Fast Sound Library (FSL)
High Performance Audio Library
Only for Mac
Free
Mac
Fast Sound Library is a high performance and lightweight library for organizing your music and sound effect assets.
The app is written from the ground up with nothing but native code and is GPU accelerated. With no WebViews, cloud features, sign ins or subscriptions, it focuses on only one thing: A fast focused environment to sample and organize audio files for your video, game or any other artistic production project.
Load your audio asset folders by dropping them on the app and defining them as Watch Folders. Any update in the folder is automatically picked up by the app.
You can listen to a variety of formats (expandable if you allow it to use FFMpeg,) assign colors or tags to them. You can create stashes for your projects and gather suitable audio assets for each project individually. And you can export annotations to CSV or even PDF.
With beautiful visualizers, spectrogram and wave form rendering, you can enjoy the feeling of the music assets you listen to. You can also export parts of an audio file into clips, adjust the pitch and speed all within FSL.
FSL allows you to categorize sound track files to specific bins for each of your projects.
