README

This package is a wrapper for the fpcalc command-line tool.

Installation

First you need to get installed fpcalc on your system.

OS X

brew install chromaprint

Ubuntu

apt-get install libchromaprint-tools

Arch Linux

pacman -Sy chromaprint

Or you can get the latest version from AcoustId site

Than you just need to require this package via Composer

$ composer require mrfeathers/php-fpcalc

Usage

Usage is pretty simple. First you create a FpcalcProcess using factory class.

$factory = new FpcalcFactory();
$fpcalcProcess = $factory->create();

Than just call generateFingerPrint with array of file paths (or web stream uri - more info)

$result = $fpcalcProcess->generateFingerPrint(['myfile.mp3']);

//or you can generate fingerprints for more than one file
$result = $fpcalcProcess->generateFingerPrint(['myfile.mp3', 'mysecondfile.mp3']);


//using online stream radio
$result = $fpcalcProcess->generateFingerPrint(['http://icecast2.play.cz/radio1.mp3']);

As a result you'll get output string with generated fingerprint or fingerprints.

You're able to set some options:

• format - input format name
• algorithm - algorithm method (default 2). Available since fpcalc version 1.4.3
• rate - sample rate of the input
• channels - number of channels in the input audio
• length - restricts the duration of the processed input audio (default 120, in seconds)
• chunk - splits the input audio into chunks of given duration (in seconds)
• overlap - overlap the chunks slightly to make sure audio on the edge id fingeprinted
• ts - output UNIX timestamps for chunked results, useful when fingerprinting real-time audio stream
• raw - output fingerprints in the uncompressed format
• outputFormat - format of result output. Available: json, text, plain

Sometimes fingerprint generation can be a long process, sou you can set the process timeout using setTimeout method (default is 60 seconds).

Feel free to open an issue in case of bugs or improvement requests!
