Comparison chart for Best Microphone For Arduino 
Application: the MAX4466 microphone breakout is suitable for voice converters, audio recording and sampling, and audio response projects using FFT; On the back, there is a small trimmer pot to adjust the gain; You can set the gain from 25x to 125x
Parameters: power supply voltage: +2.4V to +5.5V (can be compatible with STM, Raspberry Pi and other development board motherboards); Power supply rejection ratio: 112dB; Common mode rejection ratio: 126dB; AVOL: 125dB (RL = 100 thousands of ohm meter) rail-to-rail output; Quiescent power supply current: less than 24 microamp; Gain bandwidth: 600kHz
20-20KHz electret microphone soldered on: comes with a 20-20KHz electret microphone soldered on the board for audio-reactive projects; It is recommended to use the FFT driver library, which can take audio input and 'translate' it into frequencies
Easy to use: connect GND to ground, VCC to 2.4-5VDC; For the good performance, use the 'quietest' supply available (this would be the 3.3V supply)
Power supply noise rejection function: the amplifier has good power supply noise rejection
PRODUCT ADVANTAGES: The main chip is LM393. Signal is clean, waveform is good, driving ability is strong.
ADJUSTABLE THRESHOLD: Build in potentiometer can be used to adjust the threshold level.
EASY TO USE, INTUITIVE: When sound intensity exceed a certain threshold, produces low(Digital output 0) signal and light will be off, Otherwise output high(Digital output 1) signal and light will be bright.
EASY TO INSTALL: There is a mounting screw hole, convenient fixed.
WIDELY APPLICATIONS: a variety of platforms including Arduino / AVR / ARM/PIC.
The module has 2 outputs: AO, analog output, real-time output microphone voltage signal; DO, when the sound intensity reaches a certain threshold, it outputs high and low level signals, [threshold-sensitivity can be adjusted by potentiometer]
There are 3mm mounting screw holes, which are powered by a 5v DC power supply.
There is an analog output with a threshold flip level output.
High sensitivity microphone with high sensitivity.
There is a power indicator and the comparator output has an indicator.
MAX4466 microphone breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x.
Add an ear to your project with this well-designed which has excellent power supply noise rejection.
Using is simple: connect GND to ground, VCC to 2.4-5VDC. For the best performance, use the "quietest" supply available.
For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.

1.The MAX9814 is a high-quality microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. The device features a low-noise preamplifier, variable gain amplifier (VGA), output amplifier, microphone-bias-voltage generator and AGC control circuitry.
2.A trilevel digital input programs the output amplifier gain. An external resistive divider controls the AGC threshold and a single capacitor programs the attack/release times.
3.The low-noise preamplifier has a fixed 12dB gain, while the VGA gain automatically adjusts from 20dB to 0dB, depending on the output voltage and the AGC threshold. The output amplifier offers selectable gains of 8dB, 18dB, and 28dB. With no compression, the cascade of the amplifiers results in an overall gain of 40dB, 50dB, or 60dB.
4.The MAX9814 is available in the space-saving, 14-pin TDFN package. This device is specified over the -40°C to +85°C extended temperature range. MAX9814: Simplified Block Diagram MAX9814: Simplified Block Diagram Enlarge+
5.A trilevel digital input programs the ratio of attack-to-release time. The hold time of the AGC is fixed at 30ms. The low-noise microphone-bias-voltage generator can bias most electret microphones.
