Flacseed

A mindful listening studio

Coming Soon

iPhone · iPad · Mac

You've bought the binaural audio. You've tried the meditation apps. But you've never been sure the beats are real—and you've never been able to layer your own voice over a lossless bed. Flacseed lets you build your own practice audio from music you already own. Verify the frequencies. Add your affirmations. Own your calm.

Create

Layer up to 12 tracks over a main bed. Add binaural beats you design. Record voice guidance. Build sessions that are truly yours.

Verify

The analyzer measures the actual beat frequency in your audio—not marketing claims. See "Verified 6 Hz Theta" before you press play.

Own

One price, forever. No subscriptions. No data harvesting. Your files never leave your device. Your practice belongs to you.

Bit-Perfect Playback

FLAC, ALAC, and high-res audio played exactly as recorded. No resampling, no hidden processing.

Studio Mixer

Layer tracks with per-layer volume, panning, fades, and loop points. Audition in real-time.

Beat Designer

Generate binaural, monaural, or pulsed beats. Choose carrier and target frequencies. Add drift and richness.

Noise Designer

White, pink, brown, blue, violet. Shape ambient beds with volume curves and pulse rhythms.

Voice Recording

Record affirmations and guidance directly in the app. Layer them into your mixes.

Timed Sessions

Focus blocks and sleep sessions with settle-in, work, and reflect phases. Track your practice streak.

Frequency Analysis

Detect and classify binaural beats: Delta, Theta, Alpha, Beta, Gamma. Filter your library by verified band.

Live Radio

Stream lossless Icecast stations. Add your own URLs. No bundled content—just what you choose.
