Media

Review sharpness, exposure and near-duplicates. Keep your best photos, not just the highest score.

Media

A full piano, a little room to play. Learn a phrase, connect a MIDI keyboard, or record your own.

Security

Review public BTC / Ethereum incident evidence, source coverage and token blacklist signals without connecting a wallet.

Text Processing

Find English and Chinese stock phrases, repeated openings, recurring phrases and monotonous sentence lengths, with evidence and editing prompts—not an authorship verdict.

Media

Estimate per-channel signal-to-noise ratio from separate program and noise-only regions, with an offline ZIP report.

Media

Scan the inaudible band of your recordings for hidden high-frequency tones: tracking beacons, flyback whine, aliasing images - with frequencies, durations and classifications.

Media

Measure wow and flutter of tape and vinyl transfers: weighted RMS per AES6/IEC 60386/DIN 45507, 2-sigma peak, and drift / wow / flutter / scrape band breakdown.

Media

Capture a noise fingerprint from a selected region of your audio - floor level, third-octave spectrum, hum harmonics, classification - then reuse it to denoise this file or any other file.

Media

Generate a shareable before/after report card for any loudness change: gain applied, LUFS, true peak, sample peak, loudness range, waveforms and third-octave spectral deltas.

Media

Measure your master once, then see the playback gain every major platform will apply — Spotify, Apple Music, YouTube, Tidal, Amazon, Deezer and more.

Media

Limit a master to a chosen true-peak ceiling (-1, -2, -1.5 or -0.3 dBTP) with a measure-limit-verify loop: FFmpeg’s lookahead limiter is driven below the ceiling by an inter-sample margin, and the result is re-measured with the BS.1770 oversampled meter until the true peak genuinely sits under target.
