Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
Equalizer effects: Boss GE-7 Equalizer, MXR 10-band EQ Pedal. Peter Frampton's Talk box. Talk box: A talk box directs the sound from an electric guitar or synthesizer into the mouth of a performer using a tube, allowing the sound to be shaped into vowels and consonants with movements of the mouth. The modified sound is then picked up by a ...
The Aphex aural exciter was one of the first exciter effects. The effect was developed in the mid-1970s by Aphex Electronics. The aural exciter adds phase shift and musically related synthesized harmonics to audio signals. The first Aural Exciter units were available in the mid-1970s, exclusively on the rental basis of $30 per minute of ...
Up to EAX 2.0, the technology was based around the effects engine aboard the E-mu 10K1 on Creative Technology's and the Maestro2 on ESS1968 chipset driven sound cards. The hardware accelerated effects engine is an E-mu FX8010 DSP integrated into the Creative Technology's audio chip and was historically used to enhance MIDI output by adding ...
The Pultec EQP-1 Program Equalizer is an audio equalizer produced by Pulse Techniques (Pultec) beginning in 1956 with variants produced until 1981, and put back into production in 2000. The EQP-1 and its variants were widely used in professional recording studios and established as a studio standard.
A monitor engineer and console at an outdoor event. Live sound mixing is the blending of multiple sound sources by an audio engineer using a mixing console or software. Sounds that are mixed include those from instruments and voices which are picked up by microphones (for drum kit, lead vocals and acoustic instruments like piano or saxophone and pickups for instruments such as electric bass ...
Delay effects add a time delay to an audio signal. Blending the delayed audio with the original audio creates an echo-like effect, whereby the original audio is heard followed by the delayed audio. [5] The delayed signal may be treated separately from the input audio - for example, with an equalizer. [34]
Digital room correction may involve minimum phase algorithms, to maintain wavefront coherence over the intended frequency range.. The use of analog filters, such as equalizers, to normalize the frequency response of a playback system has a long history; however, analog filters are very limited in their ability to correct the distortion found in many rooms.
