Fast Sound Library (FSL)

Find the sound. Stay in flow.

Fast Sound Library is a native Windows sound library manager for people who work with large collections of music, samples, and sound effects. Add the folders you already have, search as you type, and audition files without leaving the keyboard.

Search matches file names, paths, categories, tags, and favorites, and it keeps up as the library grows past ten thousand files. Watched folders pick up changes on disk, so the library reflects what is actually there without a manual rescan.

Every sound can be auditioned in place. View waveforms, spectrograms, and animated visualizers. Scrub through a file, loop a selection, change playback speed or pitch, reverse the audio, and isolate individual channels.

Organize with colors and text tags, then collect the results in project bins. Sounds delivered in several formats are grouped into a single result instead of cluttering the list. Export selected clips as WAV, and annotations as CSV or PDF.

Fast Sound Library keeps your files local. There is no account, no cloud service, and no subscription.
