i am new to audio and all this stuff.
I built a sample player using PWM audio output and added some buttons to trigger the samples.
Now, the quality of the output signal is not good - as expected and i would like to add a proper line signal. Whats the best way to go for it?
(I am a bit confused about all the different techniques - DDS, PWM, DAC, ....)
Pls. point me in the right direction. Thank you in advance.
