audio-conversion-queue

Convert audio files temporarily, on the fly.

Installing

npm install audio-conversion-queue

Usage

const createConversionQueue = require('audio-conversion-queue')

const queue = createConversionQueue()

queue.convert('/path/to/audio.m4a', (err, dest, purge) => {
	if (err) return console.error(err)

	console.info('the converted MP3 file is at', dest)
	// do something with the file…
	// when you don't need it anymore, delete it:
	purge((err) => {
		if (err) console.error(err)
	})
})

API

const queue = createConversionQueue(srcToDest = defaultSrcToDest, ffmpegArgs = ['-acodec', 'mp3', '-format', 'mp3'])

Pass a custom createConversionQueue(src, cb) function that, given the source path src (e.g. /path/to/audio.m4a), calls cb with the path of the MP3 destination file (e.g. /path/to/audio-4f2f.mp3). You could also use the hash of the source file.

Pass an array of strings for ffmpegArgs to customize the conversion. Refer to the ffmpeg docs for details.
