CD & Download
Full volume for CDs and direct downloads, with nothing turning it back down.

Voice & Podcast
Every word clear, even on phone speakers.
Best for: Spoken word, podcasts, audiobooks, voice-overs.
Loudness references
What the platforms aim for.
Streaming services normalise playback to their own level, so pushing a master harder does not make it louder there. These are the references the Podcast and voice workflow can target; check each platform for its current guidance.
| Platform | Integrated loudness | True peak |
|---|---|---|
| Spotify | −14 LUFS | −1 dBTP |
| Apple Podcasts | −16 LKFS ±1 dB | ≤ −1 dBFS |
| YouTube | −14 LUFS | −1 dBTP |
Questions
Straight answers.
Is my audio uploaded?
No. Mastering runs on your own device, in your browser. Your audio stays with you; the account only tracks your monthly download credits.
Is this a person mastering my track?
No. This is a tool you drive, not a mastering studio with a person in it. It listens, makes four finished versions and helps you choose.
What does it cost?
It is free to start: you can master and preview as much as you like, and downloads use a monthly credit allowance. Paid plans add more downloads and longer tracks.
Which files can I import and save?
Import WAV, MP3, M4A, AIFF or FLAC. Save as MP3, M4A, 16-bit WAV, 24-bit WAV or FLAC.
Will it fix a bad recording?
Mastering cannot fix a recording problem. If something sounds off in your original, it will usually still be there.
