What are the alternatives to MP3 format for encoding audio recordings in PHP applications, considering licensing constraints?

When considering alternatives to MP3 format for encoding audio recordings in PHP applications due to licensing constraints, one option is to use open-source formats like Ogg Vorbis or FLAC. These formats provide high-quality audio compression without the licensing restrictions associated with MP3. By using these alternatives, developers can ensure compliance with licensing constraints while still delivering audio content in a suitable format. 

// Example code snippet using Ogg Vorbis for audio encoding in PHP
$audioFile = 'input.wav';
$outputFile = 'output.ogg';

exec("ffmpeg -i $audioFile -c:a libvorbis $outputFile");
