ToneEQ: Headphone Equalizer

About

Every headphone sounds different. ToneEQ helps every pair sound like yours. ToneEQ is a headphone equalizer and local music player that remembers how you like to listen. Create a sound profile for each headphone, speaker, or DAC, then automatically restore the right EQ when your audio device changes. CALIBRATE YOUR HEADPHONES Choose a supported headphone model and start with its AutoEq correction profile, or begin with a flat response and tune the sound yourself. ToneEQ keeps headphone correction separate from your personal preferences, so you can improve accuracy without losing the bass, warmth, vocal presence, or brightness you enjoy. SHAPE YOUR SOUND FOR FREE The essential sound controls are available without a subscription: • 10-band graphic equalizer • Real-time frequency response curve • Instant EQ bypass for A/B comparison • Automatic preamp compensation • Output headroom estimation • Built-in clipping protection • One automatically restored device profile PLAY YOUR OWN MUSIC Import audio from Files, iCloud Drive, and compatible file providers. Your local music is played through the ToneEQ audio engine, giving you full access to its equalizer and sound profiles—even without an internet connection. Supported formats include: • FLAC • ALAC • MP3 • AAC and M4A • WAV • AIFF Browse your library by song, album, artist, or folder. Build a queue, search your collection, control playback from the Lock Screen, and keep listening in the background. THE RIGHT EQ FOR EVERY DEVICE ToneEQ detects changes to your current audio route and clearly shows which device and sound profile are active. When you reconnect a saved headphone or DAC, ToneEQ can restore its assigned EQ automatically. No screenshots, repeated adjustments, or forgotten presets. GO FURTHER WITH TONEEQ PRO ToneEQ Pro adds advanced control, personalization, and profile management: • Parametric EQ with up to 10 filters • Precise frequency, gain, and Q controls • Multiple named EQ profiles • Profiles for multiple audio devices • Automatic profile selection • Personal Listening Match • Separate correction, preference, and scene layers • Profile import and export • Private iCloud profile sync FIND YOUR SOUND BY LISTENING You do not need to understand frequencies or read an EQ graph. Listening Match presents a series of carefully controlled A/B comparisons. Simply choose which version sounds better. ToneEQ gradually learns your preferences for bass, warmth, vocals, and brightness, then creates a personal EQ profile you can preview and edit. CLEAR ABOUT WHAT IS BEING PROCESSED ToneEQ applies software EQ to supported audio played through its own audio engine. Apple Music content can be browsed and controlled through Apple’s platform player. Because protected Apple Music audio remains in Apple’s playback path, ToneEQ clearly shows when software EQ is unavailable. ToneEQ does not claim to provide system-wide EQ for audio from other apps. PRIVATE BY DESIGN Your audio files stay yours. Sound processing and Listening Match calculations happen on your device by default. ToneEQ does not upload your music, sell your personal information, or show third-party advertising. Optional profile synchronization uses your private iCloud database and never uploads audio files. Switch headphones. Keep your sound. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
