Dialogue not loud enough for your film or video project? Using Adobe Audition? Good news! In the 2015.1 release of Audition, Adobe added a true peak limiter! This means that you can use the “match loudness” panel to make your dialogue audio loud enough and at the same time, not worry about the audio peaks clipping and distorting.
This is a great little timesaving feature. Thank you Adobe!
https://youtu.be/L1FLali0xLk We’ve done a lot of tutorials on processing audio and sound with Adobe Audition but many have asked how to do the same things in Audacity, which is, of course, free. The trick with Audacity is that it lacks certain features that can be critical for getting consistent results, namely, loudness processing and metering tools. But when you’re first starting, you may not yet have the budget for an Adobe Creative Cloud subscription. So if I were in that situation, here is how I would use Audacity to sort of accomplish the same thing (though not as consistently). Make your dialogue audio louder (without being too loud).
You can download and use Audacity for free - no strings attached, its open-source.
