Title: 60 cycle "heartbeat" static sound in recording - how to isolate and remove?
Post by: cj.flac on June 30, 2026, 03:08:13 PM
I have a Tascam DR-40X that I ought to throw in the trash.

Yesterday, I used it in place of my Deity PR-2.
(The Deity's thin plastic inner casing around the battery has cracked, making the positive terminal for one of the battery slots loose and warm to the touch. I may contact Deity for warranty coverage).

The last few times I have tried recording with it, it's introduced a static "ticking" sound pervasive throughout. It's probably emanating from the screen ticking off the seconds. Even if I were to troubleshoot this by setting the screen to turn off after a certain amount of time, that shouldn't be an issue on a field recorder at all, so that's something to contact Tascam support about, too.

In the meantime, here's a sample (https://vocaroo.com/1izORyh8bQpR) of what this sounds like. How would I approach removing or mitigating this in something like iZotope?
