What are the potential challenges of creating an audio stream using PHP?

One potential challenge of creating an audio stream using PHP is ensuring that the audio file is properly encoded and streamed in a compatible format. To solve this issue, you can use a library like FFmpeg to convert the audio file to a supported format before streaming it. 

// Example code using FFmpeg to convert audio file to MP3 format
$audioFile = 'input.wav';
$outputFile = 'output.mp3';

exec("ffmpeg -i $audioFile -codec:a libmp3lame -qscale:a 2 $outputFile");

// Code to stream the converted audio file
header('Content-Type: audio/mpeg');
header('Content-Length: ' . filesize($outputFile));
readfile($outputFile);
