My favorite “cheap” ear plugs are Dubs. They’re comfortable, and they reduce the decibel level without reducing the quality of what you hear. https://getdubs.com. Source: over 1 year ago

They could be dubs. Back when I was regularly attending concerts I had these low-pass earplugs that are designed to reduce the hearing damage from stadium-grade speakers without impacting the sound quality (too much). Source: over 1 year ago

Https://getdubs.com/ Link is for what I have but doesn't look they are around anymore. I've had them for a while. I love those ones, but they are also the only I've ever tried so I won't claim any expertise. Source: almost 2 years ago

These are the DUBS I mentioned previously. They're pretty much invisible. I bought them many years ago from Amazon but today I get zero from the search results. So better order from their own website. Source: about 2 years ago

Mine were a gift from another musician I play with, so he got me pink ones. They're sold out on Amazon, and the website https://getdubs.com/ directs you to Amazon when you click on "shop now." There are lots of options, https://www.musicradar.com/news/best-earplugs-for-musicians has some popular ones. I know earasers is on that list and a lot of people like those.

For transcripts, I use Descript. Descript is able to identify all four of our panel members, and I usually spend an hour or so cleaning it up and setting the transcript into a video for YouTube. Source: about 1 year ago

I don't understand exactly what you are trying to do, but I'm pretty sure Descript can do what you want. Source: over 1 year ago

I tried to use descript.com but found out that they didn't have a download for Linux and that their online version doesn't allow you to edit your transcript. Source: over 1 year ago
