API

var AudioBufferStream = require('audio-buffer-stream')

var stream = AudioBufferStream(opts)

Create a transform stream that accepts AudioBuffer objects written in and outputs a raw PCM stream as buffers.

opts

• bitDepth: specify the bit depth of the output stream (16 or 32)
• channels: number of channels interleaved in the output stream (defaults 2)
• chunkLength: avoid tying up the event loop by specifying a max per tick (defaults 256)
• opt.silenceDuration: when specified (> 0) will remove silences greater than specified in seconds.

stream.write(audioBuffer)

stream.pipe(destination, opts)

stream.setSilenceDuration(seconds)

stream.end()
