Your F, defined on line 26 [0], is 3Hz off according to this reference table[1]. 346.23 should be 349.23. Just a typo? All credit to @issa's ear. And yes, while you'd be unlikely to have encountered this bug if you were just telling a good existing synth to play an F, it's cool that you implemented the synth from scratch! Whether it's a good choice depends on the project goals. [0] https://github.com/JNKKKK/pianochord.io/blob/master/src/libs... [1] https://pages.mtu.edu/~suits/notefreqs.html

I implemented the synthesizer from scratch. Honestly I'm not super familair with digital synthesizer theory and for the implementation, mostly I referred to this article https://keithwhor.com/music/ The code of my implementation is at https://github.com/JNKKKK/pianochord.io/blob/master/src/libs... I guess it't not a good choice to implement that part on my own, since there are many good libraries out there, like tone.js. I will probably deprecate my own synthesizer implementation and use tone.js.

The code is open sourced on Github. https://github.com/JNKKKK/pianochord.io
