Rubber Ring Reproductores de música app para Android
Rubber Ring is a tool for practicing song parts. Pick an audio file, mark a start/stop region on its waveform, and play it back in a seamless, gapless loop. It auto-detects tempo and beats to snap the loop markers to a beat grid, with full manual override.
Early-stage release — expect rough edges. Feedback and bug reports welcome via Issues.
Features:
- Import-and-own library — picked files are copied into app-private storage, so loops never break when the original is moved, renamed, or deleted.
- Waveform region selection with gapless looping — drag start/stop handles to mark a section; the loop boundary wraps with zero audible gap or click.
- Automatic, hand-editable beat grid — a dependency-free estimator finds BPM and a downbeat, and handles snap to the beat grid.
- Chord detection with a hand-editable chord lane — chords are labelled over the waveform; tap to relabel, split or merge, and drag a boundary to nudge it. Detection is tuned to the authors own material, so the lane is there to correct by hand, and can be turned off.
- Per-track audio normalization — boost a track that was mixed too quietly, by peak or by loudness; your original file is never altered.
- Adjustable playback speed — slow a tricky passage down (or speed it up) without changing pitch.
- Count-in — long-press Play to start after a metronome counts you in at the tracks tempo.
- Saved loops and practice arrangements — capture named sections per track and chain them into a sequence, each repeated as many times as you set.
- Backup & restore — export your whole library (tracks and saved loops) to a file and restore it after a reinstall or on another device.
- Light & dark themes, follow-playhead scrolling, and a recents list.
