There’s little direct benefit to me when I go out of my way to help someone. But I feel better when I do.
My good feelings are a secondary benefit.
In the same manner, we can find secondary benefits in such audio-related activities as upsampling.
Upsampling provides no more information than what already was there, yet it can often sound better. That’s because the secondary benefit of upsampling is engaging with a different and better-sounding filter inside the DAC.
Sometimes we’re taking primary actions to enjoy secondary benefits.
It helps to understand why.
