What's new v0.12

• Export a saved loop as a WAV file: long-press its chip and choose Export as WAV. The file is the loop as you hear it, at the current speed and cut exactly at its edges.
• Loops played slower or faster than 1× now come round exactly on time instead of a few milliseconds early, so they no longer stumble at the loop point.

About Rubber Ring

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. Detection is tuned to the author's 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 track's 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.
• Export a saved loop as a WAV file, at the current speed, for a DAW or to share.
• Backup & restore — export your whole library to a file and restore it after a reinstall.
• English and German, with optional German note names (H and B) for chords.
• Opens audio shared from other apps.
