• Waveform — means the shape and form of a signal such as a wave moving in a solid, liquid or gaseous medium.In many cases the medium in which the wave is being propagated does not permit a direct visual image of the form. In these cases, the term waveform… …   Wikipedia

• Waveform buffer — In computing, a waveform buffer is a technique for digital synthesis of repeating waveforms. It is common in PC sound cards.The waveform amplitude values are stored in a buffer memory, which is addressed from a phase generator, with the retrieved …   Wikipedia

• Frequency modulation synthesis — In audio and music 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 …   Wikipedia

• Direct digital synthesis — (DDS) is an electronic method for digitally creating arbitrary waveforms and frequencies from a single, fixed source frequency. OverviewA basic DDS circuit consists of an electronic controller, a random access memory, a frequency reference… …   Wikipedia

• Subtractive synthesis — is a method of subtracting harmonic content from a sound via sound synthesis, characterised by the application of an audio filter to an audio signal. For example, taking the output of a sawtooth generator and using a low pass filter to dampen its …   Wikipedia

• Additive synthesis — is a technique of audio synthesis which creates musical timbre.The timbre of an instrument is composed of multiple harmonics or partials , in different quantities, that change over time. Additive synthesis emulates such timbres by combining… …   Wikipedia

• Wavetable synthesis — is a technique used in certain digital music synthesizers to implement real time additive synthesis and direct digital synthesis with a minimum of hardware. The technique was first developed by Wolfgang Palm in the late 1970s, and has since been… …   Wikipedia

• Distortion synthesis — is a group of sound synthesis techniques which modify existing sounds to produce more complex sounds (or timbres), usually by using non linear circuits or mathematics.[1] While some synthesis methods achieve sonic complexity by using many… …   Wikipedia
