awooler is a free, visual sprite editor and generator for Howler.js. Slice audio files into named ranges, configure every Howler option per sound, preview playback in real time, and export ready-to-use sprite configs for your project.
Drop .wav, .mp3, .ogg, or .flac files into the editor or paste a URL to import audio. awooler runs entirely in your browser — no uploads, no accounts, no server processing.
