About this Tool
The audio-player tool on AllThatConverter plays and loops audio files with a zoomable waveform, and allows cropping selected ranges to high-quality MP3 tracks with custom loop repetitions and silent intervals. Every single operation operates locally in-browser via native Web Audio APIs, keeping your files completely secure and eliminating network transfer latency.
