I have been fairly successful setting up my own DIY podcast from my home. I use XLR mics, a 8-channel mixer, and record with Audacity.
The next step is adding additional sound elements to the podcast without having to fiddle around with lots of things on the computer. I do have a computer feeding into the mix, but I mainly use this for searching the web, playing the intro/outro, playing songs, etc.
For sound effects, I'd much prefer to have a physical device that is pre-programmed with the sounds of my choice. What are some of the best options for this?
