Join Garrick Chow for an in-depth discussion in this video Automating volume with the Envelope tool and Auto Duck, part of Learning Audacity (2012).
In this movie, I want to take a look at the Envelope Tool, which is used for smoothly…controlling a track's volume level overtime.…I'm still working with My Podcast Project file and if you recall I added this stereo…music track earlier.…I've had it muted up to this point since we've been working with the other vocal tracks, and…if I un-mute that and play a little bit back we'll see that the music is still too loud right now.…(music playing)…Now it's not uncommon to have music playing in the background during a spoken word recording,…you hear this a lot in news reports on the radio.…
Now I could simply lower the volume of the music track, and we can hear how that sounds.…(audio playing)…That doesn't sound bad but it does make that entire music track one consistent volume.…Let's drag back to 0 dB.…So what I'm going to show you here is how you can get a much more professional sounding…result by automating the volume level to have the music get louder when there's no talking…and to get quieter when there is talking.…
