Line 18:
*[[LA synthesis]] uses short [[Pulse-code modulation|PCM]] samples for the attack portion of the sound, with either a digital subtractive synth sound or looped samples (most of them single-cycle loops) for the sustain/release portion of the sound.
*[[Granular synthesis]] uses many overlapping [[Window function|windowed]] samples. While these samples are very short, they are never periodic.
 
=== Confusion with table-lookup oscillators ===
[http://en.wikipedia.org/wiki/Numerically_controlled_oscillator Numerically controlled oscillators] often employ digital memory to store samples of single-cycle waveforms. This type of short-memory based oscillator has also become known as a wavetable oscillator.
 
=== Confusion with sample-based synthesis===
Starting around 1993, with the introduction of Creative Labs' [http://en.wikipedia.org/wiki/Sound_Blaster_AWE32 Sound Blaster AWE32] and Gravis' [http://en.wikipedia.org/wiki/Gravis_Ultrasound Ultrasound] [http://en.wikipedia.org/wiki/Sound_cards sound cards], the term "wavetable" started to be applied as a marketing term to any sound card that used [[pulse-code modulation|PCM]] samples as the basis of sound creation. However, these sound cards did not employ any form of wavetable synthesis, but rather a [[sampler (musical instrument)|sampler]] and [[subtractive synthesis]] system based on technology from the [[E-mu Emulator]] series of digital sampling keyboards.
