About this launch
MasteringKit is an online mastering service for musicians releasing their own songs. Users upload a finished stereo mix and receive a free 30-second mastered preview in about a minute without signup. The service applies EQ, compression, saturation, stereo processing and limiting to finished mixes.
Users can adjust their master through eleven controls, an intensity setting, a six-band EQ, or by writing plain-language descriptions like "warmer, less harsh highs" to get new versions. Six mastering engineer styles—Avery, Rio, June, Theo, Nova and Sol—provide different starting points for the same track.
Every change creates a new version that can be compared while the track plays. Full-track downloads in WAV 24-bit or MP3 320 kbps require a paid plan. Free accounts include 10 additional revisions per project beyond the initial preview.

Shopper questions
What is mastering?
Mastering is the final step before release that balances tone, controls dynamics, sets stereo image and brings a track to competitive loudness for different playback systems. MasteringKit applies EQ, compression, saturation, stereo processing and limiting to finished mixes.
Which files can I upload?
WAV, MP3, FLAC, AIFF, M4A or OGG files up to 1.5 GB and 22:30 long. Upload the final stereo mix with headroom and no limiter on the master bus if possible. Paid plans export WAV 24-bit and MP3 320 kbps.
How long does mastering take?
The first 30-second preview is usually ready in about a minute. Each adjustment after that takes a few seconds. When you finalize, the full-length master is ready to download a minute or two later.
Can I release my master on Spotify and Apple Music?
Yes. Download the WAV and send it to your distributor as usual. Streaming services normalize loud tracks to a common level, so the Balanced loudness setting is recommended for streaming, with louder settings available for club and DJ use.
How long does it take?
Your first 30-second preview is usually ready in about a minute. Each change after that takes a few seconds. When you finalize, the full-length master is ready to download a minute or two later.
