Master music online with Standard Crown or Adaptive Crown processing. Mack Crown analyzes tonal balance, dynamics, low-end control, stereo image, vocal clarity, loudness, and true peak before preparing the finished file.

Upload a full mix, choose the delivery goal and sound character, compare the source with the master, review technical validation, and download a polished WAV for streaming, video, or release distribution.

Mastering questions

Can I preview before paying?

Yes. Upload a source mix on the homepage to hear a playable 30-second Crown preview before choosing a final master.

What does one final master include?

One approved master includes both a 24-bit WAV and a 320 kbps MP3. Downloading both files does not use an additional Master Credit.

What file types does mastering support?

Upload WAV, AIFF, FLAC, MP3, M4A, AAC, or OGG. Crown delivers your final release master as WAV and MP3.

How do Crown Studio downloads work?

Crown Studio includes 20 master downloads per billing cycle. A download is consumed only when an authenticated final file is released; previews, failed renders, and re-downloading the same master do not consume another download.
