We designed, implemented and deployed a custom e-radio system consisting of transmitter, relay network and a desktop player.

The transmitter used high quality audio files saved in lossless FLAC OGG format, while the end-user codec was a low-bandwidth AAC Plus v2. Despite (quite high) license fees usually required to stream and play the latter format, we were able to use an architecture which carried no license costs and was legal.

Additional cost reduction was possible due to network bandwidth fee optimization using dedicated servers from international datacenters.

Savings achieved this way summed up to $50.000 per month, making the entire project viable. This is how the first e-radio of such size in the world was born.
