If you’ve ever had to deal with a noisy track, you know how time consuming clean-up can be. Yes, you can gate it, but that can sound unnatural. There are also many excellent noise-reduction plugins available, but they don’t always do the job without adding some unpleasant artifacts. You find yourself playing with different combinations of tools hoping that you can eventually dial in something acceptable, which can take a lot longer than you’d expect. That’s why the new Audionamix Speech Volume Control (SVC) is so cool. It takes an entirely different approach to noise reduction.
Most noise control plugins try to eliminate or concentrate on the background noise, but SVC works by increasing the level of the vocal or speech so that the noise is no longer a problem. Keep in mind that this is a tool intended for post engineers who work with dialog, but the plugin looks like it can have many uses in music as well (I can’t wait to try it on noisy distorted electric guitars, for example).
SVC has to first acquire the audio in order to be able to work with it, and this done using the Aquire button, and then the Separate button to allow the algorithm to do its thing (the track can be mono or stereo, by the way). At that point, there are a variety of controls, but the main ones are the Speech volume slider and the Background volume slider, which will then allow the user to find the right combination of noise to track that seems natural. There’s also a Pitch slider, which works in conjunction with a number of presets for different types of voices, that allows you to fine-tune the algorithm to the voice.
There are also High Quality, HF Boost and Reverb options (the Reverb selector maintains the wet/dry balance as you adjust the Speech volume control), as well as an Automatic Voice Activity Detection that helps to precisely target the speech content within your audio file.
The Audionamix Speech Volume Control plugin costs $249 to buy and $19.95 for a 2 week rental. It’s available in AAX, VST and AU formats for both Mac and Windows platforms. Check out the video below, or the website for more info.
