How Online Audio Mastering Improves Your Song
Online audio mastering gives a finished mix a clear, balanced, release-ready sound. The automatic mastering process adjusts EQ, compression, stereo width, loudness, and true peak. Choose a preset, compare your mix with the master, and download a WAV. Online AI mastering is free to start with no signup.
Shape a balanced sound
Corrective EQ reduces muddy areas and brings out useful detail. This gives the mix a clearer balance from bass to treble.
Add clean stereo space
Stereo processing adds width to the upper range while keeping low sounds focused. The master feels wider without losing a solid center.
Control loud and quiet parts
Compression controls sudden jumps and supports quieter details. This helps the song feel steady, clear, and full.
Set the final loudness
LUFS sets the overall level, and the true peak ceiling controls the highest short peaks. The result panel shows both measurements.
Choose a Mastering Target for Your Release
Choose a sound preset to shape your song. You can also choose a platform preset for your release. The normal Spotify mastering preset uses a −14 LUFS target and a −1 dBTP ceiling. Other presets cover Apple Music, YouTube, SoundCloud, TIDAL, Amazon Music, Deezer, universal streaming, and club playback.
Use the Sound tab for Balanced, Warm, Bright, Loud, or Bass Boost. Use the Platform tab when you want a named loudness target for a release.
