Extensible apps for asterisk: Talk Bot • Music Player

This script will convert common AV files (mp3, wav, flac, webm, mkv, mp4) to Mono 8kHz PCM WAV files suitable for Asterisk. Converted files will be placed in a subdirectory named processed.

1. Ensure FFmpeg is installed on your system.
2. Open your terminal, then navigate to the directory containing the audio files to be converted.
3. Copy and paste the script into your PowerShell terminal.

The text being red is not of concern.
