User Guide

1. Create or access your account

Use the Sign up page to create a new account, or the Sign in page if you already have one.

Once authenticated, you can access the Studio, your Account page, pricing information, and your current mastering workspace.

2. Upload a track

From the Studio, drag and drop one or more audio files into the upload area or click to choose files from your computer.

Each uploaded track is analyzed before the full waveform and mastering controls become available. Larger files and longer songs naturally require more time during this phase, especially when preparing a detailed online mastering preview.

• A clean stereo mix without clipping usually gives the best result.
• WAV or other high-quality source formats are strongly recommended for professional audio mastering.
• Keeping some headroom generally helps the mastering engine behave more transparently.

3. Review the selected track

When a track is selected, the player displays the waveform, transport controls, current timing, before/after switch, and the status currently associated with that file.

The track list lets you move between files, identify mastered tracks, reopen existing work, and keep track of what is still waiting, processing, or completed.

4. Use Before / After listening

The before/after switch lets you compare the original upload with the processed output or available preview.

This comparison is essential if you want to judge loudness, tonal balance, stereo width, dynamics, and the general character of the master rather than relying only on louder playback. It is one of the fastest ways to evaluate an online mastering service in real listening conditions.

5. Adjust presets and parameters

The Presets & Parameters panel gives you a starting point through automatic or stylistic presets and then lets you refine the result manually.

Standard controls are intended for fast and practical adjustments, while Pro controls offer a deeper level of shaping when your plan includes them.

• Standard controls
• Low Cut reduces unnecessary low-end energy.
• Air Boost increases clarity and presence in the high frequencies.
• Compression affects glue, punch, and perceived density.
• Width adjusts the stereo image.
• Loudness controls output intensity and perceived level.
• Pro controls
• Target LUFS defines the integrated loudness target used for export level.
• True Peak Ceiling limits the maximum peak level more precisely to protect headroom and delivery safety.
• Limiter Release changes how quickly the limiter lets go after peaks, which affects density and punch.
• Limiter Lookahead gives the limiter more time to anticipate transients and react more cleanly.
• Mono Low Freq controls how much of the low end is kept mono for tighter and more stable bass.
• Phase Safe helps keep the stereo image more compatible and reduces phase-related issues.
• Dynamic EQ adjusts corrective tonal control in a more adaptive way than static EQ.

6. Start mastering

When your settings are ready, launch mastering from the active track.

The job is queued, rendered, and then written back to the track state. The status updates automatically when the output becomes available.

• Starter access may focus on preview-oriented behavior depending on the active offer.
• Paid plans unlock full exports and broader mastering options.
• If you remaster a track, the newly generated result can replace the previous one.

7. Download or rework the result

Once mastering is complete, use the download action to retrieve the processed file when your plan allows it.

If the result is close but not final, make a limited adjustment, compare again, and launch another pass rather than changing everything at once.

8. Manage your account and subscription

The Account page is where you manage profile information, access details, and account-level settings.

The Pricing page explains the difference between plans, including export access, control depth, album-oriented workflows, and the level of access you get inside the audio mastering platform.

9. Tips for the best result

• Upload the cleanest available version of your mix.
• Avoid heavily clipped premaster exports unless that character is intentional.
• Compare before and after at a matched listening level whenever possible.
• If the result feels too bright, too wide, too compressed, or too loud, start with a small correction.
• For releases with several tracks, keep a consistent settings strategy across the project.
• If you are mastering for streaming platforms, make decisions with translation, punch, and tonal balance in mind rather than loudness alone.
