    fpcalc

    This module is a wrapper around the fpcalc command-line tool and provides a node interface to calculate AcoustID audio fingerprints for audio files.

    Installing Chromaprint

    fpcalc (provided by Chromaprint) must be installed for this module to function.

    OSX using Homebrew

    $ brew install chromaprint
    

    Ubuntu

    $ sudo apt-get install libchromaprint-tools
    

    Example

    var fpcalc = require("fpcalc");
    fpcalc("./audio.mp3", function(err, result) {
      if (err) throw err;
      console.log(result.file, result.duration, result.fingerprint);
    });

    API

    fpcalc(file, [options,] callback)

    Calculates the fingerprint of the given audio file.

    File must be the path to an audio file or a readable stream.

    If using a stream, note that you will not get duration out due to an fpcalc issue.

    Options may be an object with any of the following keys:

    • length: Length of the audio data used for fingerprint calculation (passed as -length option)
    • raw: Output the raw uncompressed fingerprint (default: false)
    • command: Path to the fpcalc command (default: "fpcalc" - expects executable in $PATH)

    Callback must be a function that will be called with callback(err, result) once the fingerprint is calculated. The result object will contain the following keys:

    • file: Path to the audio file
    • duration: Duration of audio file in seconds
    • fingerprint: Fingerprint of audio file - Buffer if options.raw, String otherwise
