Bring clarity and space to your mix, and loudness to your track

Whether you’re mastering a Top 40’s hit, a country ballad, a booming trap beat or anything in between, VIRTU can give you a polished, pro result. Use the Style preset that matches your Genre or mix and match.

Professional Masters In Minutes

Upload Your Mix

First, import the final bounce of a stereo WAV file mix. VIRTU will then quickly analyze your track to optimize the mastering process.

Select Style & Loudness

Select the ‘Style’ that best suits your track and choose one of the three loudness targets. You can also access a set of advanced controls to adjust the frequency balance, compression and stereo width of your master.

Preview & Print

Once you’ve selected your desired settings, you can preview 15 seconds of mastered audio before you commit. If you like what you hear, click ‘Master’ to process your entire track, then download it from the library!

Expertly-Crafted, Curated Curves

Give your track the final touch it deserves. Virtu lets you take the wheel of your own mastering process with the Advanced Controls and dial it in to taste. The EQ curves and compression algorithms have been calibrated by Slate Digital’s team of experts by hand (and ear), and take inspiration from some of our most beloved emulations, like FG-Dynamics, FG-2A, and FG-Stress.

Intelligent analysis delivers Peak perfection

VIRTU’s intelligent mastering process is sensitive to each track. During the analysis phase, it measures key signal properties (i.e. Peak, RMS, and Average) on different frequency bands to retrieve information about the tonal balance, loudness, and dynamic range of the track. That information helps determine the set EQ curves, multiband compression ratio & threshold, limiter gain, and other key parameters that will define your final master.

Take Advanced Control

Frequency Balance

The frequency balance section lets you make final adjustments to the overall EQ profile of your track. You can either boost or cut both the highs and lows of your master, or leave the end result unaffected to retain the sonic character of your original mix.

Compression setting

The compression setting lets you adjust overall compression level of the track. If you want a more neutral result, leave the compression balanced. If you want some extra punch or you’re looking for a more in-your-face master, the ‘Punch’ or ‘Aggressive’ settings are your best bet.

Stereo image

Add some extra width to your master with the stereo widening tool. You can choose to either leave the end result relatively unaffected with the default ‘Balanced’ setting, or you can introduce even more dimension with the ‘Wider’ setting.
