I will probably switch to using a micro, but getting something working, without one, should help me with writing the code.
I record concerts, and recently switched from recording into a laptop to a multi channel recorder. While I have used worse, the deck's meter is lacking, compared to the software one I am used to. One reason for building this is to get more resolution, the only markings are at -18dB (?) and 0dB. Also, there is no peak hold, so unless I am looking at it, when a spike happens, I do not know how close it came to clipping. In addition, I also want to add a clip indicator,
