So I have a home studio set up, got everything i needed, so i can record my own podcast n vocals n everything right?


As the title says my audio has a annoying amount of “white noise” when i record. Its not from my room as i have moved to a different room with a better sound. It sounds like its the Self noise from the mic or noise floor from my interface. Is there anyway to remove this self noise completely or am i just chasing something that doesn’t exist?

My gear:

XLR to XLR UMC202HD BM-800 Condenser

Macbook Air

  • Is phantom power on, & have you confirmed it's being received by testing on & off? [don't switch with the inputs live, of course] Also have you checked your gain staging for optimum levels at input? I've tested one of these mics, & while it won't win any prizes, it's not hideously noisy. – Tetsujin Oct 3 '18 at 18:35

UMC202D is reasonable (its weakness being a whine from the phantom power supply but that does not sound like white noise), BM800 is low quality. For podcasting, its noise level should not be much of an issue but you would want it switched off while playing music etc.

But for it not to be much of an issue, you need to use correct gain staging: dial up the gain on the audio interface such that it does safely not overdrive (sth like -10dBFS tends to be reasonable) but not lower than that. Speak into the mic at a reasonably close distance (this may warrant using a pop filter, also because electret condenser capsuled don't really fancy humidity) and into the correct, marked side.

You can use a multiband compressor (or dynamics processor I guess) to filter out only unwanted frequency bands when the volume is beneath a certain threshold. This will leave most of the recorded content unaltered depending on where the noise is sitting (in the frequency spectrum). I've had great results. Always try and get the recordings as close to 0db as possible this way you will leave the noise floor further behind and easier to filter out.

The actual answer to your question is no you cannot remove the noise completely (in the original recording).

  • No. Don't try to remove the noise, avoid recording it in the first place. You doubtless have a gain staging issue. – Laurence Payne Aug 29 '19 at 14:20
