Online mastering

Online mastering that runs on your machine, not a queue

Most online mastering means uploading your mix, waiting for a server, and hearing a watermarked preview. MixTrackLab masters the file locally in your browser at full quality, so you can try every signature and every loudness target as many times as you want before you decide to export.

The workflow

  1. STEP 1

    Load your mix

    Drop a stereo WAV, AIFF, or MP3 — it stays on your device.

  2. STEP 2

    Pick a signature

    Clean, Warm, Modern Pop, Club, Streaming, or Radio.

  3. STEP 3

    Set the target

    Choose a loudness target and true-peak ceiling for your release.

  4. STEP 4

    Export

    24-bit WAV, quality-checked for harshness and over-limiting.

What the master actually does

The chain measures your mix first: integrated LUFS, short-term loudness, loudness range, true peak, crest factor, and spectral balance. Then it applies corrective EQ, multiband dynamics, tonal shaping, stereo imaging, and a true-peak limiter — sized to what the measurements say, not to a fixed preset.

After every pass, the result is re-measured. If limiting has flattened the crest factor or pushed the top end into harshness, the chain backs itself off and re-renders instead of handing you a fatiguing master.

Loudness targets for every platform

Streaming platforms normalize playback, so a louder master is not a better one. Pick a target around -14 LUFS integrated with a -1 dBTP ceiling for Spotify, Apple Music, and YouTube, or push denser targets for club and radio delivery. The meters show exactly where you landed.

Reference-matched, if you want it

Load a commercial record you want to sit next to and the master is compared against it on spectral balance, crest factor, and loudness — so you are chasing a specific sound rather than a generic curve.

No upload, no waiting, no watermark

Because processing happens in the browser, nothing is transmitted to a server and there is no per-render cost. The audio you audition is bit-for-bit the audio you export, at full length. You only pay when you download the file.
