We use your Auto dj system with full confidence and satisfaction.
I think with an extra feature for your product like a audio processor would take a new step.
I meet the company/owner Hans van Zutphen of Stereo Tool. We use his audio processor for other radio automation projects before the encoder/stream. http://www.stereotool.com/
I talk to him he have already audio proccesing for Linux systems. And there is media project that use Stereo Tool for more than 100 streams.
He told me the have a special plugin-type to try it.
I know the server need more CPU, but this is option to sell.
We think the use liquid soap (for better crossfading) not sctrans2 and use Stereo Tool. The not need any other radio automation program!
