Wavetable synthesis is a sound synthesis technique used to create periodic waveforms. Often used in the production of musical tones or notesit was developed by Wolfgang Palm of Palm Products GmbH PPG in the late s  and published in and has since been used as the primary synthesis method in synthesizers built by PPG and Waldorf Music and as an auxiliary synthesis method by Ensoniq and Access.
It is currently used in hardware synthesizers from Waldorf Music and in software-based synthesizers for PCs and tablets, including apps offered by PPG and Waldorf, among others. It was also independently developed in a similar time frame by Michael McNabb, who used it in his composition Dreamsong.
Wavetable synthesis is fundamentally based on periodic reproduction of an arbitrary, single-cycle waveform. The position in the wavetable selects the single cycle waveform. Digital interpolation between adjacent waveforms allows for dynamic and smooth changes of the timbre of the tone produced.
Creating Wavetables For Surge
Sweeping the wavetable in either direction can be controlled in a number of ways, for example, by use of an LFO, envelope, pressure or velocity. Many wavetables used in PPG and Ensoniq synthesizers can simulate the methods used by analog synthesizerssuch as Pulse Width Modulation by utilising a number of square waves of different duty cycles. In this way, when the wavetable is swept, the duty cycle of the pulse wave will appear to change over time.
As the early Ensoniq wavetable synthesizers had non resonant filters the PPG Wave synthesizers used analogue Curtis resonant filterssome wavetables contained highly resonant waveforms to overcome this limitation of the filters. Inwith the introduction of the Creative Labs Sound Blaster 16 the term "wavetable"  started to be incorrectly applied as a marketing term to their sound card.
However, these sound cards did not employ any form of wavetable synthesis,  but rather PCM samples and FM synthesis. The creation of new wavetables was previously a difficult process unless supported by specialized editing facilities and near real-time playback of edited wavetables on the synthesizer. More commonly, pre-computed wavetables could be added via memory cards or sent to the synthesizer via MIDI. Today, wavetables can be created more easily by software and auditioned directly on a computer.Can you turn a 110 outlet into a 220v
Since all waveforms used in wavetable synthesis are periodic, the time-domain and frequency-domain representation are exact equivalents of each other and both can be used simultaneously to define waveforms and wavetables.
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 padswhere 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.
It is worth noting that most wavetable synthesizers also employ other synthesis methods to further shape the output waveform, such as subtractive synthesis filtersphase modulationfrequency modulation and AM ring modulation.
On Csoundit is called f-table function tableand used for various purposes including: wavetable-lookup synthesis, waveshapingMIDI note mapping, and storing ordered pitch-class sets. Table-lookup synthesis  or Wavetable-lookup synthesis  Roads harv error: no target: CITEREFRoads help is a class of sound synthesis methods using the waveform tables by table-lookupcalled "table-lookup oscillator" technique. The length of waveforms or samples may be varied by each sound synthesis method, from a single-cycle up to several minutes.
The term " waveform table " or " wave shape table " as equivalent is often abbreviated to "wavetable",  and its derive term " wavetable oscillator "  seems to be almost same as " table-lookup oscillator " mentioned above, although the word "wave" or "waveform", "wave shape" may possibly imply a nuance of single-cycle waveform.How to reset bobcat code
However, a derive term " wavetable synthesis " seems slightly confusing. In a natural usage of words, its original meaning is basically same as " table-lookup synthesis ",    and possibly several actions on waveform s may be expected,  as seen on a paper about Karplus—Strong string synthesis  a simplest class of " wavetable-modification algorithm " known as digital waveguide synthesis .
At latest in the s, several influential sample-based synthesis products were marketed under the trade names similar to "wavetable synthesis" including Gravis Ultrasound wavetable card, Creative Wave Blaster wavetable daughterboardand Microsoft GS Wavetable SW Synthand these confusions have further affected on the several industry standards including MPEG-4 Structured Audio algorithmic and wavetable synthesis and AC97 optional hw acceleration wavetable synth .Does anyone have advice about how to do this?
Not sure how you deal with the wavetable files for each sample which presumably contain info on combining the samples. We briefly discussed wavetable synthesis in the old Google Group. As you say, treating them as oscillators makes a lot more sense. Could make for a large variety of neat new synths, maybe with a way to pick them up in a kind of catalogue.
Actual wavetable synthesis would be another approach. There, not only do you use waveforms as oscillators but you use a table concept to morph from one to another. Wolfgang Palm, who pioneered the technique, is still developing new tricks based on this.
It does sound a bit involved. But people have done it. So, anyone who has experience in Overtone and a bit of time to work on this should be able to create a new WT synth.
Would be ace! As I mentioned in that Google groups post, from my research the best synth in SuperCollider to handle this would be VOsc3 but if you literally just wanted to play the single buffer there are probably other viable approaches.
Just played around with the code in the gist. See the below code:. The real challenge I guess, is working out how to create a Wavetable in memory without having to convert a.
Understood but… would it be relatively simple to create a SPi synth from this code? And it should be more flexible than a sample.
My previous attempts with loading. Overtone is just another approach for creating supercollider synthdefs. The only thing to be aware of is that sonic Pi needs specifically named synth args as documented in the tutorial. Missed that, then.
So, my mistake.Stretch, shape and morph sounds into a broad sound palette using wavetables derived from synths, acoustic instruments, noise and much more. It brings the deeper levels of sounds design within reach, without sacrificing the profound possibilities brought by this classic form of synthesis.
Further richness comes from two morphable, flexible analog-modelled filters and a selection of unique unison modes. Click on almost any parameter and it will be added to the matrix as a modulation target, which you can then modulate with assignable envelopes and LFOs. A full breakout gives a clear overview of all controls and ample space for exploration. The oscillators offer more than wavetables: classic synths, a range of acoustic instruments, harmonic tables, various types of noise and many more.
Each oscillator has independent controls for pan, volume, and tuning, and a control to sweep through the position in the wavetable. A selection of oscillator effects, such as frequency modulation, phase distortion, pulse width, and oscillator sync, let you shape, stretch and morph each wavetable.
Plus a sub oscillator offers a sine wave — with selectable octave and adjustable additional harmonics — for adding low-end presence. Two morphable oscillators with a huge collection of wavetables are supported by an additional sub oscillator. The filters that process the raw output of the oscillators offer analog warmth and flexibility for shaping and layering sounds.
You can configure them in series, parallel, or in "split" mode — whereby each oscillator is sent through its own filter. Each filter can be switched between 12 and 24 dB slopes as well as a selection of analog-modeled circuit behaviors that emulate hardware filters found on some classic analog synthesizers. Two Cytomic-built, analog-modeled filters with a full range of filter shapes, drive and three routing options.
The heart of Wavetable's sound design power is its responsive modulation matrix. Clicking on almost any control in Wavetable will add it to the matrix as a modulation target, where it can be modulated by three envelopes, two LFOs, and a variety of MIDI sources.
Quickly add modulation to the currently selected parameter using the modulation matrix. The global section offers control over volume, toggling between monophonic and polyphonic playback and adjusting glide.
And six different types of unison behavior provide some unique sound design possibilities for stereo widening, phasing and other chorus effects. Unique unison modes add width, shimmer, noise, randomness and more.

