4AM Cover

December 3, 2012 10:26 AM

Need a little help. Here's a nice little cover I did with a good old friend I've been playing with since highschool. Need some help. Using a logitech usb mic which I generally like the sound/versatillity/ portability of. Trying to figure out how to cut out the high-pitched noise it comes with.

Obviously, it'd be best to find a way to minimize it going in, but I'm open to post-prod solutions. I haven't found a good way to noise-cancel it out without really dumbing down the sound. Any ideas? I know it's a chintzy equipment problem, but I'm looking for the best-case-scenario on the thing. Thanks

Both Waves X-Noise and iZotope RX do a good job of noise removal but they are more expensive than just buying a decent USB mic, and if you get too aggressive there will be artefacts, especially in something spare like that guitar part, which has a lot of higher order harmonics. However I can have a go at it if you like.

(Often the optimal route is to reduce the noise rather than remove it...)

I've noticed some USB devices create noise when my laptop is plugged in, but not when it's running off the battery. If you're not using a laptop, a UPS or other power conditioner might help.

Otherwise: check out Spectro from stillwell audio - evaluation copy is free, and the plugins are reasonably priced and sound fantastic. I use their stuff in Reaper and think it's phenomenal.

Here you go. I used iZotope RX on its advanced setting and just reduced the broadband noise. I think there's a little bit of crispness gone from the top end but you could EQ it back in.

whoa. Thanks unSane! You didn't have to go the trouble. I'm definitely going to try out iZotope. Cheers!

Thanks to dubold as well.

Yeah, that high-pitched whine is almost certainly like ground loop interference, which as dubold says is common with laptops (not sure if it is a laptop you're recording with).

A ground loop isolator is the best and safest way of stopping that, you can get them at most hardware stores. You could also stop it by using a laptop charger that has a two-pin entry into the adaptor from the mains rather than a 3-pin, although I wouldn't recommend it as that would leave your equipment unearthed.

I like the recording by the way, I too like the sound of this mic.

I didn't know they existed, but USB ground isolators are pretty steep as it turns out.

I'm not convinced that is USB noise. In RX there was almost tonal component which is what you'd expect from a ground issue. I think it's just self noise from the mic. Condensers do sometimes get noisy -- I have a supposedly matched pair of condensers, one of which is really hissy sadly.

I would just try a different mic -- order it from somewhere where you can send it back if doesn't help.
