Brownian noise ls known as Brown noise or red noise, is the kind of signal noise produced by Brownian motion hence its alternative name of random walk noise. The term "Brown noise" comes not from the color, but after Robert Brown, the discoverer of Brownian motion.

Pink noise is a signal or process with a frequency spectrum such that the power spectral density is inversely proportional to the frequency. In pink noise, each octave carries an equal amount of noise power. The name arises from being intermediate between white noise (1/ƒ0) and red noise (1/ƒ2), more commonly known as Brownian noise.

Hi, I am trying to record vocals and have been for years. The problem is, there is digital noise or hum while no sound is going into the mic. I have turned off the mic and there is still the same hum. I have unplugged the mic, still same noise.

Here is an example of a wide white noise effect used in a track which seems to have no phase cancellation whatsoever. If you mono the sample the white noise shows zero phasing and sounds exactly the same in mono. Any idea's on how the hell this is done? All my attempts and techniques have left me with big wide sounds but with slight phasing.

Refers to the sensitivity that a microphone exhibits to movement, the actual holding of the microphone and shock. A microphone's ability to lower handling noise is a direct result of the construction of the microphone, and to that end, some manufactures employ internal shock mounts for the capsules to eliminate as much handling noise as possible.

Hi,

I just wanted to ask you this noise interfering in any kind of recordings. Both Line-In and regular micing...

Please listen to it here;
It's a bass recording but there is this terrible noise there and there.

The amount of self-noise generated by a piece of electrical equipment when it is at rest (no signal passing through.) All such devices generate noise to some extent or another, and engineers are constantly striving to lower this artifact. Measured in decibels.

A range of technique developed for reducing the amount of noise in an audio signal. Dolby NR is an example of a system designed to reduce the amount of tape noise that is inherent in the analog tape medium.

A system developed to compensate for the quantization errors that are introduced into digital audio files when reducing the bit rate of the data, such as when preparing audio for CD duplication. A certain amount of noise is added to the audio data, which helps to smooth the errors. In which part of the audio spectrum this noise resides varies from one developer to another.

A squelch detection technique that monitors noise at the FM demodulator output, at frequencies above the audio range. A high level of noise in this region indicates a weak or unusable RF signal, or some form of interference.
