My Google-fu is failing me. I bought a little #MAX98357 breakout board and wired it up to an #ESP32, it works but it sounds a bit quiet and naff.
Can anyone point me where I'd learn more about speakers, and what makes them sound nice in the context of "I want to build a small box which streams internet radio which doesn't sound quiet and naff". Youtube or blog posts don't mind.
The #PCM5102 also arrived and this one is even worse than #MAX98357. At least the 98357 accurately describes itself as a DAC + Class D amp. The 5102 just says it is a DAC but is also a Class D amp.
I guess the "generate waveforms" part of this project is on hold until next week. Instead, I can work on software I need to hook up all the bits.
OK, the #max98357 is working and it's if anything even more useless for my purpose than I thought.
I was looking for a #DAC and got a DAC, but with a Class D #amp on the end of it. After I placed the order, I learned "Class D amp" means "this signal is only useful going directly to a speaker".
I'm just going to chuck these in a bin and never use them for anything again. Oooh, I'll play with the wifi/bluetooth on the #esp32 board while I wait for my "programmable waveform generators" to arrive.
