Splitting audio files

Audio files can be split using ffmpeg:

ffmpeg -i input_filename -ss 00:00:00 -t 00:10:00 -acodec copy output_filename

Replace the 00:00:00 following -ss with the start time of the section you want in HH:MM:SS, and replace 00:10:00 after -t with the length of the section you want in HH:MM:SS
