To choose how the audio plays in your presentation, select an option: When Clicked On: Plays audio only when the icon is clicked on. In Click Sequence: Plays the audio file automatically with a click.Īutomatically: Plays automatically once you advance to the slide that the audio file is on. To choose how the audio file starts, select the dropdown arrow and select an option:

To adjust volume, select Volume and select the setting you prefer. To fade in or fade out audio, change the number in the Fade Duration boxes. To trim the audio, select Trim and then use the red and green sliders to trim the audio file accordingly. Then select which options you'd like to use: Select the audio icon and then select the Audio Tools Playback tab. If you’re using more than one audio file per slide, we recommend putting the audio icon in the same spot on a slide to find it easily. To move your clip, select and drag the audio icon to where you want it on the slide. Select Record to re-record your clip, or select OK if you're satisfied. To review your recording, select Stop and then select Play. I'd go with SoundSource over Audio Hijack by far.Note: Your device must have a microphone enabled in order to record audio. Update SoundSource overdrive is working for me now on an 2021 M1 MBP, for master output level and per-app as well. Sound Source can supposedly overdrive audio for applications as well, but I have not noticed an increase in volume when I've tried it, I still use it though as it is a really convenient input/output selector than the Mac OS, and it has the advantage that you can control volume for each application independently. Not necessary but I use Audio Hijack in conjunction with Loopback to easily select audio sources I want/don't want as my input audio. Your input or output device or application names may vary. Below is an animated demonstration to show the essentail blocks you'll need to add to overdrive your audio and start a session.

I suggest using 3x or 4x with great care turning system audio very low and then bringing it back up to a comfortable level after starting the session and selecting 3x or 4x to avoid blowing out the drivers on your earphone/speakers etc.

Be warned, I have blown out a pair of earphones using this. This has been the only thing I've found that actually makes the volume louder using software rather than just distorting the audio. Select your Output Device (speakers, earphones, etc), and then start the session. Options are: Off (no overdrive/100% volume), 2x, 3x, or 4x. To achieve your goal, Add your sound input(s) (Input Device, or Application) and then add an Overdrive function. You don't have to record if you don't want to. It's a digital recorder with a real-time audio effects engine. Audio Hijack by Rogue Amoeba can legitimately overdrive your audio, among other things.
