What microphone are you using for Linux?

Get an audio interface. Then you can use any microphone.

I use a Shure SM58 for voice and a Shure SM137 for instruments with a Behringer UMC204HD.

I use a Røde NT-2A. What do you mean by "enhancing your voice?" You want a compressor or EQ?

I supposed both; Pulse Effects looks pretty good but was wondering if anyone is using something different!
- I'd recommend against using pipewire over pulseaudio, and in turn eassyeffects rather than pulseeffects. Pipewire is a much cleaner implementation, way less buggy, has a wider support. As far as I'm aware pretty much every major distro ha smigrated to pipewire aleady.
- I personally run my mic into a DAW and process it with effects there. It's what DAWs are designed to do. I use a DAW output as an audio input for applications. It works great.

Microphones are usually just an analog XLR connector. Good news is most audio interfaces work well in linux because they use standard drivers.

Also suggest the advice of getting an external audio interface. That wy, no drivers shenanigans, as it should be. For me, an Audio-Technica AT2020 XLR works great. Been using some cheap Tonor ones before too.

I use a Audio Technica AT2040 with a Focusrite Scarlett 8i6 audio interface.

Not sure about studio quality, but for video conferencing and doing some Twitch streams, I've being using a Blue Yeti Nano USB microphone for a few years (since COVID) with no issues on Linux.

I use a blue snowball. Dead simple and sounds awesome

I can recommend NOT getting a Focusrite Scarlett 2i2 3rd gen. It does not play well with Linux. It still can work but has issues.

What problem are you having? Ive been using the 2nd gen for years, and didn't notice any problems, except more xruns than I think ought to happen. But it's hard to know what to blame for xruns.
- AFAIK the problems are exclusive to the 3rd gen line.
  
  The biggest thing was sometimes all output coming out as a distorted clipping mess, with nothing fixing it but a reboot. It was random and I can't tell why it happens. Other than that it's a lot of more minor stuff like the configuration software being Windows exclusive.
I'm just curious, what type of issues are you running into with it? I purchased one a short time ago for recording guitar practice sessions for future reference. I haven't used it an enormous amount yet, and I'd like to prepare myself if there's use cases that don't work on Linux.

I'm running Ubuntu Studio, and using a microphone or DI depending on the situation.

Shure SM7B with a dbx 286s preamp going out to a Focusrite Scarlett Solo USB Audio Interface.

A cheap XLR one; Behringer C2 IIRC.

Mic isn't as important as the interface though.
I can highly recommend the MOTU M2 for that. The noise floor is very very low and it's not nearly as expensive as interfaces with comparable performance.

It can also serve as a very good DAC/AMP for almost all high-end headphones. It'd only struggle with extremely inefficient headphones and for those you can always get another AMP and connect that to the interface; using it as a DAC.

MAONO AU-PM421. Works otb no muss no fuss.

Same experience with the AU-PM422 I bought in November of 2020

Works perfectly fine for Discord and OBS

I have a Zoom, it appears as a USB audio input device, never gave me any issues.

Blue Yeti.

Not a street or professional musician, but I wanted something that had great out of the box sound and stereo recording without brealong the budget. I got it on sale.

I don't know the quality now that Logitech aquired them though. With tons of companies, Logitech drives the quality into hell for profit margins.

My Behringer UMC22 interface works perfectly on Linux, including with pipewire. I use it with a Rode NTG-1 shotgun mic, and it also drives my studio monitors.

My Samson Q2U also works great if you're looking for a cheap all-in-one option.

HyperX Quad Cast. Since it's USB, it just works. Sound quality is very good for the price, but you can get better ones of course.

Definitely not a studio quality, but I use Sudotack ST-800 along with noise-suppression-for-voice to get rid of static, key presses, etc.
The price to quality ratio is amazing (obviously the boom arm that comes with it is trash, but again, fine for the price).

Shure SM58 going through an Audient ID4 audio interface. Pretty plug and play.

I use a Zoom H5 as an audio interface. It comes with a stereo Microphone that is really good quality and has two XLR connectors for any mic. No issues with Linux as far as drivers etc is concerned + it doubles as a portable recorder.

I use a Rode NT1 with a Focusrite Scarlett 4i4 3rd (!) gen. It's not quite "just works", you need to set up parameters for the USB sound kernel module to get the Scarlett working. Otherwise it "just works".
Be careful with Focusrite products in general and read the Linux kernel project's instructions very carefully on supported products, in case you're interested in such a device (e.g. it's common that 3rd gen works, 2nd or earlier doesn't).

I use a fifine microphone which mostly works ok. I used to use NoiseTorch when I had a keyboard with clickies but it was more trouble than it was worth (probably zoom linux client's fault not NoiseTorch though).

Rote NT 1 A with an yamaha interface (Ag06)

It's an AKG C214 plugged into a SSL2+, works out of the box with the appropriate kernel drivers. Headphone is a Beyerdynamic DT 770 Pro, also plugged into the SSL2+.

Wave 1. The software does not work because it is made for some other platform, but the hardware is good and does not have any software locked features (very basic mic). The hardware mute key does not unmute the mic though, not sure what's up with that...
