problems with esp32

[predomaquilare]

sup guys, i was trying to record some stuff with a old mic module and the esp32 module by itself, with sd card. but im having this problem when i send de record option to serial monitor, as you can see below

im using the sdaudiorecording.ino example, an esp32 regular board and an analog mic
by the way sorry for the bad english :(

There is an example included specifically for the ESP32, but even that doesn't work very well. I don't think recording is really possible on the ESP32 without glitches, so I've kind of abandoned that code and have considered removing it from the library since I can't get it working properly.
