> I would venture that almost no one else in this thread would watch that video and call that an all-caps HUGE amount of noise. I listened to the video and while I wouldn’t go all-caps, it’s way more noise that I like to listen to. So I downloaded the audio track and measured the RMS noise and signal levels, getting about a 30dB SNR. That’s a somewhat bad number, which matches my subjective experience. A few years ago I converted some old audio cassettes with voice recordings of deceased family members to MP3. I heard all sorts of weird noises, but I spent a while getting rid of them with EQ and notch filters. I don’t know if anyone else in the family cared about the work I did cleaning up the audio, but I did. Everyone has different standards, and it’s not quite fair to say that nobody in the audience cares about these things, just like it’s not quite fair to say that everyone in the audience cares. |

Yeah just casually comparing it to other random videos and podcasts, IMO it's really noticeable.
I was going to post a screenshot comparison of that between all 3 videos but it's probably not worth the effort. It's tricky to compare just by hearing because headphone quality plays a massive difference. On some headphones you can't hear anything but on others you hear all sorts of stuff.
Here's a funny story... I recorded a video course once, and even with a dynamic mic, RDX, etc. a crow was going BERSERK outside of my window, like you would think it was having a fight to the death with a pterodactyl.
Since the video came out pretty nice, I decided to keep it in as a joke since it didn't last too long, and during a spot where it was super loud I decided to throw up a 1 second picture of a crow.
Since the course has come out, I've had about 20 people e-mail me asking me why I showed a crow picture while talking about Docker. Turns out, they couldn't hear it even after I mentioned why I did it and requested to them to play it back a few times in a loop at max volume. Some headphones are just mechanically limited to not emit certain frequencies. Sadly, these are common frequencies in voice, instruments and random background noises that humans can hear.
A pair of MDRV6s can go a long ways. It's no wonder they are used in almost every recording studio.
