Calculate AcoustID audio fingerprint for a given audio file using the Chromaprint fpcalr tool.

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

Calculates the fingerprint of the given audio file.

File must be the path to an audio file.

Options may be an object with the following keys:

• length: Length of the audio data used for fingerprint calculation (passed as -length option)

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

The fpcalc command-line tool must be installed. This is often available via your package manager (e.g., apt-get install libchromaprint-tools or brew install chromaprint).

npm install fpcalc
