Microphone Recomendation

Post by bzuiss »

Hello everyone, first time post here. Right now I'm working on a project that involves a MSGEQ7 IC. I would like to implement a microphone to replace the line-in input that I'm currently using. The project is designed to analyze music that is playing and generate LED outputs accordingly.

The problem is that the music volume could vary from loud to very loud, would the "MAX9814 WITH AUTO GAIN CONTROL" be a suitable choice for this application?

The example on the introduction video only mentions "speaking" volumes.

It depends on what aspect of the music you want to convert to a visual display.

The chip you mentioned breaks audio input into frequency bands. The MAX9814 will preserve the relative frequency levels of the input moment by moment, but will flatten out changes in absolute volume over time.

Do you want to replace the equalizer chip entirely, or are you looking for an alternate input source.

I was looking for an alternate input source.

In that case, the automatic gain control won't cause any trouble for you.

The MAX9814 should work.
