What partition scheme have you selected?
Do you need OTA program changes?
I'm sorry but I have no idea what you are asking. If OTA means over the air then none needed. It's a project that once it's done it will stay like that. Maybe change colors here or there within the code but that will be done via usb.

I tried this simple wifi radio that was one of the first projects I tried to verify sound. This also gives error of too much memory. If these libraries get so large that you can't add any actual code then what are we to do?

In the IDE under Tools, change the memory partition scheme to something that will accommodate your program.
Try the one for Huge APP.
Sketch uses 1492452 bytes (47%) of program storage space. Maximum is 3145728 bytes.
Global variables use 64976 bytes (19%) of dynamic memory, leaving 262704 bytes for local variables. Maximum is 327680 bytes.
That worked. At least it compiled. So the partition scheme changes the way the board uses the available memory.
Ok, I got it to compile but, I get no sound. No errors compiling. However, looking at the serial monitor I get some kind of error and reboots. Playing mp3 from sd works great separately. when combined I get that error with reboot. I will attach the code and then the serial output. Notice when the code goes through the pink matched card I get no error because I didn't call for sound.

I have no idea what is going on, but you might get a clue from using the EspExceptionDecoder to analyse the Backtrace.
https://github.com/me-no-dev/EspExceptionDecoder?tab=readme-ov-file
I do not think that the ExceptionDecoder tools works in IDE 2.x.x and you will need to install 1.8.19 to compile and run the sketch to get the error and feed it to the decoder.
Playing mp3 from sd works great separately. when combined I get that error with reboot.
Combined with what?
I'm not very familiar with the esp32 and what you have going on with the audio files. I would suggest that you create a more simple environment perhaps without the NeoPixel and the card reader to see what is going on when you call for sound.
That’s what I meant by separately. I ran a simple play from sd code and it works great. I also ran the code with rfid and neopoxels and it run great. When I combine the sound with the rfid and neopoxels I get that error on the serial output. If you can look at the error I posted you could see that the first and the last get the error but the one in the middle “pink” does not. That is because I did not include the call for sound in that “if” code.
The weird thing is I have a working model from last year that I had not compiled for awhile. When I tried to compile to duplicate is when I started getting all these errors. I have completely erased all arduino files including in local data file and re-installed the older IDE and libraries but still get the compiling error and the memory error we solved earlier. Although I never had that memory problem before. IDK. It’s hard to learn something when they change so fast, especially as a hobby.
Heck, on the original I even have it triggering a different relay and combination of both relays.
Wow, great surprise this afternoon. I just upgraded everything including to the new IDE just released, and everything works! the only issue I had was the memory thig which cattledog had already helped me with. Thanks alot for evreyones help.

It is true that one is specific to Arduino IDE 1.x. However, there is a new one for Arduino IDE 2.x:
