How to analyze MP3 files in Laravel?

We can analyze MP3 files in Laravel by using wapmorgan/mp3info package. The fastest PHP library to extract MP3 meta information and tags.

This class extracts information from Mpeg/mp3 audio:

 

Audio Characteristics	Audio Tags
Duration	Songs
Bit Rate	Artist
Sample Rate	Album
Channels mode	Year
Frames count	Comment
Codec version	Track
Layer version	Genre

Installation

Composer package: wapmorgan/mp3info.

Command to install composer:

• composer required wapmorgan/mp3info

Usage

Step 1:

After creating an instance of MP3info with passing the filename as the first argument to the constructor, you can retrieve the data from object properties.
There are two ways to use wapmorgan.

1. Use wapmorgan\Mp3Info\Mp3Info
   To get basic audio information.

   $audio = new Mp3Info(`filename`);

   If you need parse tags, you should set a 2nd argument.

   $audio = new Mp3Info(`filename`, true); 

2. Another way
   Install the composer and add the code in the respective method.

   composer required wapmorgan/mp3info
   $audio = new \wapmorgan\Mp3Info\Mp3Info($filename, true);

Step 2:

After that access object properties to get audio information.

$audioDuration = ‘Audio Duration’.‘:’.floor($audio->duration);
$audioBitRate = ‘Audio Bitrate’.’:’.floor($audio->bitRate);

You can also find other audio characteristics by following step 2.

To find the Audio tags:

Step 3 (If required):

To access id3v1 tags use $tags1 property. To access id3v2 tags use $tags2 property.

For Simple id3v1 tags,

$audioTagSongs = ‘Songs’.’:’.$audio->tags1[‘song’].’from’.$audio->tags1[‘artist’];

For specific id3v2 tags,

$audioTagSongs = ‘Songs’.’:’.$audio->tags2[‘T1T2’].’from’.$audio->tags2[‘TPE1’];

List of API 

Audio Informations:

Property	Description	Values
$codeVersion	MPEG codec version	1 or 2
$layerVersion	Audio layer version	1 or 2 or 3
$audioSize	Audio size in bytes. Note that this value NOT equals file size	Int
$duration	Audio duration in seconds.microseconds	Like 3603.0171428571 (means 1 hour and 3 sec)
$bitRate	Audio bit rate in bps	Like 128000 (means 128kb/s)
$sampleRate	Audio sample rate in Hz	Like 44100 (means 44.1KHz)
$isVbr	Contain true if audio has a variable bit rate	boolean
$channel	Channel mode	‘Stereo’ or ‘dual_mono’ or ‘joint_stereo’  or ‘mono’
$tags1	Audio tags ver.1	[“song”] => “song name”, “year” => 2020
$tags2	Audio tags ver.2, only text ones.	[“TIT2” => “Long song name”,…]
$tags	Combined audio tags (from id3v1 & id3v2). Keys as in tags1.	[“song” => “Long song name”,”year” => 2020,…]
$_parsingTime	It contains time spent to read & extract audio information in sec.msec

 Performance

1. Typically it parses one mp-3 file with the size around 6-7 MB in less than 0.001 sec.
2. List of 112 files with constant & and variable bitRate with total duration 5:22:28 are parsed in 1.76 sec.
