Convert Audio files to .flac format using php code

Question

I have audio files on my server and wanted to convert them into flac format in order to convert them into text. Please let me know how can we achieve that..

Answer 1

You can use FFmpeg: https://ffmpeg.org/

ffmpeg -i input.mp3 output.flac

There is a php wrapper for the ffmpeg binary on github. https://github.com/PHP-FFMpeg/PHP-FFMpeg

Answer 2

In case you can't install ffmpeg you might want to try this free API:

<?php
$url = 'http://server.com/sound.mp3';
$data = json_decode(file_get_contents('http://api.rest7.com/v1/sound_convert.php?url=' . $url . '&format=flac'));

if (@$data->success !== 1)
{
    die('Failed');
}
$flac = file_get_contents($data->file);
file_put_contents('sound.flac', $flac);
