Creating an 8-channel, 16-bit audio recorder with ESP32 -- possible?
I use klm8g1getf. It’s 8GB and about $5 from LCSC, easyEDA has the footprint and symbol. I run mine at 52mhz, 4-line mode. I’m able to playback 20 stereo wavs at once @44.1k 16bit. Writing is a lot slower but 8 should be possible. I wrote my own flat file system to prioritize speed, all the standard file systems will slow you down a lot, as far as I could find, sequential reads and writes are much faster, and most file systems don’t do that. https://github.com/marchingband/wvr/blob/main/src/emmc.c

is it possible to port this code to Arduino ide?
https://github.com/marchingband/wvr/blob/main/src/boot.cpp This uses eMMC which is very similar to SD.

Can someone help me make an HTTPS request with an ESP32/How should I do this project?
Look at the secure examples for HTTPClient.

Where do i download the "driver/i2s.h" arduino library for ESP32
I have a sketch that needs that library & i'm not finding a zip file for that library. Expressiff has a github page with this https://github.com/espressif/arduino-esp32/blob/master/tools/sdk/esp32/include/driver/include/driver/i2s.h but I believe I need a lot more than just a .h file
My bad. I think what you mate be after is here

Is there a specific place I can go to when I want to read up on the standard esp32 programming functions?
Meanwhile the espressif32 examples include it - https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Time/SimpleTime

ESP32-C6 Reality Check
Don't expect Arduino support anytime soon. Arduino usually lags ESP-IDF releases by quite a bit. The latest Arduino core release, 2.0.6, is still based on ESP-IDF 4.4.3; moving to 5.x might be a larger undertaking than usual, not sure. I was totally wrong about when the C6 would be released; I might be totally wrong about this, too, but I wouldn't expect Arduino support for a few months.

Choosing a protocol for communication between multiple microcontrollers
As far as I can see, apparently I2C Slave support was added to the ESP32 Arduino Framework.

ESP32-CAM connection without the USB device
Once it's connected you use whatever programming tool you're building with. The Arduino IDE will work if you install ESP32 support. There'll be an option to upload firmware. I use PlatformIO from the command line; it has options to upload when you build firmware. Fundamentally these use esptool.py to flash the firmware to the board (it can also erase the board's flash storage, read it back, and do a few other things). You probably don't want to use it directly unless you absolutely have to; whatever build system you use should be easier to deal with.
- how do emulate a keyboard over usb? wherever I look I only see libraries and tutorials on how to use the eps32 as a Bluetooth keyboard not a wired one
