Module "gen/sweep"

Const sweep

• sweep(start: number, end: number, steps: number, rate?: undefined | number, clamp?: boolean): IGen<number>

• Similar to curve, but with added accumulation (via addG). Systax sugar for addg(curve(...)) and intended for creating oscillator frequency sweeps. By default, the sweep speed is clamped at the given end value.

  example

  // render 2 sec osc sweep from 100 - 10000Hz
  // FS = 44100
  osc(
    sin,
    // freq & phase gen
    sweep(100 / FS, 10000 / FS, 2 * FS, 0.1),
    // amplitude gen / envelope
    adsr(0.5 * FS, 1.5 * FS, 0)
  ).take(2 * fs)
  // [...]

  Parameters

  • start: number

  • end: number

  • steps: number

  • Optional rate: undefined | number

  • Default value clamp: boolean = true

    true, if clamp at end value

  Returns IGen<number>
