Nice work! That's finally becoming a thing! You forgot to mention some of the important parts, but they're visible in your traces, the kernel is 6.5.0, only one CPU core is seen (maybe freertos continues to run on the second one?) and the device has 8 MB RAM. Of course this is a large device but at least we can get Linux to run into this! It suddenly opens the way to many more portable applications.

Kernel 2.1.7 could fit, without modules, and busybox root filesystem in ~800K, leaving 200K for user files. I had a x86, PowerPC and StrongARM SBCs in the book.

A whole Ubuntu distro seems like a bit too much for an ESP32. For those boards, busybox with a lightweight kernel and specific kernel modules, maybe the RT module and a few others depending on purpose, and whatever other specific software you wanted (since you require Linux) would be better if you need Linux on it. You could easily do all those using Gentoo, if you don't wanna manually put everything together. If you don't specifically need Linux, FreeRTOS is probably a better choice.

@Debloper

10 ай бұрын

For audio, only 2.5 things you need to take care of beforehand, rest can be fixed in post-production. 1. The mic shouldn't have heavily distorted frequency response curve (usually not a concern, even with cheap lavs) 2. The amplitudes should not clip for whichever output level you're working with (mic level 1mVpp or line level 1Vpp) 2.5. The ambient noise level is at least -20dB (better if -40dB) away from the gain of sound that you're trying to capture. Once you've taken care of these things, everything else can be tuned/tweaked in a DAW. I'd recommend davinci resolve's fairlight (free, feature rich, cross-platform, AI denoise, comes with the video editing software itself etc), but there are many good options. How much time and energy you'd wanna spend correcting/improving the audio is upto you (there's literally no ceiling to that). But given that your videos are going to convey information, and they're primarily not about entertainment/aesthetics, you shouldn't have to be too worried about that part. I see that you take feedback very positively, which I highly value as a growth-mindset trait. Hopefully it helps; all the best!
