kushagrasinghx/BitChord v1.4

BitChord v1.4

on GitHub

Merges the v1.4 set from #5 — lossless audio sourcing, beat-matched Automix, animated artwork and Discord Rich Presence, on top of a rewritten playback engine.

Top features

Hi-Res Lossless audio — FLAC/ALAC, with YouTube Music as automatic fallback. Playback starts on the fastest stream and upgrades to the better one in the background. Separate quality ceilings for Wi-Fi and mobile data.

Automix [Beta] — DJ-style transitions in place of a plain crossfade. An on-device analyzer reads tempo, beat grid, key, song structure and vocal activity, then beat-matches, tempo-stretches and phrase-aligns the mix, with bass handoff and filter sweeps. Falls back to equal-power crossfade when a track can't be mixed cleanly.

Animated album canvas — Motion artwork on the now-playing screen, from Apple Music, Tidal and community canvases, with full-bleed mode and still-image fallback.

Discord Rich Presence — In-app login, live track/artist/album and progress, plus configurable status, activity type and up to two custom buttons.

Word-synced lyrics — word/syllable highlighting (BetterLyrics, LyricsPlus, SimpMusic, LRCLIB), tap a line to seek
