proximity effect has a wikipedia page:
https://en.wikipedia.org/wiki/Proximity_effect_(audio)
Thank you, schrm. I can't say I understand all of that, but I get the general idea.
(that's more or less the same with me :-) )
While deep he-man thundering bass might be effective for "power voice-over" use, it's not appropriate for Librivox, IMHO. Most of the information in speech is between 300Hz and 3000Hz (the so-called "telephone frequencies"). I have a 100Hz high-pass filter on my mic, which I leave switched on.

I mention this because you generally do want to get as close to the mic as possible to reduce the relative intensity of room echo/reverb (unless you have a really well treated sound booth), but getting really close (like a couple of inches away) probably results in booming bass unless you add some kind of filter (in the mic or in post).

I read the Wiki article. I wasn't greatly impressed with it - it didn't really explain why the proximity effect occurs.

well, you can edit it to rise the quality of the article?

in the german version, there are strict rules for editing. but i am not able to really compare the informations between the two versions..
i think you can use google translate to check it, though:

I think it could do with a new section on mobile phones, Ipads,... not that I know anything about these. :lol:

Also, I think that the zoom H2 recorder is not produced any longer. :cry:
I believe the H2n is still produced and sold.

Zoom just announced the F2 yesterday. At $200 with an included lavalier microphone and Bluetooth control, it might be a good introductory option. It’s intended purpose is as an alternative to a wireless lav microphone for video, but it might work acceptably for Librivox purposes.
I purchased an F2 for doing outdoor recordings for my Youtube channel. It'll work fine for that, though I don't think it'll last long because it's pretty flimsy. The quality of the included Lav mic is questionable - I find my old Giant Squid preferable. The lav mics are not really up to Librivox standards IMHO, I have been using my Shure SM58 exclusively. Prior to buying the Shure mic I used my H2 and was very happy with the result.

The main benefit of the F2 is 32 bit float, which is way overkill for Librivox recordings.

FWIW.

More USB mics are coming out all the time at various price points.

Here's a shoot out with samples from Sweetwater:

And here's some recent ones on YouTube:

The following video, which is a few years old, shows how good USB microphones in a treated space can sound:
