October 18th Meeting: Wheatstone HD Audio Alignment and Other Tricks

Keeping your FM station’s IBOC digital audio time-aligned with your analog audio has been a source of frustration since digital was introduced. At one time, this meant manual adjustments until you could no longer perceive the difference, perhaps using a headphone with one stereo side in digital and the other in analog. Then along came separate boxes to attempt alignment, but that introduced another single point of audio failure into your system.

Wheatstone’s Mike Erickson, one of the country’s most renowned processor experts, discussed at our October 18, 2017, meeting the AirAura processor and how it addresses HD time alignment and other FM challenges with a correction input from a Belar monitor. We also discussed processing as it relates to the reduction of FM multipath.

In Chapter 36 business, we discussed the recent survey and how it related to occasional low meeting attendance. Officer elections are next month. It’s a good time to step up and try your hand at leadership positions. Contact Gary Stigall.
