This may not be a BIAB question at all (or it may be!). Here is a link to a recording I did in Audacity. I directly took the Rendered output of BIAB and imprted this into Audacity. I then recorded my guitar (which is attached to the PC by LightSnake cable) over this BIAB output. I then output the result to an MP3. I also uploaded this to Soundcloud which is here:

The quality is really lacking I don't think it is Soundcloud because I listen directly to the original (output from Audacity) MP3 and both the guitar and the backing track are fuzzy. Any idea what the issue could be?
