Application Notes: Testing Audio Quality in Live Radio Broadcast

The radio broadcast signal chain is a long and complex path involving electro-acoustic transducers, mixers, storage media, interface channels, signal processing and more. Each process within this path can induce distortions upon the original audio signal, even when working correctly. These distortions can become intolerable when devices fail or are incorrectly configured or interfaced, and should therefore be analyzed both at the installation stage and also during ongoing use. This paper discusses some methods for achieving this.
