Transform your audio with simple EQ
Apply studio‑grade EQ to your videos and audio files, preserve original video quality, and export in formats that play everywhere — all on your Mac.
Open a file, adjust the 8‑band equalizer (or pick a preset), and export. EQ Studio keeps your original video untouched while replacing only the audio track with your EQ’d sound.
