Any recommendations for microphones that are (a) high-quality, (b) cheap (under US$5.00), (c) small (under a cubic centimeter), and (d) with analog output (such as a 1/8-inch plug)?
Note that high-quality and cheap are not contradictory requirements. iPhones and other smartphones have extremely high-quality microphones (and they are tiny) and must certainly cost much less than $5 as a part, but they seem impossible to find. Every off-the-shelf mic under $5 that I've tried has been garbage in terms of sound quality, and even much more expensive ones have not been great.
Good mics certainly exist. Here's a compact analog microphone I own that has fantastic sound quality:
But it's ridiculous that this microphone costs 6x as much as the CHIP and 10x as the RPi Zero. You can't build a product around the CHIP or the RPi if an essential part is that expensive.
Is there a box you can plug an xlr mic into, and have it apply effects like this and output a usable signal? I'd like to move towards a real mic, but setting up filters on each of my work machine, home machine and phone sounds really annoying.
Is this something an rpi would be good for? Is there a writeup somewhere of how to do something similar?
So you want to use an analog microphone with the Raspberry Pi? Why?
As far as I know there are three kinds of microphones:
* The cheap analog ones, can be USB or audio jack. Presumably you want one of these?
* The digital ones, USB. Even some MEMS microphone chips now come integrated with amplifier and ADC. This can be almost as cheap as the preceding option, but can also be high quality; seems like the best option.
* The XLR proffesional microphones. You probably do not need or want this, assuming you will use just one microphone per Pi.
Do you have a recommended mic setup for a Raspberry Pi? Devices like the Echo have multiple mics, etc., to detect voices in otherwise noisy rooms, so if there's something like that for a DIY setup that would be awesome.
Anything with a condenser microphone and a wired headset would do, just please don't use Bluetooth headsets. The Bluetooth device is in HSP mode for duplex audio with worse bitrate than a landline phone.
