A real mastering studio in your browser — tune loudness, EQ, stereo width and limiting with live controls, A/B the result against your mix, and download a store-ready master. Mastering usually costs $20–50 a track. Here it's free, instant, and 100% private — your audio never leaves your device.
Adjust the controls, hit “Apply / Re-master”, A/B it, then download. This is an instant auto-master — loud, clean and store-ready in seconds.
Streaming platforms normalise to about −14 LUFS. Set your target and this studio lifts your mix to it with a transparent limiter, shapes the tone with EQ, and widens the stereo image — then lets you A/B against the original so you can hear exactly what changed.
