Voicemeeter Banana humm

[RFU]

I tried installing voicemeeter banana on my broadcast system and never got it to work. I think the video I watched on Youtube skipped some steps.

So, now I'm using my old laptop as a "production" machine. Creating tags, sound files, etc and I decided to use it as a testbed for voicemeter banana.

The system has one external USB sound card with built in volume and mute controls and I was using headphones with a microphone

Playing a track through voicemeter banana doesn't seem to be a problem, but when I activate the mic I get a background buzz. It's not feedback because i'm using headphones.

Anyone have any idea why this is happening? If it's because the input and output are the same sound card, I can add another usb sound card and split it.

The hummm is most likely bad cables or cheap microphone. It has allways something to do with powerlines near the microphone cable. So first, try to move the powerlines away from the micro cable. If you have to cross, it sounds wierd but cross them at 90 degrees. Make sure that your earth connections are from the same outlet or central earthing point.

USB power is notoriously noisy. Thats by design really, the standard doesn't call for much filtering as most peripherals aren't particularly fussy about power quality - except audio equipment.

Quick fix would be to move your USB sound card to an externally powered hub. Make sure the hub has a decent power supply - look for certification stickers, known good brands etc.

ALWAYS spend the extra for shielded USB cables when using them in audio applications. Shielded cables eliminate humming issues. Cheap ass dollar store cables are just begging for poor audio quality.

This is true at some point. USB is digital signal so when you hear a hummm, it is picked up by the mic, encoded to digital signal and decoded by the computer. GSM, WiFi, Fluor light, switching power supps, all of those can give a humm on a mic and in case of bad cabling, the mic will pick it up. Also the main powerline ( the 32 and higher amp lines that is ) can give problems. There is one point in my house i can't use a mic because of the 64amp powerline in the floor going to other buildings. Even though my setup is balanced audio, de dynamic mic is picking it up.

My office has a fluorescent light -- humming was vile while using the cable that shipped with my Presonus AudioBox USB. Shielded cable fixed the issue. Love how they charge $200 for a USB audio interface and then ship it with a $.10 cable that negates its quality.

Without known the schematics or specifics I can only guess that the hum got into your analog audio stream via the amplifier IC's power supply. The cable picked it up and passed it on, so to say. To be honest, its pretty trivial to mitigate in the design and the fact that it wasn't speaks volumes about the quality of the device.

I've been wrong before though. Once. In '97.

Yeah the humm is definitely not Voicemeter but one of your hardware pieces. Some USB audio interfaces can be bad with this. Check your cables too, to make sure they are not at fault as well.
