In this walkthrough, we've shared how to edit in Adobe Audition, so you can make smart decisions about mixing, compression, and more.
Tips to Get You Started
- Generally, your audio should sit between -6dB and 0dB. This ensures that the audio is loud enough to be processed without losing fidelity, and quiet enough to avoid clipping.
- Reducing background noise in Audition is easy. Just drag over a quiet (i.e. no talking or music) section of the audio clip, right click, and choose "Capture Noise Print". This helps Audition to analyze the overall clip and locate the offending noise. Then, choose "Effects" > "Noise Reduction / Restoration" > "Noise Reduction (process)". Choose the "Select Entire File" button, and then click "Apply".
How to Edit in Adobe Audition
If you're working in another Adobe program like Premiere Pro, it's easy to import audio and perform quick edits in Audition. Just choose "Edit" > "Edit in Adobe Audition", and the clip will be rendered in Audition as an editable .wav. This is a copy of the original audio, so any edits you make are non-destructive.
This feature also works with audio sequences. Choose "Edit" > "Edit Sequence in Audition", and Premiere will copy the selected sequence as a rendered audio file. In the Edit in Adobe Audition dialog box, you can specify the audio selection, clip effects, track effects, and more.
Using a Compressor
To deal with variations in volume during an audio clip, you can add a compressor effect to make the volume more consistent. First, find the Effects Rack and click on the arrow next to the track that needs compression. From the list of effects, choose "Amplitude and Compression" > "Single-band Compressor".
Start by selecting a preset, and then tweak the various compression settings. Adjust the Threshold level until it's just above the average volume, so that it clamps down on the occasional peaks. For more extreme compression, you can raise the Ratio, so that every dB passing over the Threshold will be reduced by a larger amount.
Finally, you can adjust the Attack and Release to determine how long it takes for the Compressor to kick in, and then release. In many cases, the compression will reduce your track's overall volume. You may need to increase the Output Gain as a result.
Using a Limiter
If you need to reduce some unpleasant peaks in an audio track, but don't want to boost the overall volume, you can try a Hard Limiter. This effect is also found under the "Amplitude and Compression" category. Similar to Threshold, the Maximum Amplitude setting acts as a brick wall for your audio, and nothing will exceed it. However, any more than a few dB of limiting will have a negative effect on audio quality, so use it conservatively.
