// Musical Note to Frequencies and Wavelengths
I wanted to stop looking up “what’s A2 in Hz again” every time a synth only takes a frequency, not a note name. Pick a note off a full keyboard, get the Hz, the wavelength, the MIDI number, and an envelope timing table in six different ratios.
I'd love to tell you more.
// BPM Calculator
I kept doing the same maths by hand. BPM to milliseconds, milliseconds to Hz, for every delay, every reverb tail, every envelope stage. This does it instead.
