I'm just waiting for BGB to add adjustable hum emulation

If you dont like the charm of hum, then you could use a Gameboy PC emulator + LSDJ and record straight from the computer into the computer?

Oops. I meant audio system, not wav writer.

You can select other writers?

Quality of prosound mod should also be noted.

I've had to repair a number of less than professional soldering, materials, and mod work over the years.

Do you have power save enabled?

Btw I can't hear any hum in the music I make, there is while manipulating lsdj menus and such, but when it's playing it's pretty silent.

I haven't tried the so-called "prosound", and I'll probably test it on one of my DMG to check if it can be better (louder bass?), but here is what I get from my DMG:

At 1'22" there is a kind of break with only some drum, you can hear some background noise, but no hum.

post a clip, to see what type of noise we are talking about. Whats your recording device?

It's possible that your DMG isn't in the best condition. It might need new capacitors. Old caps can cause all sorts of noise.

I just use the noise reduction effect in audacity to take out those last bits. Works pretty well for me.

Your best option is to get BGB working properly.  Look in the settings tab for latency or buffer settings (don't have it in front of me at the moment).  Also check what wav writer is selected and experiment with other options.  BGB can sound stuttery when rendering but the wavs should still come out perfect as long as your system is configured appropriately.

BGB FTW!!!

The best way is to realise that you are making music with a Game Boy and just roll with it

why are you recording each channel individually? I mean, probably for altering them afterwards, but in this case, why are you using a gameboy and not some VST instead? I think the raw, unmodified sound from the gameboy is part of the pleasure for using it.

do you get the same hum if you record off of something like an ipod?
