Ch 680, Chester county pa. Noticed at least a couple of days ago. Sound it’s much lower than other channels and doesn’t sound right on my 5.1 system. I didn’t notice the other channels I watch have this problem.
There is a LOT of channel to channel variation in the audio quality from broadcasters. Some shows are stereo, some Dolby Digital and some DD5.1. Also the levels of compression vary from channel to channel, and Verizon adds their own compression to the mix. Some broadcasters use very high levels of compression on their commercials, making them sound FAR louder than program material even though they MEASURE legal. SiFy may have changed their processing to do exactly that, which results in low audio levels for programming and high levels for commercials.
