Convert sid to mp3
Why I have to select length of MP3 file? Some (majority, maybe) of SID files are continuous (those will loop forever with SID player/in original game). There is no easy way to detect such loop - or to decide what is your preference for length of MP3 file.
Conversion is handled by sidplay2 utility. Sidplay 2 is capable of playing all C64 (Commodore 64) mono and stereo file formats, however mp3 files are currently mono only. Stereo tracks will be converted to mono.
