Streaming music and its challenges

The first days streaming from my home turned out to be pretty tricky since ADSL lines at those times disconnected without warning and on quite regular basis. Moreover, when starting to stream at 128 kbps, the line itself could not be used much for surfing the Net or other heavy down-/uploads. So I decided at once to upgrade my ADSL account to the highest possible within the business sector. I also started to look around for a provider offering shoutcast-server at reasonable prices.

In 2003, bandwidth was costy and many providers charged 4 US Dollars or more per listening slot at 128kbps. I looked at offers in the US as providers in Europe were scares and without much experience within that sector. Providers in Switzerland wouldn't want to offer shoutcast servers as they preferred to sell Real Media & Windows Media Servers at outraging prices.

So I first signed up with Mediacast, Denver, who also ran servers in Chicago and NYC.

As a novice, I didn't know what kind of trouble I would run into when signing up with a provider on the other side of the pond. It wasn't actually the provider itself that turned out to be troublesome - it was the distance between the stream-source and the server.

Tracerts showed hops over 20 POPs and pings were in the 300 ms region which made my stream skipped like hell at 128 kbps. I had to lower the bitrate temporarly and looked desperately for another solution.

After searching for days I came across the provider radiostreamer.com who had their servers located (also) in hamburg. I signed up for 50 slots by paying USD 2.75 per slot. The overall connectivity was okay but quite often the servers went down for various reasons.

So running a webradio like this was kind of a adventure. Anything could happen anytime. The only thing I could really count on at that time was the music automation software I used: OTS JUKE/DJ (AV), the australian built software was rock solid and it hardly ever let me down. It sounded pretty good compared to many other software used at that time having a built in sound dynamic volume processing and an awesome auto mix point detection.

I beefed it up with the DSP OzoneMP by Izotope and the Encoder from Spacialaudio.

The first 3 months I had everything running on a Toshiba Notebook. Then I bought a well equipped PC with loads of RAM so that I had two identical set ups should one of the machines go down. One was used for the actual live-stream, the other (spare) one for ripping CDS, updating the webpage, etc.

All was setup in a 2 bedroom appartment. My girlfriend & I made radio in one room and love in the other, had a small kitchen where we cooked some fine food and an even smaller entree with a round table accommodating 4-5 people. We had all we needed.
