Okay... I take it back on audio quality. WBAP-FM is loud again.
I put WBAP-FM on just after my initial post, and the audio quality / perceptual loudness was completely back to normal as in its normal pre-relocation loud. Sufficiently loud enough for Dallas as compared to my other presets. It would seem that someone smoothed out the audio problem
before I posted my last. Thank you. It had been low over the past weeks.
As for the liabilities of clipping-
More clipping isn't the answer, for greater clipping shortens time spent listening, and when TSL drops, a station's in trouble. You can't reach or recycle audience if they're not listening long enough to hear your message.
I believe that the rationality of that argument, processor fatigue, might best apply to TSL for music formats, but is not necessarily true and valid for MONO FM all talk programming. I just don't know that the same logic (artifacts of processing on pure voice degrading TSL) applies to voice only programming, on FM or AM. And there is the separate issue of WBAP-FM being a 'rim shot' station, located 65 and half miles from Cedar Hill.
In the sense of my original comment, flipping between presents had dramatically revealed that WBAP-FM was much lower as compared to the stations on my other presets (a problem which has been fully corrected). A perceptual difference in loudness is much more pronounced, and much more a tune out / tune off / tune away factor, especially for an FM Talk station, than the amount of clipping applied, be it MB clipping or Final Drive Clipping.
Additionally, a you'd think (ahh, I'd think) that a conventionally processed / conventionally clipped FM Mono station should be equivalently loud or even louder than it's stereo counterparts by virtue of simply eliminating the 10% loss from pilot injection.
For many years, I was the chief for the other station on that tower, 101.7 / KZMP. I signed it on. From that experience it was my discovery that adjusting the processing in Decatur for aural quality in Dallas, 60+ miles away, should be done with respect to the stations aural performance in Dallas, not at the base of the tower. That is, the amount of clipping employed was based upon how the station sounded in traffic at 35 @ 635, Central Expressway, etc, NOT how the station sounded inside it's 70 dBu contour. As such, it was necessary to employ clipping to achieve the proper competitive loudness for receive signal levels which were at or significantly less less than 54 dBu.
In that time, using an A-B comparison with 96.7 (then Memories, KMEO, now WBAP-FM), the density of 101.7 also created a perceptual and competitive advantage in 'rim shot' performance of 101.7 vis-a-vis a perceived improvement in signal to noise. In other words, a loud 101.7 was perceptually better aurally than 96.7 because the loudness, including undesired artifacts of clipping, masked many of the pops and clicks and hisses that plagued KMEO in the same far distant reception areas. This is a different trade off than loudness versus distortion (valid in the 70 dBu), the trade in rim shot operation is loudness & dirtortion versus a listener's perception of noise.
Would I have added clipping to KMEO given its format? Again, perhaps not the best decision for the Memories format, and definitely not with a Memories format at Cedar Hill, but if it improved the perception of aural quality and S/N over Dallas from Decatur... then definitely.
It's all about listener perception, so beside the all talk Mono FM issue to consider, to get the correct listener perception, doing processing and balancing trade-offs in processing a 'rim-shot' station is wholly different as compared to processing at Cedar Hill.
If I had to guess, I'd bet the amount of clipping on WBAP-FM is set the same now as it was before the move (which certainly was and is adequate to be competitive in Dallas). And, I'd guess that the STL drive levels had been inadvertently lowered by or during the move. Again, a problem that was corrected even before my original comment posted herein.
