Mastering Advice
« on: December 27, 2018, 06:59:47 PM »
I'm hesitant asking this as I don't want to sound like a noob and/or buffoon. So here it goes ...

I'm working on a show that was sent me and I am hearing some weird "phasing-like" issue where it sounds like the wav file is normal and the lowered and then raised again ... so I'm thinking that some sort of limiter or auto leveling was used on the recorder.  I know that this description is VERY VAGUE (I apologize), any ideas as to where to start in fixing this issue? I use Audition and iZotope Rx7.

Sounds to me like something recorded with an "auto gain" setting in which the volume is automatically raised and lowered in response to volume changes.

You'd have to do painstaking enveloping. Find and mark every level change, then add or reduce gain to compensate.

Unless you're being paid by the hour, it isn't worth trying to fix.

I was thinking the same thing, my fears confirmed. Lol.

That is a tough situation to solve. Automatic gain adjustments, and especially limiting, not only change the level but also reduce the dynamic range. You may be able to get a bit of dynamics back by using upward expansion.

Here is a great resource guide that may help understand the processes: https://www.soundonsound.com/techniques/parallel-compression

Thank you for the link ... I'm trying some of the recommendations. Fingers crossed!

Thank you again for this. I was able to (somewhat) successfully fix some of the issues using the guidelines and techniques in the link you sent. Very eye opening (or should I say "ears") to learn a new trick or two!
