	Flanging - Wikipedia, the free encyclopedia
		Flanging is a time-domain based audio effect that occurs when two identical signals are mixed together, but with one signal time-delayed by a small and gradually changing amount, usually smaller than 20 ms (milliseconds).
		This produces a swept 'comb filter' effect: peaks and notches are produced in the resultant frequency spectrum, related to each other in a linear harmonic series.
		The effect can then be accentuated by putting a finger on the flange (that is to say, the rim) of one of the tape reels so that machine is slowed down, slipping out of sync by tiny degrees.

	Audio Glossary - Blaze Audio
		Digital audio is audio that has been converted into a series of ones and zeros that can be understood by a computer.
		An audio effect that distorts sound by applying a short delay and variable modulation of the frequency.
		A method of delivering audio from the internet to your media player that allows you to play the audio as you are downloading it, rather than waiting for the entire file to finish downloading.

	3D audio effect - Wikipedia, the free encyclopedia
		3D audio effects are a group of sound effects that attempt to widen the stereo image produced by two loudspeakers or stereo headphones, or to create the illusion of sound sources placed anywhere in 3 dimensional space, including behind, above or below the listener.
		Effects from QSound Labs have been used on albums from Sting and Madonna in the beginning of the 1990s.
		Using head-related transfer functions and reverberation, the changes of sound on its way from the source (including reflections from walls and floors) to the listener's ear can be simulated.

	Gamasutra - Interactive Music: Avoiding a DirectSound3D Disaster [04.17.98]
		Virtualization localizes a specific channel of audio (such as left rear) to a specific location, as opposed to localizing a specific sound to an exact location (which is what occurs in 3D positional audio).
		This effect is especially useful for PC speakers that are built into the monitor because it makes the sound appear to come from a much wider sound field than the actual speakers, which in this case are very close together.
		Care must be taken never to apply this effect to an audio stream that has already been processed by a 3D positional algorithm, because spatialization alters the phase of the signal and can destroy the 3D positional effect.

	waveffect -- apply user-specified audio effect(s) to a WAV file (m-function)
		This field must contain the handle of the respective audio effect function to be applied to the data (on a chunk-by-chunk basis).
		In the case of multiple effects, the effects are applied one after the other (to each chunk of data) in the same order as implied by the ordering of the structures containing the respective function handles.
		to the i'th effect, etc. Note that the first input argument to the effect function is the array of (audio) data itself, and the second input argument is the respective (augmented) AudioEffect structure, thereby enabling any arbitrary parameter data to be sent to the function.

	Turning Up the Volume with Audio Units
		Audio Units is Apple's audio plug-in technology that allows you to create audio effects and virtual instruments for Apple applications such as GarageBand, Soundtrack, Logic and Final Cut Pro, as well as a multitude of popular third-party applications and systems.
		This is possible because of the way that Core Audio integrates a range of audio functionality directly into the Mac OS X operating system in ways never before possible, enabling unprecedented performance and ease of use in a virtual studio.
		Audio Unit Effect Templates which are available separately from the SDK at the time of this writing.

		Audio effect mixing is traditionally implemented with either expensive hardware or inadequate software.
		These effects can be saved for later use and can be bound to keys on the keyboard to allow quick application of effects in real time.
		Other tasks such as the application of multiple sound effects in real-time, the saving and reuse of user-defined sound effects, and the importing and exporting of multiple audio sources are also done routinely.

	Developing Real-Time Digital Audio Effects for Electric Guitar in an Introductory Digital Signal Processing Class
		Audio effects such as flanging, chorus, phasing, and delay are all used to enhance the electric guitar sound.
		Enhancing the introductory DSP course with real-time guitar audio effects projects had to be done in such a way as to keep the additional "effort burden" described in Section I down to a minimum.
		The flanging effect was originally produced by playing music through two reel-to-reel tape players simultaneously and periodically slowing down one tape by manually pressing the flange of the tape reel.

	Glossary - The Sonic Spot (Site not responding. Last check: 2007-10-09)
		Chorus - an audio effect used to "expand" or "thicken" a sound by playing multiple versions of the input signal with slightly different delays and changes in pitch simulating an ensemble of the input sound.
		Delay - an effect that is used to add depth or space to an audio signal by repeating the input one or more times after a brief pause of a few milliseconds to a few seconds.
		The word sample may refer to either a single moment in a digital audio stream (the smallest piece of data used to represent an audio signal at a given time) or a complete sound or digital audio stream made up of a collection of individual samples.

	Audio effect - Delay
		This effect uses a RAM buffer to store the audio for a certain amount of time, after which it outputs this audio.
		The RAM buffer will not always be just large enough to store the amount of audio set by the current delay time, but will actually be considerably larger sometimes, because many delay effects allow for their delay parameter to automated.
		Some multi-tap delays feature a modulation section that modulates the delay times, which can be used to create chorus effects.

	Audio effects algorithms (Site not responding. Last check: 2007-10-09)
		The reverberation effect can be varied by using different delay times for each comb filter, and also by using different number of comb filters.
		By ping-pong, I am not referring to the ping-pong effect mentioned earlier, but rather to the way in which the samples are processed from the input buffer.
		Another method of pitch shifting is to use the effect of an exhaggerated chorus which leads to an upward, followed by a downward pitch shifting.

	Adding Audio Effects with Premiere 6.5 (Site not responding. Last check: 2007-10-09)
		This alters the phase of the audio at its center frequency and sounds like the Chorus effect but can be a bit "wavy." It has three of Chorus's four controls.
		In this case, Feedback (how much of the delayed audio is added back to the original audio) is very similar to Mix, and Delay Time is self-explanatory (same as Depth in the Chorus effect).
		This is the trickiest effect from the standard Premiere palette.

	The Hutchison Effect - American Antigravity
		One way to visualize this energy is very comparable to ripples on the surface of a pond -- where the ripples meet each other, they will create an isolated "peak" that has more energy than either of the two ripples that contributed to it.
		Experiments - John Hutchison's experiments have been exceeding difficult to replicate due to the extraordinarily complex arrangement of waveforms that is seemlingly required to generate the Hutchison effect.
		The Hutchison effect has been known to cause the spontaneous levitation of a variety of common household and workshop materials.
