What is web-audio-recorder-js?
WebAudioRecorder.js is a client-side JavaScript library that captures audio from Web Audio API sources and encodes it into downloadable audio files directly in the browser. It solves the problem of needing server-side processing for audio recording by providing efficient, in-browser encoding to WAV, Ogg Vorbis, and MP3 formats. The library uses Web Workers to handle encoding tasks, ensuring the main thread remains responsive for a smooth user experience.
Frontend developers and web application creators who need to implement client-side audio recording features, such as for voice memos, podcast recording tools, or audio annotation applications. It is also suitable for projects requiring browser-based audio processing without server dependencies.
Developers choose WebAudioRecorder.js for its multi-format support (WAV, Ogg Vorbis, MP3) and efficient Web Worker-based encoding that prevents UI blocking. Its configurable options, like bit rate, quality, and encoding modes, offer flexibility not always found in simpler alternatives.
