Import MP3, WAV, M4A, or FLAC. Place colour-coded markers while listening. Edit notes, tags, and precise timestamps. Drag to adjust. Full undo/redo.
Load two tracks, switch instantly with 50 ms equal-power crossfade. LUFS-based level matching (EBU R128) — compare sound, not volume. Blind random test mode.
Record with real-time level meter and live marker placement. Lossless WAV (16-bit, 44.1 kHz) or compact AAC/M4A. Auto-imported when done.
Select input and output audio devices — built-in mic, USB audio interfaces, Bluetooth, wired headsets. Auto-fallback when a device is disconnected. Specs shown per device.
Built-in gentle compressor with adaptive threshold, 2:1 ratio, soft knee, and brick-wall limiter at −1 dBFS. Continuous auto-gain (AGC) keeps output peaks consistent. Adjustable input gain (−12 to +12 dB).
Loop between any two markers for focused listening — perfect for practicing instruments, studying sections, or reviewing specific passages. Sample-accurate timing.
Select 3+ files for sequential playback with track counter, shuffle, and loop. Save and load playlists (pro) for quick access.
K-weighted LUFS (EBU R128 / ITU-R BS.1770), short-term LUFS (3 s windows), peak dBFS, sample rate, channels, bit depth — all computed locally.
ZIP export with markers + audio. Direct SMB network export to Windows, macOS, Linux. Import audio files, ZIP exports, or from network shares.
Organise files into workspaces. Move files between projects. Cross-project search by name, ID3 metadata, marker notes, and tags.
Auto-reads artist, title, album, composer, publisher, comment from MP3s (ID3v1/v2, Vorbis, MP4 atoms). Shown everywhere — library, player, lockscreen, search.
Full landscape support across all screens — player, library, recorder, and project overview. Two-column layout in landscape for efficient use of screen space.
Whether you're reviewing mixes, practicing, or studying — AudioMark fits your workflow.
AudioMark works 100% offline with minimal data collection. No accounts, no ads, no in-app analytics, no tracking in the app itself. All your data stays on your device.

AudioMark is designed, built, and maintained by a single indie developer. It's a complex app — dual audio engine with real-time sync, DSP signal processing, EBU R128 loudness analysis, custom metadata readers, SMB networking, and three player modes in one screen. Every release is verified with a built-in test suite of ~200 test cases running on a real device. If you find a bug, please report it — I read every message and fix issues as fast as I can.
Found a bug, have a feature request, or just want to say hi? I'd love to hear from you.
