You can do this with the ffmpeg executable included with get_iplayer and a batch file @Echo Off for %%F in (*.m4a) do "C:\Program Files (x86)\get_iplayer\utils\ffmpeg.exe" -i "%%F" -y "%%~nF.mp3" PAUSE save this as a text file in the same folder as your m4a files, but ensure it has a .bat extension e.g. m4a2mp3.bat Then simply double click the .bat file and it will loop through all the .m4a and create a .mp3 with the same filename This will default to a ~128 kbits/s file but if you want to set a different bitrate you can adjust the command in the file. For example, using the LAME V9 preset would give you the following: @Echo Off for %%F in (*.m4a) do "C:\Program Files (x86)\get_iplayer\utils\ffmpeg.exe" -i "%%F" -q:a 9 -y "%%~nF.mp3" PAUSE Full info on bitrates is here: https://trac.ffmpeg.org/wiki/Encode/MP3 HTH Shevek _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
