Free local track check + private mastering

Check the signal. Shape the sound.

Inspect a WAV or MP3 locally in your browser, then shape a focused master with a tape-inspired signal chain. The technical report informs your ears; it never claims to prove authorship.

Free browser tool

Check your track before you master.

Find level, clipping, DC offset, dynamics, stereo, and broad tonal-balance flags in one private technical pass.

Runs locally in this browser

Up to 100 MB and 10 minutes; the safe local limit can be lower on memory-constrained devices. Your audio is decoded and analyzed here—it is never uploaded by this tool.

The signal path

From upload to master in three focused moves.

01

Upload privately

Send a WAV or MP3 through your signed-in studio. Audio goes directly to private processing storage when available.

02

Choose your character

Use the fixed Classic chain, or set roll-off, tone, motion, saturation, width, hiss, and trim yourself.

03

Listen and download

A/B against your source and save the WAV. Private download access expires after ten minutes and deletion is requested.

Good to know

Clear answers before you upload.

What does “analog-inspired” mean?

The service uses digital signal processing to recreate selected tape-era traits such as high-frequency roll-off, saturation, subtle pitch motion, phase drift, and noise floor. No physical tape machine is claimed.

Is the result guaranteed ready for a vinyl pressing plant?

No automated master can guarantee plant approval. Confirm the plant’s exact level, duration, sequencing, mono-bass, and delivery specifications before manufacturing.

What files can I master?

Upload one WAV or MP3 track up to 10 minutes. Direct uploads support up to 100 MB; the studio shows the lower current limit if the server requires one.

What happens to my audio?

WordPress does not build a permanent audio library. The processing service makes the result downloadable for ten minutes. Access then expires and deletion is requested; storage cleanup is asynchronous.

Will this change an AI detector score?

There is no guarantee. Mastering changes sound, not a work’s origin or authorship, and third-party detectors can be unreliable.

Optional independent third-party check

Check the track with Detect.Music.

After mastering, download the WAV and select it again in the tool below. The file is not transferred automatically. AI detectors can produce false positives and false negatives; an estimate is not proof of origin or authorship.

YOUR CHOICE

Load the independent detector when you are ready.

The frame stays disconnected until you choose Load Detect.Music. That click connects this browser to MatchTune Inc.; files selected inside the frame follow Detect.Music’s privacy policy.

Third-party service operated by MatchTune Inc. Choosing Load Detect.Music connects your browser to that provider. Its privacy policy says original audio is discarded after feature extraction, while derived acoustic features may be retained indefinitely and server logs for up to 90 days. A detector score is an estimate, not proof of origin or authorship.
