Mastering Process: (4) Limiting

 

A limiter is basically a compressor with a high ratio. Inserting a limiter on the master fader will help to boost the overall volume of the stereo mix without going into distortion. There are some very sophisticated hardware and software limiters that allow you to setup parameters such as"Look-ahead" and individual Gain for the Left and Right channels. More basic limiters are based on the same setting you would find in a compressor but with a fixed Ratio, usually set to its maximum level as default.

 

 

1) Insert a Limiter into the Master channel of the Mix window and apply the settings shown in Figure 1.

(In this article, I am dealing with the 'Compressor / Limiter' in Pro Tools. See the Figure 1 below.)

2) Make sure that your mastered Mix does not clip.

Usually a 2 or 3 dB reduction to the Master fader is applied when preparing a mix for any low bandwidth perceptual encoding session. Because of the nature of the encoding process, those encoded files (e.g. YouTube, QuickTime audio files) tend to have less headroom and therefore tend to distort the high frequencies even when a regular PCM mix sounds fine. It depends mainly on the content of the audio that is encoded. If you experience any distortion in the final encoded audio file, you will have to reduce the level of your Master fader and encode the mix again.
