pop noise in recording

Postby JannieM » Tue Jul 10, 2018 2:19 pm

Hi Everyone,

Today I tried recording some piano music and when it was played back there was a slight popping noise scattered through out the recording. This is the first time have seriously tried recording a piano but did research it on YouTube. However, I only have one dynamic mic to get the job done. But, I do use an interface with my computer.

1) Any ideas on what could be causing the popping noise?
2) Does anyone know how to get a popping sound out of a recording?

To remove the pop you need surgical audio editing plugins like iZotope RX 6 which has processes to remove the pops.

Why they happen in the first place:

1) computer underpowered and CPU is overloaded
2) audio buffer in your DAW is running at a small size and overloading CPU. The reverse of this is the buffer size is set too large and there is latency in the recording path making it impossible to play in time with a click track or other recorded tracks.
3) power supply to computer, audio interface, or anything else in recording path is "dirty" and causing the unit to have fluctuating voltage.
4) you have recorded with the preamp on your interface set too "hot" (high) and those pops are actual distorted notes. Digital recording has a fixed max volume.
5) if its something like a vocal, using a pop filter might help during the initial recording, but won't help a source like piano.
6) level in DAW is set too high so you channel meters are in the red and distortion is occurring in the mix portion or your DAW.

There could be other causes but these are some of the most frequent issues.

Good luck!

Thanks for your reply Andy. Guess I will start at #1 and work my way down the list until the problem is solved.

Just curious, for my own information, is a dynamic mic the best choice for recording acoustic piano?
