== Wavetable synthesis is not sample playback ==
In the 1990s, companies like [https://en.wikipedia.org/wiki/E-mu_Systems E-mu Systems] and [https://en.wikipedia.org/wiki/Creative_Technology Creative Technology] marketed their "PCM sample playback" or "[[Rompler|ROMpler]]" technology, which involves playing back pre-recorded samples stored in ROM, as "Wavetable synthesis." Traditionally, wavetable synthesis involves manipulating single cycle waveforms to generate sounds. This marketing approach led to some confusion, as the technologies are fundamentally different in their sound generation methods.
== Wavetable synths ==
Wavetable synthesis has been the primary synthesis method in synthesizers built by PPG and Waldorf Music, has been used for the [
== Principle ==
Wavetable synthesis is periodic reproduction of a single-cycle [[waveform]].<ref>''[
Both variable and (more commonly) fixed sample rate systems are used<ref>''Practical Considerations in the Design of Music Systems using VLSI'' by J. William Mauchly, Albert J. Charpentier, Audio Engineering Society (AES), AES 5th International Conference: Music and Digital Technology, 1987</ref> and the wave modulation rate is usually significantly smaller (slower) than the [[sample rate]]. Depending on the details of the actual implementation, the sound produced by wavetable synthesis may also contain recognizable artifacts, especially [[aliasing]], [[quantization error]]s, and [[phase truncation]] noise.
Line 22 ⟶ 28:
During playback, the sound produced can be harmonically changed by moving to another point in the wavetable, usually under the control of an [[envelope generator]] or [[low frequency oscillator]] but frequently by any number of modulators (matrix modulation). Doing this modifies the harmonic content of the output wave in real time, producing sounds that can imitate acoustic instruments or be totally abstract, which is where this method of sound creation excels. The technique is especially useful for evolving [[synth pad]]s, where the sound changes slowly over time.
It is often necessary to 'audition' each position in a wavetable and to scan through it, forwards and backwards, in order to make good use of it, though selecting random wavetables, start positions, end positions and directions of scan can also produce satisfyingly musical results. Most wavetable synthesizers also employ other synthesis methods to further shape the output waveform, such as [[Voltage controlled filter|filters]]
