README

PHP-MP3 is a simple library for reading and manipulating MPEG audio (MP3).

This library is based on a similar project with the same name written by thegallagher which it-self was based on an script from regin.

This is not an encoder or decoder and therefore can't change the MP3 properties like bitrate, sample size, and sample rate. It's a MPEG Audio parser and therefore it should only be used to modify/create/read valid MP3 containers.

How to get

You can install and use this library with composer:

composer require falahati/php-mp3:dev-master

Features

• Correctly identifies MPEG Audio Version 1, 2 and 2.5
• Correctly identifies MPEG Audio Profile 1, 2 and 3
• Correctly extracts bitrate and sample rate information
• Correctly calculates MPEG Audio stream duration
• Frame address recovery allows the code to correctly parse corrupt data
• Trim (Cut) a MPEG Audio data and merge multiple MPEG audio streams
• Ability to strip MPEG Audio data from starting and ending ID3 (or similar) metadata information

Samples

Strip ID3 tags from a MP3 file:

\falahati\PHPMP3\MpegAudio::fromFile("old.mp3")->stripTags()->saveFile("new.mp3");

Cut a MP3 file to extract a 30sec preview starting at the 10th second:

\falahati\PHPMP3\MpegAudio::fromFile("old.mp3")->trim(10, 30)->saveFile("new.mp3");

Append memory stored MP3 data to the end of a MP3 file:

\falahati\PHPMP3\MpegAudio::fromFile("old.mp3")->append(\falahati\PHPMP3\MpegAudio::fromData(base64_decode("/**BASE64-DATA**/")))->saveFile("new.mp3");

Extracting MP3 file total duration:

echo \falahati\PHPMP3\MpegAudio::fromFile("old.mp3")->getTotalDuration();

To Do List

• Add Unit Tests
• Ability to load and manipulate data directly from, and to a resource
• Ability to add simple ID3 metadata information to the MPEG Audio before saving
