croma

• Chroma describes the angle of pitch rotation as it traverses the helix. • Two octave-related pitches will share the same angle in the chroma circle: a relation that is not captured by a linear pitch scale (or even Mel).

Short for "chrominance" or color information, which includes its hue (color) and saturation (shade/brightness). Chroma is not a term most people hear or see very often, but it is not entirely hidden (see caption below).

Chromagram is defined as the whole spectral audio information mapped into one octave. Each octave is divided into 12 bins representing each one semitone. The same strategy based on instantaneous frequency (IF), presented in [10], is adopted in this work to compute the features chroma.

Pitch chroma: The distinctive quality of a specific tone, separating it from the rest of the tones within an octave. It describes perceptual 'differences'/'distances' of pitches within an octave and the perceptual sameness of pitches separated by one or more full octaves.

This technique is also referred to as colour keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific colour-related variants such as green screen or blue screen; chroma keying can be done with backgrounds of any colour that are uniform and distinct, but green and blue backgrounds ...

Chroma: the quality of a color's purity, intensity or saturation. For example: A gray color is a neutral -- an extreme low chroma. Fire-engine red may be a high-chroma red. Brick red may be a middle-chroma red.

Tone height is a (approximate) logarithmic function of frequency. except outside of the musical scale. 3. Tone height is partly replaced by “thinning out” towards highest frequencies.

1,000 cycles per second A hertz is a frequency equal to one cycle per second, and you often see it abbreviated as Hz. A kilohertz (kHz) is 1,000 cycles per second. One of the properties of an MP3 file is the number of audio samples per second, so a rate of 44.1 kHz is an MP3 file with 44,100 samples of audio data each second.

The chromatic scale (or twelve-tone scale) is a set of twelve pitches (more completely, pitch classes) used in tonal music, with notes separated by the interval of a semitone.

Green and blue may be the most common chroma colors but they are not the only options. Technically speaking, any solid color can be used as a background. Red, purple, orange, brown, any solid color at all.

It has often been advanced that pitch is a two-dimensional perceptual attribute, its two dimensions being: (1) tone height, a perceptual quality monotonically related to frequency; and (2) tone chroma, a quality shared by tones forming an octave interval.
