An unwanted changing of the audio signal that is caused by a number of factors. One thing that causes distortion is the clipping of the positive or negative excursions of the signal because the electronics cannot handle that strong of a signal. Guitar amplifiers sometimes have boxes that produce this kind of distortion deliberately.
(what has occurred over time to all of energy, which is to say much of the original intent of various energies have been twisted, altered, changed in ways to keep the truth from emerging)
Failure to reproduce accurately the characteristics of an original signal's amplitude, phase, delay, etc.
Distortion is the 'rough' sound that's created when something regarding your speakers isn't working as it should. Usually it occurs when excessively loud playback causes speaker panels to reverberate and diminish the clarity of sound. This can be remedied usually just by turning down the sound to a more acceptable level, or by ensuring your speakers aren't underpowered by adding an amplifier. Ensuring your speakers are amplified correctly means that you don't need to turn the volume up as high to get a good sensitivity rating (i.e. how many watts of power it takes to power a suitable amount of output).
the lack of proper proportion; directions, shapes, distances, and sizes of areas may be shown inaccurately.
The result of changing the shape of a figure from its original form. In the process of map projection the shape, distance, area and angles of features on the curved surface of the Earth are stretched or compressed in order to retain their positional accuracy on a flat map.

is caused by too loud a signal for the audio device to handle. Overloading digital equipment produces harsh noise while in contrast overloading analogue equipment (ie. reel-to-reel tape recorder) sometimes produces a warm compressed sound rich in harmonics. Transient distortion occurs when an audio device is unable to cope with sudden changes in SPL. This can result in a crackly muted pop.

Any change to the transmitted signal. Distortion can be caused by crosstalk, delay, attenuation, or other factors.

Nonlinear and unwanted changes in an audio signal.
Occurs when a sound waveform is not produced accurately, and results in poor sonic performance.
Changes in a signal that involve the addition of spurious tones at frequencies not present in the original sound. In harmonic 'distortion' the spurious tones are at integral multiples of the original frequency. In 'intermodulation' distortion, discordant tones appear at the sums and differences of two original frequencies.
Any change in the waveform or harmonic content of an original signal as it passes through a device. The result is nonlinearity within the device.

any undesired deviation of an image from proportionality.
Any measurable difference, other than in amplitude, between an input signal and an output signal.
when extra gain and distortion cannot be achieved by an amplifier, traditionally a distortion pedal (a fuzz-box/overdriver) is used. A clean signal is plugged in, and a distorted, sustaining sound is produced. The amount and type of distortion can be controlled on the effects unit. Some units include value based pre-amps to give good tone and dynamics coupled with genuine value overdrive. Digitally produced distortion, while very common, does not usually have the warmth of analogue valve based distortion and is often thought to be too harsh for the tastes of most guitarists.
An intentional desired, or unintentional unwanted, change in the audio waveform, causing a raspy or edgy sound quality.
Also referred to as clipping, distortion is a change in an audio signal resulting in the appearance of frequencies at the output that were not present in the original waveform. Distortion is commonly caused by applying a signal that is too powerful for an amp, speaker, or other electronic device to adequately handle. It is commonly employed as a means of creating sustain.
To change or deform something from its normal shape and to it make less realistic.
When an audio signal has been changed by the nonlinear behavior of the microphones, electronics, and loudspeakers. The nonlinearities, whether acoustical, mechanical or electrical, change the audio signals which are passed through them. See: Linear Distortion, Non-Linear Distortion.

When an audio file sounds different than it normally should it is said to be distorted. Distortion is often caused by clipping and can often produce audio that sounds overly rough or harsh.
1.) Sound that is modified or changed in some way. Measured as a percentage of the whole signal. 2.) Any change in the waveform or harmonic content of an original signal as it passes through a device. When a signal flowing thru a circuit is compared at two different points, any change except for magnitude is distortion.

Any deviation from the normal sine wave for an AC quantity. Alternating waveforms with a square or rectangular waveshape can be said to carry some amount of distortion. Typically, a good AC supply waveform will carry 5% THD (total harmonic distortion) content or less. See harmonics, total harmonic distortion.

Anything that alters the musical signal. There are many forms of distortion, some of which are more audible than others. Distortion specs are often given for electronic equipment which are quite meaningless. As in all specifications, unless you have a thorough understanding of the whole situation, you will not be able to make conclusions about the sonic consequences.

This is a measurement of the deviation from the original signal to the reproduced signal. Distortion is a harsh sounding artifact that alters, in a negative way, the signal.

Any unwanted change between an input signal and output signal.
any unwanted change that occurs in an audio signal
The modification of the wave form or shape of a signal caused by an outside interference or by imperfections of the transmission system. Most forms of distortion are the result of the varying responses of the transmission system to the different frequency components of the transmission signal.
A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation. Distortion is usually unwanted. In some fields, distortion is desirable, such as electric guitar (where distortion is often induced purposely with the amplifier to achieve the electric guitar's desired, distinctive, aggressive sound).
