Media
Convert local images to RGB555 or 16/256-color textures with ordered dithering and an affine, vertex-snapped 3D preview.
Classify a track into genres from measured evidence: GTZAN timbral-texture features, beat-grid pulse shape, band balance, key and dynamics — with a ranked top-3 and the reason behind every pick.
Turn one track into finished remix versions in a single pass: slowed + reverb, nightcore, 8D rotation, club edit, radio edit, plus Demucs-powered instrumental, acapella and drums-and-bass — all delivered in one ZIP.
Sharpen or soften drum attacks and lengthen or tighten drum tails without a threshold, using SPL-style differential envelope detection.
Analyze a drum track or full mix into a step-sequencer pattern: BPM, beat grid, kick/snare/hi-hat hits quantized per bar, drum MIDI, and an HTML grid report.
Detect kick, snare, and hi-hat hits in a drum track or full mix, then layer or replace them with your own samples (or built-in synthesized ones).
Convert subtitles between WebVTT, TTML (with SMPTE frame timing and styles), YouTube SBV and SRT — frame-precision time axes (23.976/24/25/29.97 drop-frame/30/50/59.94 DF/60), TTML tts styles bridged to WebVTT ::cue CSS, cue-id uniqueness, and IMSC 1.0.1 compatibility checks.
Enter a melodic contour as scale degrees (1-7 or do-re-mi) plus a target key, and get candidate diatonic chord progressions ranked by voice-leading smoothness, with roman-numeral analysis and an audio demo.
Inspect real sample depth, stored pixel depth, channels, palette, alpha, color space, ICC, and HDR metadata.
