  Wavetable synthesis - Wikipedia, the free encyclopedia
Upon playback, these wavetables are used for sample "lookup" in the same manner as in a Numerically-controlled oscillator (or a Digitally controlled oscillator) but in wavetable synthesis, the output waveform is not normally static and evolves slowly in time as one wavetable is mixed with another, creating a changing waveform.
A common misdefinition of the term "wavetable synthesis" is that of any one of many sample based playback devices in popular soundcards and sampling keyboards.
The difference between straight-through sample playback and wavetable synthesis as defined here is that the wave is not kept as a single PCM recording, but as a series of single-cycle waves (or, on later equipment like the Roland D-50, very short PCM samples) that can be played in any order or even omitted.

Wavetable synthesis is the second method, and is much, much better than FM synthesis.
Wavetable synthesis works by recording a sound sample of one note (or occasionally a few different notes) from the actual instrument, which is stored (in PCM) in the wavetable's memory.
If you where listening to a sound reproduced by FM synthesis you might ask, "Was that suppose to be a violin?" While with that same sound reproduced by wavetable synthesis you might ask, "Was that a Stradivarius violin?".

 The Wavetable Oscillator
Wavetable oscillators are often used to synthesize sounds with specified, static spectra.
While direct additive synthesis of complex waveforms, as shown in Chapter 1, is in principle infinitely flexible as a technique for producing time-varying timbres, wavetable synthesis is much less expensive in terms of computation but requires switching wavetables to change the timbre.
When using this technique to cross-fade between wavetable oscillators, it might be desirable to keep the phases of corresponding partials the same across the wavetables, so that their amplitudes combine additively when they are mixed.

 ipedia.com: Frequency modulation synthesis Article   (Site not responding. Last check: 2007-10-24)
Frequency modulation synthesis (or FM synthesis) is a form of audio synthesis where the timbre of a simple waveform is changed by frequency modulating it with a modulating frequency that is also in the audio range, resulting in a more complex waveform and a different-sounding tone.
As a result, FM synthesis was the basis of some of the early generations of digital synthesizers from Yamaha, with Yamaha's flagship DX-7 synthesizer being ubiquitous throughout the 1980s.
With the expiration of the Stanford University FM patent in 1995, FM synthesis is now part of the synthesis repertoire of most modern synthesizers, usually in conjunction with additive, subtractive and sometimes sampling techniques.

 A Tutorial on MIDI and Wavetable Music Synthesis
Digital sample-based synthesis systems may employ a variety of special techniques, such as sample looping, pitch shifting, mathematical interpolation, and polyphonic digital filtering, in order to reduce the amount of memory required to store the sound samples (or to get more types of sounds from a given amount of memory).
These sample-based synthesis systems are often called "wavetable" synthesizers (the sample memory in these systems contains a large number of sampled sound segments, and can be thought of as a "table" of sound waveforms which may be looked up and utilized when needed).
Wavetable Synthesis Techniques Looping and Envelope Generation One of the primary techniques used in wavetable synthesizers to conserve sample memory space is the looping of sampled sound segments.

Wavetable Synthesis is good because of the digital playback of digital samples.
However the real neat thing about Wavetable Synthesis is that the soundcard has the ability to "loop" a short sample, hence making a long running sample.
Many of the earlier wavetable soundcards had memory on the card that was dedicated for holding the loaded samples, and there was usually only a small amount of this memory present, or on some cards, no user writable memory at all (ie all the samples were held in ROM).

 Generations of Musical Synthesis
Analog synthesis has a sound that is often described as "fat" or "warm." It's main disadvantage is that because available analog waveforms tend to be simple, while the sounds they are simulating tend to be complex, it takes a lot of analog circuitry to accurately mimic sounds, especially during transients like key strikes.
Wavetable sythesis takes a similar approach, but tends to use the sampled instrument as more of a starting point, mixing several timbres together, or cross-fading one sound into another.
FM synthesis is based on the fact that when a frequency is modulated by another frequency, the result contains elements of both frequencies, plus new harmonics that are related to the mathematical relationship between the original frequencies.

In wavetable synthesis, a buffer is fill with samples that are then read by a pointer that circulate from the beginning of the table to the end and back to the beginning, thus creating a periodic sound.
Wavetable synthesis is very simple but unfortunately also very dull because the sound doesn't present any variation over time.
Most synthesis techniques remedy to this situation by modifying the sound after it is read from the wavetable.

Synthesis is one of the more misunderstood aspects of modern music technology.
Subtractive synthesis works by taking a source that is rich in harmonics, such as a 'sawtooth', square or pulse wave and selectively attenuating or removing these harmonics to obtain the desired timbre.
Wavetable synthesis use digital tables of sounds, frequently sampled, to provide the initial source, usually for subtractive synthesis.

In one extreme limit, "wavetables" > could just be grains triggered in a granular synthesis method, but i would call this "granular synthesis" or perhaps "wavelet synthesis" but not "wavetable synthesis".
granular synthesis is "better" (more powerful) but more expensive than wavetable synthesis, especially when the number of possibly overlapping grains is large.
Andrew Horner did research in using genetic algorithms to reduce the data set (number of wavetables) but, like the Prophet VS, he mixes more than two wavetables at a time (so it's likely that none of the wavetables stored in memory match the sound at any one time) which increases real-time computation.

The delay memory is looped and filtered, causing the initial noise burst to gradually become more harmonic as the spectral energy subsides towards the fundamental, emulating the strike-and-fade characteristics of a real plucked string.
Wavetable synthesis is a technique in which a length of memory is filled with one or more periods of a waveform; the memory is then looped during playback to produce a continuous signal.
While wavetable synthesis is extremely easy to use―no messy formulas are needed to create a musical timbre―it's somewhat limited to the extent that you don't have control over the individual elements that create the timbre (which you do with techniques such as frequency modulation).

 Sound, synthesis and audio reproduction: Sound synthesis
Synthesis products are invariably used by people with little technical background and even with such knowledge, people lack interest in tinkering with obscure settings for hours to produce the instrument they want.
Traditional wavetables still crop up, however, but not in the context of sampling synthesis—namely, they are used in additive and subtractive synths to provide the basic waveforms.
When implementing wavetable playback, one needs to start with a sampled sound and play it at a different speed, but still result in a data stream that is constant in rate.
