Node.js Audio Recorder

node-audiorecorder is a Node.js module designed for recording audio, delivering a 16-bit signed-integer linear pulse modulation WAV stream. It acts as a wrapper around external system utilities like SoX ('rec' or 'sox' commands) or ALSA's 'arecord' utility, which must be installed and available in the system's PATH. This package is currently at version 3.0.0 and offers robust control over recording parameters such as sample rate, bit depth, channels, encoding, and silence detection. Its primary differentiator is providing a programmatic interface to common command-line audio recording tools, making it suitable for applications requiring real-time audio input processing or storage. While its release cadence appears sporadic based on recent releases, the latest major version indicates ongoing maintenance and improvements.
