CosSignal

Creates a cosine signal with the specified frequency, amplitude, and phase offset. Returns a Sinusoid object that can be converted to a Wave for visualization and audio playback.

Definition

function CosSignal(
  freq: number = 440,    // Frequency in Hz
  amp: number = 1.0,     // Amplitude
  offset: number = 0     // Phase offset in radians
): Sinusoid {
  return new Sinusoid(freq, amp, offset, Math.cos);
}

Parameters

• freq - Frequency in Hertz (default: 440 Hz, the A4 note)
• amp - Amplitude of the signal (default: 1.0)
• offset - Phase offset in radians (default: 0)
