.

Hallo David,
Hallo Rounik,

Thanks for reading and solution.

Excellent tutorial. Soundtrack has some amazing effects and processors which I wish Logic will incorporate. Hopefully in Logic X?
