This JavaScript library provides a complete solution for playing, recording, and converting AMR audio files entirely in the browser without server support. It's built on amr.js and RecorderJs, offering a simple API for initializing with URLs, blobs, or recording directly, with features like playback control, event handling, and format conversion. The project is aimed at developers building voice messaging features, particularly in chat applications, who need lightweight AMR audio support without external dependencies.
