Have yuo tried Gabest MPA audio decoder it also decode AC3 and its quality is superb
And for your knowledge FFdshow is working with me but withh use mp3lib not libmad for both mp3 and mp2 I did not tried it for AC3 " but nvidia works for both and gabest works too for both "
and let ffdshow connected to the default direct sound
No, I haven't tried it. It's not my sound quality that is the issue. My sound quality with nVidia is fantastic. It's the difference in volume levels between providers, and even channels on the same provider sometimes. On Chuck it is much lower than on Beverly, especially on the HD channels.
So when you switch channels between providers, the audio goes from acceptable levels to very loud. FFDShow has a normalizer function that evens out the audio, so it doesn't go from soft to loud when you change channels. This works very well, and it is the reason I need to get FFDShow audio decoder to work with DVB Dream.
I really don't understand why it will work with everything else I have tried it on, but DD refuses to build the graph. I have also often wondered why DD comes with graphedit if I'm not allowed to use custom graphs.
I have read the post about loading the profiles to set FFDShow up for DD, but I can't load the profiles unless DD loads the decoder.
