Can you give me some information about using afconvert in iPhone to convert file formats? Or let me know some links that give me basic information on afconvert. I want to know the commands used - what do -f, -d , -c etc. stands for in:
afconvert -f aac -d mp3 [input] [output]
Where do I mention the source data format, file format and destination data format, file formats in the above command?
