I am a hobbyist. Doing some experiments with sound quality. I'll pin point my problem and requirements.
Problem statement :I want to play audio files ( recorded in human voice, not music files, just some plain human speech files)
I have tried : a project with an Arduino microcontroller and MicroSD card but audio quality was not at all good from the link below https://www.instructables.com/id/Audio-Player-Using-Arduino-With-Micro-SD-Card/ https://circuitdigest.com/microcontroller-projects/arduino-audio-music-player It just used an arduino UNO board, microSD using SPI, a speaker and an LM386 Audio Amplifier.
I read about the details and got to know that I need a DAC for better quality (as PWM cannot serve the purpose), and a speaker also. But there are a number of things available and I dont understand which one to buy and start a project.
Can you share the details of some micro-controller board with a DAC which suffice my purpose, memory to store audio files (or I can use a microSD card device), and a speaker project which I can follow and make one. I am looking for a board based solution, after getting some results, I can go for separate micro-controller and DAC.
Thanks in advance.
