Live effects for everything your Mac plays – reverb, echo, pitch and more...
Music, videos, games, calls in the browser – everything your Mac plays runs through a small mixer with live effects. Turn up the reverb of a concert hall, add an echo from the mountains, raise or lower the pitch, or run a filter, a chorus, a flanger or a phaser over it.
Each effect has its own channel with two knobs and a fader that mixes it into the sound. A master control sets how much of all the effects ends up in the overall sound. Above the mixer, a live waveform and level meters show what you are hearing right now.
Pick one of the ready-made settings, or build your own and save it under a name. One click switches the effects off, and the sound goes to your speakers unchanged again.
• Eight effects: pitch, filter, drive, chorus, flanger, phaser, echo, reverb
• Each effect with its own knobs and its own mix control
• Master control for the share of the effects in the overall sound
• Live waveform and level meters
• Ready-made settings and your own, saved under a name
• “All off” with one click – and back again with the next
• Limiter that protects ears and speakers, can be switched off
• Mute when the phone rings
• Choose which speakers or headphones to use
• Small window that stays on top; light and dark design
• Set up once – macOS asks for your permission
