If its of any use then 56kbps in mono is not too bad. As its doubled for stereo, ie if it was stereo then it would be 112kbps, so not to far short of the 128kbps for supposed CD quality...

Although to my ears, I can occasionally here clipped high hats on a 128kbps mp3. So always try for 160 or 192, which if I was going to host it for downloading I would turn into mono as for the most part there's little point in having a techno mix in stereo...

I checked yesterday and Jerome's mix at Pure Filth generated approximately 5gb of traffic per month on the Pure Filth site, thank the lord for Blueyonder's unlimited bandwidth deal... although I am doing my best to get a phone call from them to cease and desist for abusing the deal... :-)
