Thoughts on the new StreetJelly.com “Jellycaster” stereo broadcasting process (and optional simple stereo set up).

Overview:
The StreetJelly.com stereo broadcasting system nicknamed “Jellycaster” not only supports stereo broadcasting but it supports such broadcasting in exceptional high fidelity. I believe it is as good or better than you will have available on any other streaming sites. On StreetJelly, we have a very varied group of performers with different ways of presenting their music and all will benefit from this excellent available sound process.

For example: Some musicians add pre-recorded stereo background tracks from commercially available software programs such as “band in a box” or even separate drum machines. Some performers like adding effects such as reverb, chorus and vocal harmonizers. All can be done with varying amounts of complexity and all can sound great when heard via the Jellycaster.

My own simple stereo set up:
In my particular case, I use two microphones in a simple stereo setup called an XY configuration (described well in the Shure stereo microphone tutorial link below). I set up the microphones about chin level and two feet away to pick up my guitar and vocal as one stereo signal. Please note: I am by no means saying it is the best way to go but it just works for me and is simple to set up for acoustic musicians/singers. It also is a very pure stereo signal.

Getting a simple stereo set-up into the computer:
Some choices for transferring this type of simple stereo broadcasting into the computer are: 1) Use a USB audio interface, containing some good mic pre-amps and good analog to digital converters (Mackie, M-Audio, Pre-sonus and other companies produce these). They are now relatively inexpensive A simple two channel version is about $100-$200 U.S.. 2) Use one of the nice USB stereo microphones available today for a reasonable price, or 3) Buy a small format USB mixer that has at least two channels equipped with simple one knob compressors and effects (most importantly reverb).

My recommended option:
For the simple type of stereo set up as described herein, I recommend option 3). It gets you all the basic variables that are most important for good sound. Companies such as Yamaha, Behringer, and Samson make stereo USB mixers for $100-$200 U.S. equipped as described herein. This allows you to to apply some reverb for a little ambiance to all Channels (usually 4-12 in small format mixers). That said, all you need for an XY set up are two channels with a little stereo reverb and some simple compression (to make the overall sound a little fuller and tame the peaks a bit).
Below, is a link to Samson’s YouTube video describing their models just to give a nice idea of the essential features. Note: all the brands have nice microphone pre-amps on these models nowadays.

Summary:
Again, this is just a recommendation for getting there simply. More elaborate set-ups will sound wonderful on the Jellycaster as well. Contact me if you want any help setting up such a simple system at billhall@billhall.us

Thanks to Frankie and Martina for getting this great Stereo option in place.
