MR Noise – Stellar Sounding Broadband Noise Reduction

“MR Noise” is a broadband noise reduction processor. It distinguishes itself by being both great sounding and incredibly easy to use. Like most noise reduction systems, MR noise works in the frequency domain, and requires that the noise spectrum be learned before noise reduction can commence.

If your track starts with a bit of silence then MR Noise will work right out of the box, since by default MR Noise has the Learn parameter enabled, then when you hit play, MR Noise will learn the noise profile and start noise reduction. The default parameters work extremely well for most cases.

When designing MR Noise, Wave Arts spent considerable effort researching and experimenting with existing noise reduction algorithms.

MR Noise combines the best of these with some new innovations, especially the Auto Dynamics mode.

This mode automatically adjusts the attack and release times of the noise reduction processor based upon the amount of transients in the input signal. This minimizes artifacts in the noise reduction processing while maintaining sharp transients that would normally be smeared by other methods.

The user interface makes it a snap to see and hear what is going on. The frequency response display shows the spectrum of the input signal, noise floor, and output signal so you can see at a glance what frequencies are being reduced.

A monitor feature allows you to hear the noise that is being removed (with separate volume control). For most cases you simply have to select a preset and hit play, MR Noise will learn the floor and start reduction. Then you can simply adjust the Amount control to set the amount of reduction.

For super fine tweaking, the noise floor and all the reduction parameters can be edited as a function of frequency by dragging control points on the frequency response display.

MR Hum – Precise Hum & Buzz Removal

Combining hum removal, buzz removal, brickwall filtering, and spectrum analysis into one easy to use plug-in, “MR Hum” is the perfect tool to clean up recordings with any sort of hum or nasty buzz.

The hum removal section works by applying a set of notch filters spaced at multiples of the fundamental hum frequency, usually 60 Hz or 50 Hz. You select the fundamental frequency, the number of harmonics you want to eliminate (up to 10), and the width of the notches (the default works fine).

There are presets for the usual cases of 60 Hz hum and 50 Hz hum. You can also select any fundamental frequency continuously from 20 to 200 Hz. Sometimes it’s necessary to use a slightly different frequency in cases where the hum has been recorded on analog tape and played back on a different machine, which will cause the hum frequency to change.

The high resolution spectrum display makes it easy to see the hum frequency and the number of harmonics that are required. The spectrum display can run before processing, to see the input signal spectrum, or after processing, to see the output signal spectrum. The monitor feature allows you to hear the signal being removed, offering another way to set the parameters.

MR Hum contains a separate processor for buzz. Buzz is a periodic signal with frequency harmonics through the entire audible spectrum, which would require hundreds of notch filters to eliminate. The buzz algorithm uses a different approach which is far more efficient.

Often buzz is a nasty case of hum, and hence is at 50 or 60 Hz, but sometime buzz is caused by a motor or some other kind of interference, hence the buzz processor allows any frequency from 20 to 200 Hz.

Finally MR Hum also provides brickwall filters to eliminate low or high frequency interference.

Master Restoration – The Ultimate all-in-one Cleanup Tool

“Master Restoration” combines the functions of MR Hum, MR Click, MR Noise, and MR Gate into one plug-in. The signal processing order is MR Hum, MR Click, MR Noise, and MR Gate.

When any of the processors are monitored, the output consists of a mix of all the monitor outputs from the processors. Hence, you can monitor any combination of the processors to hear a mix of all the signals that have been removed by the individual processors.

Monitoring sections

Each section has a MONITOR button which can be selected to hear the signal that is removed by the processor. In Master Restoration, it is possible to select multiple sections to be monitored, in which case the output contains a mix of the monitored sections.

Master Restoration has separate gains for monitored and non-monitored output. Hence, when monitoring, you can increase the output gain control to more easily hear the monitor signal. When monitoring is turned off, the normal output gain is applied.

Section presets

In Master Restoration, each section has a preset control as shown below. Click on the button to advance to the next section preset (SHIFT-click moves backwards to the preceding preset).

Click on the text area to display a popup menu of preset options. There are rolloff menus for factory and user presets, and Save and Save As options for saving a section preset.

Sharing presets between processors

User presets created in the various processor sections of Master Restoration are automatically imported into the individual plug-ins. Simply save the preset using the section preset control, then you will see this preset in the main preset menu of the individual plug-in.

For example, if you save a preset in the Noise section of Master Restoration, this preset will be available in the MR Noise main preset menu, under the User rolloff menu. Similarly, if you save a preset in MR Noise, this preset will automatically appear in the preset control of the Noise section of Master Restoration.
