Hello!

Does something like this exist for Delphi?

http://code.google.com/p/dsbridge/

http://sourceforge.net/projects/audorra/

Hello!

That is completely diffrent that I requested

"DSBridge is a small wrapper application that redirects the DirectSound API and exposes the playing stream as an MP3 stream with metadata."

Also why ignore english users??

No one is ignoring you, it's just that media applications are rarely made in Delphi, hence there is a comparably little (but notably existent) pool of related third party components/libraries, and also not too many people invested in it, which could provide valuable information. They exist, but usually one has to look harder compared to C(++)/#, Java and the other usual suspects.
Secondly, you do not "request" in a forum. You may "ask for kindly" .

It is very well possible, that what you are looking for simply does not exist in that form. Audorra however, I only know it by hearsay, seems to provide an interface to DirectSound at least, so it could serve as a good basis for your own effort to mold something that does what you need, at least. It may even provide more, since I gathered that it is a rather big lib, which may hold some functions that are not that obvious at first glance.
The functionality you seek sounds quite custom, so I would be prepared to invest some time to create something similar myself, if I were you. Building blocks like Audorra however can be of great help with this, so that info wasn't useless by far.
