I posted several months ago on converting ACT files recorded on an MP3 player to something readable on a computer. It’s probably without competition the most-read and commented-on post on this site: there are many people out there who are looking for a tool to do this. And it seems that the ACT files generated by newer MP3 player devices aren’t compatible with the older convertors.
So, one of the readers, Phil “Mumbles”, discovered a tool that works for this stuff. He’s sent me the file after having cut it down from 8MB for a few apps to under 300KB for the just new sound convertor tool.
You can download it here — please post if it works or doesn’t work with your MP3 player/recorder so that other people looking for information on their device can find it.
One closing note from Phil:
It appears to hang if you don’t let it run its course (gives a not responding msg). the “hang” grows accordingly with the .act file size.
