Playing alto 2 1/2 years
Pardon me for playing devil's advocate, I sympathize, but the opposing argument for an 8-hour recording is how easy that would be to fake. The recording itself may convince a human that, "Wow that would be awful to live through daily". The eight hours part, it's not obvious but I'm pretty sure if you pay attention to the compression (mp3 low quality) you won't have trouble. Anything that records will do that.
