Hi end frequency hiss

I record at 24bit & a 48.0 sampling rate
When I bounce everything to a stero mix I need to dither it to 16bit & 44.1, so i can make it red book standard, burn it to a cd or make an mp3. Thats where the hi end frequency hiss comes from.
What do I do ?

I made some tracks for a friend's hip-hop project (I did the music, he did the MCing). He was taking it to a well regarded masterer -- sorry, don't know the name, but masters the tracks on all analog equipment (not that this is necessarily better, but just sayin' he's not "some guy" who just bought pro-tools, he's apparently been doing this a very long time).
I was instructed (read "told with great emphasis, several times") to deliver 24bit 44.1 files. My friend the audio engineer said it was likely 'cause dithering down from 96 to 44.1 wasn't the greatest move. Don't know if that helps. I don't get it, somewhat. Maybe you should sample/record at 24/96 and output the finished track at 24/44.1 before you hand it over.
Dunno. I'm a great help.
All I can say is that if you don't know what the problem is, maybe you should have a professional master it. It'll cost (my friend is paying $450 and hour), but the results should be wonderful if you find the right guy!

If the target medium is CD you should record at 44 or 88Khz because converting from 48 results in rounding errors. Everything about masters & dither & bitdepths here:

I was told by a great engineer that 24bit 44.1 is the way to go.

What did you use for dithering ???
And for Samplerate conversion ?
