Codecs

Recording using codecs:

Recording using codecs has been tested and should work properly. Nevertheless not all of the codecs which you can see in the selection dialog are suitable. 
The table shows several configurations of computers, operation systems and codecs that have been tested.
Some codecs or combination of codec and its parameters are supposed to be used for decoding only so they would not work for recording.
If you try codec (in Radiator) which creates wave file that is not able to be played, it is necessary to close Radiator and start it again, or it would create not playable file even with codecs that should work. 

I'll be glad if you send me test of other codecs or other configurations if it should differ from the following table.
