Soundfile Conversion Software ?, Looking for a up Pro-Software for MAc Options

I am searching for a new pro-software to convert audio files.

I use Media Cleaner 6 at the moment; this is designed for the needs of Film, so a lot of the telephone-formats are missing.
There was a great converter "Barbabatch" from www.audioease.com, which was updated the last time in the year 2000.

So if anybody has an idea for such a professional software, please contact me.

Thanks,


Michail [B]
