Waves Ltd's X-Hum is an audio restoration plug-in that aims to remove hum gotten from not being properly grounded and otherwise. It works in a way where there are 8 harmonically linked notch filters that work simultaneously to remove the full hum. Ever wonder why it's hard to fully remove noise with a single band of EQ without losing something? I installed this plug-in along with the full Waves Complete bundle, so doing so wasn't any different than installing any of the other Waves plug-ins, as it shouldn't be anyway. The interface of the plug-in gives you control over the primarily frequency and Q width, as well as eight gain knobs for each of the filters. Everything is plotted on a graph for easy visualization. Other parameters include a high pass filter and overall output levelers. I haven't had a look at the manual for this plug-in as one wasn't really necessary for me.

SUITABILITY/PERFORMANCE

The system that I'm running the Waves Ltd. X-Hum plug-in on at home is Pro Tools LE based. I'm running version number 8 of the industry standard DAW with a Digi 002R audio interface. The computer I'm running everything on is a Mac Book Pro lap top that consists of a 2.2 Ghz Intel Core 2 Duo processor, and 4 GB of RAM. This has been more than adequate for running this plug-in, as I've never needed to run more than one or two instances at a time.

OVERALL OPINION

The Waves Ltd. X-Hum is only found in the Waves Audio Restoration bundle and other plug-in bundles as it isn't available as an individual plug-in. If you're looking into this plug-in, chances are that you're going to want the complete Audio Restoration bundle anyway. This is by far the way to remove hum and other noise that I've found out there. It's incredibly precise, and if you know what you're doing a little bit, more times than not it will do an awesome job. If you're looking for some tools to remove all types of unwanted noise, there's nothing better than this bundle and X-Hum!
