Megahertz™ - HiRes FLAC Player

Your compilations and soundtracks finally group into one album instead of splitting by artist. Plus a new grid view for every tab in your library. More polish and tweaks.

Megahertz is a powerful, audiophile-grade music player for your local library. No streaming. No subscriptions. No ads. Just your music, played exactly how you want it. Now on iPhone, iPad, and Apple Silicon Macs.

Built for discerning listeners: Connect a USB DAC and enjoy bit-perfect audio playback when the DAC's sample rate matches the file. Megahertz passes your music through untouched, so you hear exactly what the artist intended. Whether you are on reference headphones or a hi-fi setup, your signal stays clean from file to output.

Parametric EQ: Go beyond simple presets. Sculpt your sound with a full parametric equalizer: adjust frequency, gain, and Q for each band. Save custom profiles for different headphones, rooms, or moods. Import custom AutoEQ profiles from the community catalog via URL.

Your library, enhanced: Megahertz reads rich metadata and artwork directly from your files, then enriches your library with artwork from iTunes and MusicBrainz, synced lyrics via LRCLIB, and smart genre suggestions from iTunes. Browse by Songs, Albums, Artists, Genres, or Composers. Build smart playlists like Recently Added, Most Played, Top 100, Favorites, and Lossy-only. Manage playlists manually or export them to M3U.

Made for customization: Tweak the interface, organize your library your way, and make the app feel like yours. Megahertz is built with SwiftUI for a fast, fluid, native iOS and Mac experience. Full Reduced Motion support ensures the app is comfortable for everyone.

Privacy-first: No accounts. No tracking. No data collection. Your music stays on your device.

Megahertz is a one-time $9.99 purchase. No in-app purchases, no subscriptions, no data harvesting. Just a music player that respects you and your privacy.
