In this video I show you how checking the option, “Treat Mono As Dual Mono” when setting LUFS levels in Audacity will actually reduce your exported file’s level by 3dB. This option is there to meet the EBU’s broadcast standard for LUFS when working with a dual-mono track. A dual-mono track is a track with left and right channels (similar to a true stereo track) but unlike a stereo track, the audio in each channel is identical. But when used on a mono track, this option reduces the LUFS level by 3dB. As I show you in this video, if you’re exporting a mono podcast at -19dB LUFS with this option checked, you’re actually exporting at -22dB LUFS. This is important information.
In this video I show you how to trim the precise length of room tone that is required by ACX at both the beginning of your recorded waveform and at the end, using the Selection toolbar in Audacity. ACX requires 0.5 to 1 second of room tone at the beginning of your recorded chapter and 1-5 seconds at the end of each chapter. Using the selection toolbar to trim the excess audio gives you a precise way to be consistent with your recordings from chapter-to-chapter while meeting the ACX standard.

Let’s talk Audacity sample rates and bit depth. What is a sample rate? What am I sampling and why? What is bit depth? What’s the relationship between sample rate and bit depth? Why are there sample rates displayed in each track and a project sample rate in the lower left corner of the screen? What’s the difference and do they have to match? Where do I set the default sample rate in Audacity?

Now that the time shift tool is no longer a part of Audacity, how do we move audio segments? With the advent of Audacity version 3.1.x moving audio around has gotten easier and quicker. In this video, I show you how to split audio into separate segments, how to join audio segments together, and how to move audio now that the time shift tool is no longer with us.

I’ve found a problem with Audacity 3.1.2 that may be related to the Mac operating system. I can’t change or delete clip names (these are the new clip names that were introduced in version 3.1.0) and to make matters worse, if I try to do so with sync-lock tracks enabled, Audacity crashes every time. Someone on the Audacity User’s Forum mentioned they weren’t having that problem running Windows, so it may just be Mac related. I’m running MacOS Monterey (12.0.1) on a 2017 MacBook Pro.
