Listening to music has never looked this good.
No extra software to spot a drop or try an EQ. Waveform, spectrum, and EQ sit together, and switching tabs never stops the music. All of it free.
A typical player has play and volume. Checking a track on a different sound system, studying a drop, or finding a mix point means opening another app.
Color waveform
Colored by lows, mids, and highs, so drops and breakdowns stand out.
Real-time spectrum
95 bands from deep bass to top highs, moving with every beat and flaring at the peaks.
Parametric EQ
Drag points right on the spectrum to boost or cut any band, or use a familiar 10-band EQ.
43 presets
Pick by mood, genre, or where you listen. Save your own.
Stereo space
Stereo widening, bass mono for big systems, and crossfeed to ease ear fatigue on headphones.
Tempo with key lock
0.5× to 2×, or match your set's BPM, like Master Tempo. Starts after the intro and moves on before the outro (you set the seconds).

FAQ
Will big EQ boosts distort?
No. The app lowers the level when needed so the sound does not break up. You can also pull Preamp down.
How do I compare before and after?
Uncheck Apply to hear the original, check it again to hear your changes.
Does switching tracks reset my EQ?
No. Your EQ stays as it is from track to track, and even after you restart the app.
