## What is TempoBench?

Put the song on your workbench, slow it down, and hear every note.

TempoBench is a practice player built for musicians who transcribe by ear. Import an audio file or record a rehearsal, play it back at 25%–200% speed without changing the pitch, loop the tricky bars seamlessly, and zoom into the waveform to land exactly on a phrase.

Features:
- Time-stretch: 25%–200% playback speed, pitch stays put; changes apply instantly without interrupting playback
- Pitch shift: ±12 semitones in steps, plus ±50 cents fine-tuning for off-pitch recordings; fully independent from speed
- AB loops: tap in/out points for a seamless loop, nudge endpoints by milliseconds; save unlimited named loop regions, each remembering its practice speed
- Waveform navigation: tap or drag to seek, pinch to zoom 1–16x
- Flexible import: mp3 / m4a / wav / flac and more from the Files app or cloud drives; or record straight into the library
- Practice memory: position, speed, pitch, loops and notes are saved per track and restored next time
- Background playback with full Lock Screen and Control Center support

Pricing, honestly: every feature is free and the library has no track limit — speed, pitch, AB loops, recording and saved regions are all included, with no paywalls anywhere. A single banner ad sits at the bottom of the screen; if it bothers you, a one-time Remove Ads purchase takes it away. It does not unlock anything new. No subscription, no account.

Privacy: your audio, recordings, loop regions and notes all stay on this phone and are never uploaded. Practice works fully offline — the bottom banner is the only thing that needs a connection. No tracking, and no App Tracking Transparency prompt.
