MUIC & ACOUTIC – AUDIO IGNAL PROCEING & DP CALCULATOR
Phaser Notch Frequency
A precise tool.
What is the Phaser Notch Frequency & How does it work?
A phaser is an audio effect that creates a sweeping tone between two frequencies, often used to add depth and texture to sounds. The phaser works by splitting the input signal into two identical signals, applying all-pass filters with varying phase shifts to each, and then recombining them.
The notch frequency of a phaser’s all-pass stage is crucial as it determines where in the audio spectrum the phase shift occurs. This notch moves across the frequency spectrum over time, creating the sweeping effect characteristic of phasing.
f_n = frac{text{sample rate}}{2 times N}
f_n = notch frequency, sample rate = audio sample rate in Hz, N = number of poles in the all-pass filter

Frequently Asked Questions
What is the purpose of a phaser in music production?
A phaser creates a sweeping tone between two frequencies to add depth and texture to sounds by splitting, filtering, and recombining audio signals.
How does the notch frequency affect the phaser’s effect?
The notch frequency determines where in the audio spectrum the phase shift occurs. As it moves across the spectrum over time, it creates the sweeping effect characteristic of a phaser.
Can you explain how a phaser works with all-pass filters?
A phaser splits the input signal into two identical signals, applies all-pass filters with varying phase shifts to each, and then recombines them to create the sweeping effect.
What is the role of the notch frequency in a phaser’s all-pass stage?
The notch frequency is crucial as it determines where in the audio spectrum the phase shift occurs, affecting the sweep range and depth of the phaser effect.
How does changing the notch frequency impact the phaser’s sound?
Changing the notch frequency shifts the location of the phase shift across the audio spectrum, altering the sweep pattern and overall texture of the sound.
Is there a specific formula to calculate the notch frequency for a phaser?
While not universally standardized, calculating the notch frequency often involves considering the desired sweep range, signal processing parameters, and the specific requirements of the audio effect.
Can you provide an example of how to use this calculator for a phaser?
To use this calculator, input the relevant parameters such as the sweep rate, depth, and desired frequency range. The calculator will then determine the optimal notch frequency settings for your phaser effect.
