Refining Radio Delivery
Audio Streaming: A New Approach - $15
Date: April 26, 2020Topics: 2020 BEITC Proceedings, Refining Radio DeliveryMost of your streaming audience wants something that just works reliably; they don’t care about the tech behind it. Many audio streams currently in service fall short. However, it is up to the content providers to make it work. If you stream audio, you need to know about this. This information is targeted to streaming professionals.
This paper/presentation describes a standards-based method of quality live streaming audio with dramatically decreased operating costs, increased reliability, professional features, and a better user experience. Streaming audio has now evolved past legacy protocols allowing reliable content delivery to mobile and connected car dashboards, where all the audience growth continues.

Comprehensive Study Of FM Multipath With Repeatable Results - $15
Date: April 26, 2020Topics: 2020 BEITC Proceedings, Refining Radio DeliveryMultipath is an unknown variable in FM broadcasting, and quite possibly the largest annoyance for listeners. Due to momentary changes in FM signal propagation, multipath is extremely difficult to measure in a repeatable manner. On account of this, it becomes difficult to rely on captured measurements to confirm or deny the effects of multipath, when evaluating FM coverage. Additionally, signal processing can affect, or aggravate multipath in a negative manner.
Today, there are software tools available which are capable to simulating the FM signal path, as well as generating multipath. Due to the controlled environment the software system provides, creating repetitive propagation profiles, as well as synchronized signal content profiles, enables the ability to generate, transmit, and measure FM multipath situations. The testbed provides results which are repeatable, as well as confidence in the data that was acquired.
This paper will detail and illustrate work that was done using MatLab as a testbed, in this study of multipath. Employing good engineering practice, it will also provide audible examples of the effects on multipath as caused by various signal processing methods such Single Sideband Suppressed Carrier (SSBSC), and dynamic limiter functions of the FM-Stereo system. This is no ad-hoc drive up a coastal highway!
