0 followers · 2 posts · Server hachyderm.ioTrying to work out a #language for #audio synthesis. The thing about audio is there are many dimensions to be varied. There is a lot to like about #LISP ...and it sure is easy to parse. And I know #nyquist is a LISP derivative but that's not right answer. LISP w/o brackets?
It's a winter project because it can be worked on inside. The #snow was flying today and the walk back and forth to the garage is becoming unpleasant.

I again saw a video today claiming that the quality of a digital signal degrades as you approach the Nyquist frequency (half of the sampling frequency). No. That's just not true. A band limited signal, containing information of to a frequency f, can be captured *exactly* by sampling it at any frequency larger than 2f. If you sample a band-limited signal according to this limit and then pass it through a digital to analogue converter you get *exactly the same thing* as you started with. Even if it contains data at 22 kHz and you sample it at 44.1 kHz. (But you really want it to contain nothing above 22.05 kHz or it will be aliased and you will definitely lose data).
