Microphone IN to equalizer on Raspberry

[pascalbythree]

Does anybody know if the UOS package can be installed on a Raspberry with Lazarus on it? To use the microphone input jack to visualize a equalizer effect on the HDMI plug?

and do you know appropriate version number/numbers?

Or does anybody have example code? Greets, W.

On ubuntu, also fine, then i can port it later.

Is the UOS package going to do the job?

Hello and welcome to uos forum.

Yes, uos works on Raspberry.
There are also compiled libraries provided for this.

You may try Eschecs that uses uos on Rpi:

You may try also StrumPract that uses uos on Rpi, it has recording feature:

Please take a look at all the examples in /uos/examples/.
There are *.lpi (Lazarus project) included.
Just open a project with Lazarus, compile it and run it.

For recording take a look at SimpleRecorder.lpi

About recording from HDMI, I never test it.
But audio works, for sure, with HDMI on Rpi.
