How to use this workflow

  1. Load your mix

    Choose a supported audio file and keep an untouched original. Listen for the specific issue you want to address, such as excessive bass or uneven peaks.

  2. Choose a starting preset

    Balanced, Warm, Bright, Punchy and Bass Heavy provide starting settings. Adjust low, mid and high EQ, compression, saturation and output gain to suit the recording.

  3. Compare and export

    Generate the result and compare source and processed sound using the A/B preview. The Original comparison applies RMS level matching automatically. Download WAV or MP3 after checking both quiet and loud passages.

What each stage contributes

EQ changes the balance of frequency regions. Compression reduces dynamic differences according to the processing settings. Saturation adds nonlinear coloration and can sound harsh when pushed. Output gain changes the final level.

Choose one objective at a time. If a vocal is masked by bass, compare a small low-frequency reduction before increasing all other bands. A preset is an editable starting point, not a diagnosis of the mix.

Understand the level measurements

The comparison uses an RMS-based level match, measured over at most the first thirty seconds. That can make A/B decisions easier, but it is not an integrated LUFS measurement of a complete program.

The processing has a fixed sample ceiling of approximately −0.1 dBFS. A sample ceiling is not a true-peak limiter, and MP3 encoding can change reconstructed peaks. This page does not certify a streaming platform’s loudness or delivery requirements.

Common questions

Is this automatic AI mastering?

No. The tool applies the displayed EQ, dynamics, saturation and gain settings. It does not analyze a mix and promise an engineer’s mastering decisions.

Can mastering restore a clipped recording?

It cannot recover the original waveform removed by clipping. Lowering gain may reduce the level, but existing distortion can remain.
