The industry-standard ACCESS from Comrex is a true revolution in audio codecs. Developed from the ground up for use over the public internet, it provides 2-way, stable, stereo, low-delay audio over pretty much any type of internet connection, including wireless systems such as WiFi, 4G and 3G. A pair of rackmounts will provide a superb ISDN replacement whilst the portable unit effectively gives you a radio car in the palm of your hand! It literally is as good as it sounds and is being used by a huge number of broadcasters worldwide.
