A sound that is not part of the original signal. Distortion can be a modification of the original signal, or generating new signals that result from the interference of a combination of signals (harmonic distortion). Can be characterized as a roughness, fuzziness, harshness, or stridency in the music.
Time Based effects alter the timing of of a signal which can create short or long bursts of sound.
The most popular time based effects are reverb and delay which are very commonly used. Many of the effects that are most noticeable in modern music production are time based. these are acheived by mixing a signal with a delayed copy of itself, unlike dynamics and filter effects which are often used to enhance recorded sound without being obvious to the listener.

Definition - In signal processing, especially electronics, an algorithm or device for removing parts of a signal.
Modulation effects are used to add motion and depth to a sound. They typically delay the incoming signal by a few milliseconds and use an LFO to modulate the delayed signal. The name 'modulation' says exactly what it does which is to 'adjust' or 'adapt'.
Pitch is the quality that allows us to classify a sound as relatively 'high' or 'low.' Pitch is determined by the frequency of sound wave vibrations. However, frequency is a precise scientific unit of measurement; while pitch, although defined by its frequency, also has a subjective component which takes into account the relative placement of the frequency within the context of an established tuning system and in relation to other frequencies.

The specific quality of a sound that makes it a recognizable tone. Pitch defines the location of a tone in relation to others, thus giving it a sense of being high or low.

A definite pitch is a musical sound that has a steady and measurable frequency and can be assigned a hertz number. The sound waves of definite pitches move in a repetitive and evenly-paced pattern with a constant distance between the peaks and valleys of each wave.

dynamics are audio processing techniques that can be used to change the impact, clarity and subjective quality of audio. these techniques include adaptive limiting, compressing, expanding, limiting and gates
One of the first traces of delay was used in the early 1920s
In the late 19th century wallace clement sabine started experements at harvard university to investigate the impact of absorption on the reverberaton time, using a portable wind chest and organ pipes as a sound course
Distortion is used to create various effects in existing audio, usually a "warm" and "dirty" sound. Distortion can be used in live performances using guitar using effects pedals. Distortion is used throughout music both digitally and with a hardware set up.

Distortion can also be used and occur unintentionally
due to equipment set up un correctly, hearing
Music from outside of a club only hearing the
low ends and also bad quality audio that is
played though a Large Sound system.

Types of modulation
.chorus effect
.ensemble
.flanger
.microphaser
.modulation delay
.phaser effect
.ringshifter
.rotor cabinet effect
. scanner vibrato effect
. spreader
. tremelo effect
In the late 1960's delay devices were widely marketed.
Throughout the 70s the delay effect evolved from analog to digital.
-audio filters manipulate a sounds frequency spectrum.
-there are many different types of filter but there are some more common such as, low pass, high shelf, band pass, band reject, low shelf and high pass.
-each filter has controllable parameters
By the 90's all digital mixers and modular digital multi track recorders appeared with track delay which made delay very common.

.All of these modulation effects are closely
related to psychedelic music of the 60's,
an example of this would be classic guitar a pedals
and other similar hardware technology.

. As technology advanced, a lot of the sounds heard were transposed into a software format and expanded into a multitude of different effects.




the most popular of dynamics would be
a compressor which is used in most tracks today
although it is often digital the older analogue models
are often preferred but are expensive.
here is a Teletronix/Urei/Universal Audio LA-2A which is sometimes regarded as the best analogue compressor ever made
Hearing Audio from outside a club
The origin of Distortion was created by mistake by a guitar player who broke his amplifier before a live set, it was originally achieved by forcing too much electricity through a guitars amplifier values.
n a 1966 Journal of the Audio Engineering Society article, William Marlens traces the history of analog pitch and time changing devices, with the earliest patents dating back to the 1920’s. The basic idea of all of the patents was to record the audio signal onto some moving medium (tape, wire, film, etc.), and then use a rotating playback head, where the read heads would be moving at a different rate as the recording head:








Auto-Tune, an electronic pitch management tool, is an audio processor created by Antares Audio Technologies which uses a proprietary device to measure and alter pitch in vocal and instrumental music recording and performances.[2] It was originally intended to disguise or correct off-key inaccuracies, allowing vocal tracks to be perfectly tuned despite originally being slightly off-key. This came to be known as the Cher effect.

.Modulation effects are subject to personal
preference and the genre music being made.

. Effects such as flangers and phaser are popular
within djing and can be used for live sound manipulation to create smooth/creative transitions between tracks.

. LFO's are popular within genres such as drum and bass and dubstep because they can create a sense of
aggression and a perception of pace .

compression and limiting is often used when making drums, it makes most drums sound crisper and levels out the different volumes of audio to make a better overall drum pattern
before
designed by bob moog himself its an independant analogue VCF filter which has with knobs to control filter cutoff, resonance, envelope amount and mix.
The MF-101 has been used by Fatboy Slim and The Crystal Method.
REVERB:
Reverb gives the reflected sound of a hall/room. for example if you dropped a brick in a church you would hear the noise still after the impact.

For example if you wanted your drums to sound like they were in the same room you would bus it to the same reverb to create that effect.

delay could make a noise sound atmospheric or even eerie. Delay can also make the sound more dense as the delay will layer the sound.
