Kiln Print / mastering studio
Turn a mix into a finished print.

Load one audio file, shape the master, and export a delivery WAV with the bit depth and normalization you choose. Render and preview are free; exporting a master is $1.99 per song, or unlimited with a subscription. The whole signal path stays local.

Stage 1

Upload one source track

Choose a mix or stem to stage locally. Nothing starts decoding until you press Start upload.

Choose one stereo mix or track. Validation, analysis, mastering, preview, and export all stay inside this browser. Processing happens in your browser, so your source audio stays closer to you—the artist.

Three moves, then listen

Each change makes a fresh browser-local preview. Your source track stays untouched.

Lower stays gentle; higher pushes the compressor and color harder.

      Difference, codec & adaptive

      Three browser-local additions. Codec sim is a preview-only lossy round-trip — the exported WAV is never codec-simulated. Adaptive processors add a slow trim that only moves when the envelope strays past a ±1.5 dB dead band. Difference spectra is a display-only before/after readout.

      Preview-only lossy codec round-trip for A/B checks.

      Bypassed

      Slow leaky-envelope trim with a ±1.5 dB dead band.

      Display-only before/after spectral difference.
