Learn about the function of the controls in an AudioSuite plugin window, using the Normalize plugin as an example.
- [Instructor] AudioSuite plug-ins provide an alternative to real time plug-ins for audio processing. Rather than applying changes during playback, AudioSuite plug-ins apply file based changes creating clips that have the plug-in processing written in. For this reason AudioSuite plug-ins are considered non-real time processors. To demonstrate how AudioSuite processing works I've prepared a couple of clips at the start of the session that play backwards. I'll use an AudioSuite plug-in to reverse the clips. Here's how it currently sounds.
(reversed mellow rock music) Okay, so now I'll select both clips and use the reverse AudioSuite plug-in to get them to play forward again. Now your AudioSuite menu may not have all these choices in it, but the reverse plug-in comes with Pro Tools so you should see that one regardless of what other plug-ins you might have installed.
This plug-in is an example of an AudioSuite only plug-in. The reverse function is not available as a real time plug-in as it requires re-writing the audio. Many other plug-ins are available in both real time and AudioSuite formats such as EQs, reverbs, delays, and so forth. AudioSuite plug-ins use non-destructive processing by default meaning that they create new files on disk leaving any original audio intact. In the processing output mode selector here, I can choose how I want the plug-in to render the results.
The reverse plug-in allows me to create individual files which will generate separate output files for each of the originally selected clips or to create a continuous file which will generate a single combined file for the output. Many AudioSuite processors also provide the option to overwrite files and this option is destructive, meaning it writes the changes directly into the parent file on disk permanently altering its contents. The overwrite files option should be used with caution since the parent file could potentially be used in other sessions as well.
To the right of the processing output mode selector os the processing input mode selector. And here I can select how I want the plug-in to process the incoming clips. I can choose to process the clips one by one or to process the entire selection. In the reverse plug-in the input and output selectors are linked so processing the input using clip by clip will always result in individual files at the output while processing the entire selection will always result in a continuous file at the output.
So let's take a look at the difference between these options. For starters, I'll select clip by clip for the input mode and render that. So now I have two separate clips that have each been reversed in place and let's hear the result. (mellow rock music) All right, so now let's undo that. And this time I'll render the entire selection.
The result is a single continuous clip and let's listen to that. (mellow rock music) So this demonstrates the effects of those settings. Not only did the output mode generate a single clip, but the audio was also processed as a whole reversing the entire selection rather than processing each clip and reversing it individually. So there are a couple of other points I want to cover regarding AudioSuite processing.
The first is about the use in playlist option here. In most cases you will probably use the newly processed audio on the track where the original audio was, but at times you may want to process audio for use elsewhere. So let's say that I want to grab the tail end of this line and apply a unique delay treatment for use at the end of the session. I'll select a sufficient length for the delay tails that I want. And I'll use the mod delay two plug-in for this, which I can choose from this selector without having to close and reopen the AudioSuite plug-in window.
And here I'll set this to use mono mode and move it over here so we can see what is happening. I'll set this to a quarter note delay time with a 50%-60% feedback, somethin' around here. And I'll bring the mix down to about 35%. Somewhere in there is fine. If I leave the use in playlist option on, the processed clip will replace the audio on the track.
But that's not what I want, so I'll undo and turn use in playlist off up here. And now when I click render the result will be placed in the clip list where I can access it for use later. The other thing I want to mention is the affect of the setting here which defaults to 2.00. This value is the AudioSuite handle length. Using AudioSuite handles causes a portion of the underlying audio form the original file to be included in the processed result, enabling you to trim or cross fade the result later if needed.
The default value uses two second handles, but you can change that setting as needed. Simply click and type in a different value. If the whole file option is available here you can optionally include the entire underlying file in the processed result. So those are the primary controls you need to be aware of for AudioSuite processing. Set the processing output mode on the left of the window and set the processing input mode on the right. Set the plug-in parameters in the bottom portion of the window if applicable.
Enable the use in playlist option to render the results in place on the track and disable it to place your rendered clip in the clip list for later use. And pay special attention to the AudioSuite handle length setting as this can also impact your results.
