Annoying audio click added to end (and sometimes start) of audio

I'm a voiceover artist who does a lot of eLearning narration. One client has a particular requirement of audio files split by file name, with 150ms of silence added to start and end of each file.

 

I have a favourite called 'add 150ms' of silence and after I've split the files I batch process the files by dropping into the batch process window and running my favourite. Works great - HOWEVER sometimes audition adds an audible click to the end (and sometimes the start) of the file.

 

As it's not constant I therefore have to go through each file and check the start and end of each file to ensure the click isn't there and using auto-repair keyboard shortcut to remove.


Given the inability to navigate the files area with the cursor keys, it means I have to go through EACH file by double clicking - which is a ball-ache.

 

Why does audition add this click sometimes? Picture added to help explanation.

 

The 'add 150ms of silence' shortcut is shown in screenshots...

 

Using macOS Ventura 13.4, Neumann TLM103 microphone and Audient ID14 interface.

Almost certainly zero-crossing errors, if it's random. If you join silence to either the start or end of a recording, and that start or end's waveform isn't at what's called a 'zero crossing' - which is where the waveform passes though the zero point between a positive and negative, you'll get a click which is generally full bandwidth (yours are) where the waveform trys to jump instantaneously from zero to whatever the start or end point is on the waveform - which it can't do.

 

Fortunately the cure is simple. Right-click on the timeline, select Snapping, and then select 'Snap to Zero Crossings. Doesn't particularly matter what other settings you have in it - that's the important one. And make sure that snapping is enabled. Now, when you make a selection, the ends of it will always be at a xero crossing - so joining silence to it shouldn't cause a click.
