Music
Envelope Time Calculator
Convert an ADSR envelope stage duration from milliseconds into the equivalent number of audio samples at a given sample rate. Essential when programming synthesizers or audio plugins that specify envelope times in samples rather than milliseconds.

Music
Filter Cutoff Calculator
Convert a MIDI note number and octave offset into its corresponding filter cutoff frequency in Hz. Useful for synth programming and sound design when you want to tune a filter precisely to a musical pitch or harmonic relationship.
