Technically distortion is ANY deviation in the shape of an audio waveform between two points in a signal path. Given that understanding, just about any audio process (equalization, compression) are all forms of distortion.
A melted crayon, a deflated balloon, a CD or DVD with scratches that no longer plays correctly — these things have all been affected by distortion. Other examples of distortion are things like your reflection in a broken mirror or the sound of your voice underwater.
Harmonic distortion may be measured by looking at the output spectrum on a spectrum analyzer and observing the values of the second, third, fourth, etc., harmonics with respect to the amplitude of the fundamental signal. The value is usually expressed as a ratio in %, ppm, dB, or dBc.
A distortion is a change, twist, or exaggeration that makes something appear different from the way it really is. You can distort an image, a thought, or even an idea. To say that I never take out the garbage is a distortion of the facts.
There are four main types of distortion that come from map projections: distance, direction, shape and area.
Two common types of distortion. In barrel distortion (left), magnification decreases with distance from the centre of the image; in pincushion distortion (right), magnification increases with distance.
How much THD is acceptable? As long as THD is less than one percent, most listeners will not hear any distortion. Some musicians and audiophiles, however, may notice that level of distortion.
Size Distortion Refers mispresentation of actual size of the structure as recorded on the film. Another term for size distortion is magnification.
Note that the resulting value may exceed one. According to the standard, h can generally be limited to 50. This equation produces a single value indicating the distortion of a voltage or a current flowing at a given point in a distribution system. Harmonic distortion is generally expressed as a percentage.
There are five basic distortions of this kind: (1) animation; (2) fast motion; (3) slow motion; (4) reverse motion; and (5) freeze frames.
In the art world, a distortion is any change made by an artist to the size, shape or visual character of a form in order to express an idea, convey a feeling, or enhance visual impact.
In audio systems, the most noticeable types of distortion are amplitude, frequency, and intermodulation. In video systems, appreciable distortion of any kind may be observed as a degradation of the reproduced image. Noise added to a signal, either purposely or inadvertently, is sometimes referred to as distortion.
Some common synonyms of distort are contort, deform, and warp. While all these words mean "to mar or spoil by or as if by twisting," distort and contort both imply a wrenching from the natural or normal, but contort suggests a more involved twisting and a more grotesque and painful result.
The cause of distortion is the overload of amplifying a signal. A loudspeaker or a microphone has a transducer that converts energy into another form of energy. In this case, it transforms electrical signals into mechanical movements to create sound.
Distortion occurs when writers twist an idea or thing. It is exaggerated or altered in a way that makes it appear different from reality. This might be done to present that thing in a negative light or to simply rework it in a new way.
Image distortion is when the straight lines of an image appear to be deformed or curved unnaturally, creating different distortion types, including barrel, pincushion, and waveform. Distortion is often the result of the lens's geometrics and can significantly disrupt the image's quality.
An undesirable change in the shape or dimensions of a material. In labelling, the face material can be distorted by a number of factors including changes in the environment, or by being stretched or compressed during manufacturing, printing, or final use.
As used here, distortion will refer to a condition in which the shape of a component has changed without loss of material. Deformation will refer to the process that results in the distortion.
DS pedals were the distorted sound used throughout Kurt's career, but he did replace his DS-1 with the DS-2, which he used with the exact same parameters as his DS-1. Both pedals are similarly priced, so if you want “Bleach” and “Nevermind” distortion then use the DS-1. For “In Utero” and “MTV Unplugged”, use the DS-2.
Kurt started off with the BOSS DS-1 (link to Amazon for price and details), which is one of the most popular distortion pedals of all time. In the albums Bleach and Nevermind, most of the distortion you hear is from a DS-1. At some point, Kurt switched from the DS-1 to the BOSS DS-2.
He was also known for his use of the BOSS DS-1 distortion pedal, which he used on a number of Pink Floyd's most iconic tracks.
Class C Power Amplifier
Lesser conduction angle implies greater distortion and so this class of amplifiers is not suited for audio amplification. They are used in high-frequency oscillators and amplification of Radio Frequency signals.
Distortions. The only 'projection' which has all features with no distortion is a globe. 1° x 1° latitude and longitude is almost a square, while the same 'block' near the poles is almost a triangle.
Distortion refers to the altering or deformation of an audio signal's original waveform. Technically, any kind of audio processing (EQ, compression, time-based effects, etc.) alters an audio signal, but in audio production, the term is used to describe either intentional or undesired sonic destruction.