Processing menu options allow you to do the other tasks you would want, such as apply fades, crossfades, normalize, export, and much more.
Playback of wavetables requires digital resampling to play different frequencies. Without considerable care and a whole lot of number crunching, this process will create audible artifacts. Many popular wavetable synthesizers are astonishingly bad at suppressing artifacts - even on a high-quality setting some create artifacts as high as dB to dB level difference between fundamental on artifacts which is well audible, and furthermore often dampening the highest wanted audible frequencies in the process, to try and suppress this unwanted sound.
In Serum, the native-mode default playback of oscillators operates with an ultra high-precision resampling, yielding an astonishingly inaudible signal-to-noise for instance, dB on a sawtooth played at 1 Khz at ! The modulation system allows for drag and drop connections between mod sources and destinations. Want an LFO controlling a filter cutoff?

An effects rack with 10 effects modules lets you get your sound all the way to the finish line inside Serum. Effects can be re-ordered to any configuration you want. Virtually all effect parameters are also available as modulation destinations. This is especially useful on monophonic synth sounds. Many of these effects and modes were built just for Serum, so there are many unique effects to choose from, such as Hyper, which simulates additional unison amounts, or a dual-waveshaper which allows for a distortion you can morph between two separate wave shapes.
Serum will let you stack a single oscillator to use up to 16 voices. Each of the wavetable oscillators have a number of unison advanced parameters. Stack settings allow for note e. Set the unison voices to all have their unique waveform at once with the Unison WT Pos setting, or have them all skewed in a different way with the unison Warp control.What are the Wavetables import requirements? When you start experimenting with your own wavetables, here are some guidelines that will help achieve the best results: samples per single-cycle waveform i.
This means that you can even use a sample of your voice to create a wavetable. The first samples will be placed in position 1, the second samples will be placed in position 2, and so on, until the maximum of positions has been filled.
What is a Comb filter? A comb filter adds a delayed version of the input signal to itself. It has two modes, Feedfoward, and Feedback.
These two modes results in a series of reinforced and cancelled harmonics, creating very interesting phasing effects. Comb Feedback. Note: As the effects send duplicates the signal, raising the send level will feed more signal directly to Pigments' output.

Wavetable is a sound synthesis method that compiles several single cycle waveforms in a table. These single cycle waveforms can then be played back by the engine, creating interesting timbre variations.
The browsing of the waveforms is controlled by the position parameter. Depending of your preferences, the payback can either jump or smoothly morph from one slice to another.
