Converting Audio into Different Formats / Sample Rates
Minimal example: transcode from MP3 to WMA:

ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:

ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
	<?php

	$start = rtrim($start, '/') . '/';
	}
	if (!empty($start) && !is_dir($start)) {
	return 'json' === $format ? 'false' : false;
