Oversampling: How and Why

[the_bertrum]

Now I just need to start oversample school.

Unless for reasons of interest the only oversampling lesson you need is this:

1. Disable oversampling and listen to a wide range of music for a week or two to get the "base".
   
2. Enable oversampling at the maximum rate of your DAC (to effectively bypass the DAC oversampling) using one of the default recipies.  Listen to  a wide range of music for a week or two to decide if you prefer the sound.
   
3. Repeat 2 with the other default recipies.
   

You will then know if you need oversampling at all (i.e. is SoX on your RPi better then onboard in your DAC), and also probably have found a recipie that someone else worked out as being good.  It would take years of study and experimentation to do better so only go that way if that's what is fun for you.
