I was asked by a friend to look at her son’s audio project he was doing. He’d asked me for advice and I’d given him my advice but she said he wasn’t happy with the final quality as it sounded terrible.
I got him to email me the finished mix down and it did sound awful so I asked him to send me a screenshot and straight away I saw the problem.
When adding effects in the effects rack Audition completes 1 before 2 and 2 before 3 etc. If you have your effects in the right order you can get some fantastic audio but if they’re in the wrong order you can get some terrible sounding audio.
The mistake he’d made was putting the noise gate in after he’d applied EQ and compression. The recording had picked up what I assume is the computer fan and the noise gate couldn’t then be set because the compression had boosted the volume of the background noise quite close to the volume of the speech so the softer parts were potentially going to be lost in the noise gating.
Fortunately, he’d kept the session file so I told him to move the noise gate to slot 1 and all of a sudden he got the audio he wanted.
That’s a drastic case but it’s always worth thinking of the order you add effects into the effects rack whether in multi-track where they’re totally non-destructive or in the wave editor where they do become destructive once applied. Never be afraid to question your order and check your order both audibly and in the preview and spectral frequency display before committing anything to edit destructive waveform editing or multi-track mixdown.
