FAQ

Quick answers, no fluff.

Does my audio get uploaded anywhere?

No. The whole thing runs in your browser. Your file never leaves your device — not the audio, not the metadata, not anything.

What does it cost?

• Free: 3 masters total, MP3 download.
• Pro: $4.99/month — unlimited masters, WAV export. Cancel anytime.
• Lifetime: $29 one-time, first 100 customers only.

What's the difference between STREET / MODERN / OPEN?

• STREET — louder, brighter, more punch. Hip-hop, EDM, pop.
• MODERN — balanced. Works on most material. Default.
• OPEN — gentler, more headroom. Acoustic, jazz, anything you don't want squashed.

What does FINE-TUNE do?

Real-time tweaks on top of the master:

• LOUDNESS — overall gain ±6 dB
• BASS — low-end ±6 dB
• AIR — high-end ±6 dB
• WIDTH — stereo width: mono → super-wide

The labels turn yellow when you push it, red when you break it. They guide you.

Will the master make my track louder?

Depends on the input. Already-mastered tracks get a polish. Raw mixes get +3 dB and audible glue. We try to be honest — if your file is already at the ceiling, we won't pretend to add 6 dB more.

Does the WAV download include my FINE-TUNE settings?

Yes. Whatever you heard while previewing AFTER, that's what gets baked into the WAV.

Will it work on mobile?

Yes — designed mobile-first. Tested on iOS 16+ and Android Chrome.

How do I cancel Pro?

One click in your account → Manage Subscription. You keep Pro features until the end of your billing cycle.

Is it really "mastering"?

It's the same chain pro engineers use: EQ → bus compressor → make-up gain → true-peak limiter at -1 dBTP. Tuned per-track based on what you upload. Will it match a $1000-an-hour engineer? No. Will it sound a hell of a lot better than your unmastered demo? Almost certainly yes.

I think I found a bug.
