White noise is commonly used in the production of electronic music, usually either directly or as an input for a filter to create other types of noise signal. It is used extensively in audio synthesis, typically to recreate percussive instruments such as cymbals or snare drums which have high noise content in their frequency domain. [8]
The control for sample rate reduction (a.k.a. "downsampling" or "averaging") is sometimes shown in Hz for a new sample rate, or as a reduction factor. Sample rate reduction is sometimes shown instead as the number of consecutive samples to average together to create a new sample. A value of 20 reduces the sample rate to 1/20 of its original rate.
A recording is made with the low frequencies reduced and the high frequencies boosted, and on playback, the opposite occurs. The net result is a flat frequency response, but with attenuation of high-frequency noise such as hiss and clicks that arise from the recording medium. Reducing the low frequencies also limits the excursions the cutter ...
An exciter (also called a harmonic exciter or aural exciter) is an audio signal processing technique used to enhance a signal by dynamic equalization, phase manipulation, harmonic synthesis of (usually) high frequency signals, and through the addition of subtle harmonic distortion. Dynamic equalization involves variation of the equalizer ...
Audio noise measurement is a process carried out to assess the quality of audio equipment, such as the kind used in recording studios, broadcast engineering, and in-home high fidelity. In audio equipment noise is a low-level hiss or buzz that intrudes on audio output.
Treble describes tones of high frequency or high pitch, ranging from 6 kHz to 20 kHz, [1] comprising the higher end of the human hearing range. In music, this corresponds to high notes. The treble clef is often used to notate such notes. [2] Treble sound is the counterpart to bass sound.
Noise that has a frequency spectrum of predominantly zero power level over all frequencies except for a few narrow bands or spikes. Note: An example of black noise in a facsimile transmission system is the spectrum that might be obtained when scanning a black area in which there are a few random white spots. Thus, in the time domain, a few ...
Tape hiss is the high frequency noise present on analogue magnetic tape recordings caused by the size of the magnetic particles used to make the tape. Effectively it is the noise floor of the recording medium. It can be reduced by the use of finer magnetic particles or by increasing the tape speed or the track width used by the recorder.
