If your audio is overloading the Master Output in Sunday Mix for Logic Pro you'll want to review Video 12: How to Use Mastering Tools in the video or the steps below:
Sunday Mix for Logic includes some easy-to-use mastering tools to help you add a final gloss to your session, and achieve proper levels for streaming platforms if you plan on streaming or posting your recorded service.
If you click on the “Master Output” track, you’ll see the description of these tools and what they do in the Note pad. Both of these tools are bypassed by default, so you’ll want to turn them on before adjusting any parameters. You’ll find most of your Mastering Tools available to you in the Smart Controls window. However, the Loudness Meter Plug-in is only useful if you open it up from the Inspector or Mixer window.
To Master a session, there are a lot of details to be considered. The primary goal when mastering is to add the final glue to the session, and bring the overall level up to the standard for which you plan on using it. That’s why we’ve included these two simple tools to help you do so.
To begin, you’ll want to gently compress your audio so that the quieter parts of the service are just as audible as the louder parts. By increasing the Gain level, you bring the sound floor up, while leaving the loudest peak at the same point. You can also adjust the output ceiling if you wish for the loudest point to be higher or lower.
Next you’ll want to see exactly how loud the audio is by using the universal Loudness scale, LUFS, which stands for Loudness Units Full Scale. Most streaming platforms consider the ideal loudness meter reading to be -14 LUFS. To properly use the Loudness Meter, move your cursor to the beginning of the session, open the Loudness Meter Plug-in, and play through the entire session without adjusting anything. This will give you the overall loudness reading of your entire session. You should aim for -14 LUFS. If your reading is too high or low, adjust the Adaptive Limiter parameters and play through the session again.
