How online mastering works
From your final mix to a release-ready 24-bit / 48 kHz WAV in four clear steps.
Upload your WAV
Drop a genuine PCM or IEEE-float WAV up to 150 MB. The server validates the complete file before processing.
Choose your sound
Start with Balanced, Warm, Open, Punch or Modern. Each model creates a real server-rendered preview.
Compare in sync
Switch between Original and Mastered without restarting playback. Both versions stay at the same timecode.
Pay and download
Listen to the 30-second preview, pay exactly €5 with PayPal, then download one 24-bit / 48 kHz WAV.
What mastering changes
The engine analyses level, dynamics, tonal balance, stereo information and peaks. It then applies a controlled processing chain selected for the chosen model. The −1 dB peak ceiling protects delivery headroom; it is not a promise that every mix will sound the same.
