"Also tested it with a signal generator using a fixed frequency and still got the anomalies. This wave should be uniform." @rickyelqasem Do you recall what fixed frequency you were...

If that's the case, then I'm thinking you're getting dropped samples. The best way to work around this would be to increase the buffer size as @stripwax mentioned, as well...

If you're getting sample drops at low sample rates, something is probably wrong somewhere. Not sure how to go about addressing this without a scope though... I'll see what I...

@stripwax Wow lots of changes, nice stuff! Not many people that understand timers and interrupts to this degree, and even having written the code it will take me some time...

I’m goin to guess that your shield uses pin 10 for the SD card so it’s likely you can’t use stereo mode with that shield > On Sep 6, 2022,...

The speaker pins are specific to the device, On the Mega, you can use 5-2,6-7,11-12,46-45 but on Uno, Nano,etc devices, you can only use pins 9 and 10.

No feature built in no. The best option would probably to increase the level of the input when recording. Alternately you could change the line https://github.com/TMRh20/TMRpcm/blob/master/TMRpcm.cpp#L658 to `buffer[whichBuff][buffCount] = ADCH

Not really, the only thing I can think of would be if you match up the sample rate of the recording with the sample rate of the input for the...

I've taken a quick look at this, and honestly I don't know why it stops working, but two workarounds are: 1. Disable Auto-Ack - It should work fine without auto-ack...

I'm not sure what effect that would have?
