A week ago or so while I was in the waiting room of the carwash I read on a magazine about I-Doser. A company that sells virtual doses to stimulate your brain and put it into similar state than recreational drugs, in their store you can find all kind of crazy stuff.
The only problem is that they use a closed format to publish their doses (.drg) and they can only be played with their program, which means that you need to be close to the PC or buy a wireless headphones. They do provide some mp3 files, but the list is not as big as the drg.
They use SBaGen to generate the Binaural tones, SBaGen is an open source application and it can send the tones to an audio device or to a wav file.
The guys from The Unofficial I-Doser Blog managed to break into the .drg file (which is a base64 + RC4 encoded file) and extract all the parts of it (Info, Image and SBaGen sequence file), with the SBaGen sequence file it’s possible to play it on SBaGen and send it to a .wav file.
It’s not recommended to covert it to an mp3 file, since the compression process can affect the tones reducing or annulling the effect of the dose. So it’s better to use the .wav file, with todays portable player space this shouldn’t be much of an issue. Even so people says that a bitrate of 320 gives good results (haven’t tried it).
And for those of us that only use Linux, I have port the decoding part of the Stealth’s DRG Author (which is a Visual Basic application that runs on Windows), with it you can get the .sbg file out of th .drg and convert it to .wav using SBaGen. The project is hosted in google code and you can access it here.
Feedbacks and contributors are welcome, if you like to extend or improve it, please join the project. Also don’t forget to read the README file.
I’ve done the same thing and used their code to create a batch DRG to SBG converter for windows.
