My tinnitus causes intermodulation distortion. Earlier this summer, I went to a concert at St. Agnes Cathedral (Rockville Centre, NY). All volunteer orchestra and the all volunteer Cathedral Choir performed Beethoven's 9th Symphony. They did surprisingly well! I also got to sing with the Cathedral Choir and a pro brass sextet for the ordination of three priests. There is nothing like live music.

Music, especially classical music is hard to listen to on AM. I wonder if some of this is due to overmodulation, distortion due to the carrier frequency being low enough to still be imposed on the audio after demodulation. (All the textbooks show the carrier and a sine wave at audio frequency before detection, and only the sine wave but with "saw teeth" after demodulation.) Before Armstrong invent FM, there was, for a short period of time, the "Apex" band somewhere around about 40 some-odd MHz, where the separation between stations was much wider than the broadcast or shortwave bands. I wonder what the fidelity was, in comparison to FM. If all else was equal (bandwidth, etc.), does FM provide better fidelity and lower distortion due to FM vs AM or is FM's only advantage freedom from static, lightning and other atmospheric noise that can amplitude modulate a carrier?
