I want to use Adobe Media Encoder as my all in one media converter, even for audio files. but currently it doesn't have a m4r support, both for import and export? Where can I download this codec? Or if possible, how can I just make this encoding preset, please guide me. This is important to me since I want to convert iPhone ringtones using Adobe only.
Also if possible, where could I install more audio codecs. There's an abundance of built in video codecs, but not on audio. Where can I find them? And where can I find more codecs, both for video and audio for AME if I want them?
