MasterTrack on a computer, in PRIME: a colourful stereo waveform, the stereo field and LUFS meters above the gold panel with GLUE, HARMONICS, DRIVE, WIDTH and OUTPUT, and the CLEAN UP, SHINE, PRIME, HQ MODE, DELTA and MASTER buttons.

The controls

Every control on the panel, in plain words. The names are the ones printed on MasterTrack.

Shape the sound

DRIVE
Adds analog-style density, warmth and saturation while keeping the punch of the low end. It's the big knob in the middle.
GLUE
Adaptive mastering compression that pulls the mix together. Hover over it or drag it to see the gain reduction.
HARMONICS
Adds harmonic detail and presence while keeping the top end smooth.
WIDTH
Widens or narrows the stereo image and keeps the low end mono-compatible. A light center detent marks the natural width.
OUTPUT
Sets the final level and drives the finishing stage. A light center detent marks 0 dB.
CLEAN UP
Removes extreme low and high energy the master doesn't need. On by default.
SHINE
Broad tonal polish for a finished mastering curve. On by default.
HQ MODE
Runs the saturation and finishing stages at four times the sample rate for higher quality. It uses more CPU.

Pick a character

PRIME is the polished mastering sound. PRESSURE is denser and more aggressive, and the panel changes to a worn hardware look to match. A and B snapshots remember which one you used.

Listen honestly

MASTER ORIGINAL
The COMPARE button switches between MASTER, in gold, and ORIGINAL, in red: your untouched mix, lined up in time and matched in level, so you're comparing sound and not volume.
DELTA
Hold it to hear only the difference MasterTrack makes.
STEREO MONO
Press STEREO and it turns to MONO, so you can check mono compatibility without changing your width setting.
A B
Two snapshots of your settings, including PRIME or PRESSURE, to switch between.

Hit your loudness

AUTO
Slowly corrects OUTPUT toward the integrated loudness you choose: −16, −14, −12, −11, −10, −9, −8 or −6 LUFS. Moving OUTPUT yourself hands control back to you, and heavy limiting can stop AUTO from going louder.
Meters
Momentary, short-term and integrated LUFS. True peak for left and right, with peak hold. Limiter and GLUE gain reduction. A stereo field display with correlation, and a waveform with the left channel above the line and the right below.

Start from a preset

Twelve starting points to adjust by ear. Loudness depends on your mix, so finish with the LUFS and true-peak meters. Presets leave HQ MODE and AUTO as they are.

Questions

Does MasterTrack work in Pro Tools?

No. There's no AAX version, so it doesn't run in Pro Tools.

Can I use it on more than one computer?

Yes, on up to 3 computers at a time, Mac or Windows in any mix. To move to a new computer, remove an old one in your account.

Is the iPhone and iPad version included?

No. It's a separate purchase on the App Store.

Do I need to be online?

Only to activate. After that, MasterTrack works offline and checks in now and then when you're connected. A computer that never goes online can use offline activation instead.
