Ride the Wave
The number of wave cycles per second, perceived as pitch. One cycle includes both compression and rarefaction.
What is Frequency?
This auditory illusion creates the perception that a sound is coming from the center of two speakers, even though it’s just identical signals played from both speakers.
What is Phantom Center?
Short for “binary digit” this unit of information stores amplitude information. Most commonly found in music in values of 16, 24 and 32.
What are Bits?
The high-pressure point in a sound wave, occurring just before it returns to compression.
What is Rarefaction?
The brain uses this difference in the arrival time of a sound between the left and right ear to locate the direction of a sound source.
Interaural Time Difference
A theory that dictates that the sample rate must be at least 2 times as much as the highest frequency humans can hear.
What is the Nyquist Theorem?
Frequencies that are whole-number multiples of a fundamental tone. They’re present even if not always heard clearly.
What are Harmonics?
These curves, also called Fletcher-Munson curves, show how our perception of loudness changes across different frequencies at the same volume.
What is an Equal Loudness Contour?
The process of adding noise to a signal in order to reduce distortion that can be caused by sample rate issues.
What is Dither?
A sound effect where certain frequencies are boosted or cut due to interference from the sound interacting with itself.
What is Comb Filtering?
This phenomenon causes a sound’s pitch to seem higher as it approaches and lower as it moves away, due to changes in frequency.
What is The Doppler effect?
A distortion that occurs when the sampling rate for an audio signal is insufficient.
What is Aliasing?
In a standing wave, the point of low pressure and high velocity where the wave amplitude is zero.
What are nodes?
This illusion shows how visual information from lip movements can change how a sound is heard, blending sight and sound in speech perception.
What is The McGurk Effect?
Increasing your sample rate to give yourself more resolution is referred to as this.
What is Oversampling?
