How to create .AA files?

[coyotewrw]

Hi,

I've successfully used dbA to convert Audible .aa files to .mp3, but is there a way to go in the other direction: WAV, Mp3, etc. to .AA?

Thanks!

Its not possible using dMC. As for other programs, I am not sure. If they do exist, they are probably expensive.
