# Hyperwave

> Hyperwave (hyperwave.app) is a browser-based node-graph wavetable generator: build tables visually and export packed WAV files that load into Serum, Vital, and wavetable-capable hardware. Not affiliated with Blamsoft Expanse Hyperwave or Roland SDZ004 Hyperwave.

- Browser-based node-graph wavetable generator: tables are designed and rendered entirely in the browser, then exported as packed wavetable WAV files.
- Export container: RIFF/WAVE WAV with "fmt " and "data" chunks, written with a canonical 44-byte header (16-byte fmt chunk).
- Sample format: IEEE float (format tag 3) by default — 32-bit samples, 4 bytes each, 1 channel (mono); 16-bit PCM WAV is a direct export option for classic hardware banks.
- Header sample rate: 48,000 Hz by default (44,100 Hz selectable).
- Frame layout: single-cycle frames packed end-to-end in one data chunk, in wavetable order.
- Documented import targets: 33 total (18 software, 11 hardware, 4 modular/Eurorack). The target registry records a source check for 32.
- Glossary: 44 plain-language wavetable synthesis terms.

## When to use Hyperwave
Use Hyperwave to plan packed-WAV exports for a specific synthesizer, find source-linked wavetable import instructions, calculate frame and file sizes, or learn node-graph wavetable design. Audio editing and rendering run in the browser editor; the public API provides documentation and calculations without accessing user projects.

## Glossary
- [Wavetable glossary](https://www.hyperwave.app/glossary): all 44 definitions on one page.
- [Wavetable synthesis](https://www.hyperwave.app/glossary/wavetable-synthesis): Wavetable synthesis plays short, looping single-cycle waveforms from a table and sweeps across them to change timbre while pitch holds still.
- [Wavetable position](https://www.hyperwave.app/glossary/wavetable-position): Wavetable position is the index into a wavetable's frames that selects which single-cycle waveform, or blend of adjacent waveforms, the oscillator is currently playing.
- [Single-cycle waveform](https://www.hyperwave.app/glossary/single-cycle-waveform): A single-cycle waveform is one complete period of a periodic signal, stored as a fixed number of samples and looped by an oscillator to produce a steady pitch.
- [Wavetable frame](https://www.hyperwave.app/glossary/wavetable-frame): A wavetable frame is one single-cycle waveform occupying one slot in a wavetable; the number of frames sets how much timbral motion the table can hold.
- [Wavetable frame size](https://www.hyperwave.app/glossary/wavetable-frame-size): Wavetable frame size is the number of samples in each single-cycle frame, held constant across the whole table.
- [Interpolation between frames](https://www.hyperwave.app/glossary/interpolation-between-frames): Interpolation between frames is how a wavetable oscillator blends its two neighboring frames when position lands between them, so timbre changes continuously instead of in audible steps.
- [2048 × 256 table](https://www.hyperwave.app/glossary/2048x256-table): A 2048 × 256 wavetable (256 frames of 2048 samples each) is the de facto modern standard layout, popularized by Serum and adopted by many current wavetable synths.
- [256-sample table](https://www.hyperwave.app/glossary/256-sample-table): A 256-sample wavetable has frames that are 256 samples long. Several Eurorack wavetable modules use this frame size.
- [8×8 wavetable bank](https://www.hyperwave.app/glossary/8x8-wavetable-bank): An 8×8 wavetable bank lays 64 wavetables out on a grid, so two control signals, one per axis, scan the whole bank instead of one table's frames.
- [Morphing vs. crossfading](https://www.hyperwave.app/glossary/morphing-vs-crossfading): Crossfading is an amplitude blend between two wavetable frames, while morphing is the broader goal it serves: moving between frames so the result reads as one continuously evolving timbre.
- [Spectral morphing](https://www.hyperwave.app/glossary/spectral-morphing): Spectral morphing transitions between wavetable frames by interpolating partial amplitudes and phases instead of blending waveform samples directly.
- [Harmonics](https://www.hyperwave.app/glossary/harmonics): Harmonics are components of a periodic waveform at whole-number multiples of its fundamental frequency. The second harmonic is at twice that frequency and the third at three times it.
- [Partials](https://www.hyperwave.app/glossary/partials): Partials are the individual sine-wave components of a sound's spectrum. They include harmonics and, in sounds that contain them, inharmonic components.
- [Formant](https://www.hyperwave.app/glossary/formant): A formant is a resonant region in a spectrum that stays at roughly the same frequency as the played pitch changes. Formants help distinguish vowel sounds.
- [Phase](https://www.hyperwave.app/glossary/phase): Phase is each partial's offset within the waveform's cycle, where in the loop every sine component starts, measured as an angle rather than a time.
- [Phase distortion](https://www.hyperwave.app/glossary/phase-distortion): Phase distortion reshapes a waveform by varying the rate at which an oscillator reads it within each cycle.
- [FFT resynthesis](https://www.hyperwave.app/glossary/fft-resynthesis): FFT resynthesis analyzes a waveform with a fast Fourier transform (the algorithm that reports one magnitude and phase per frequency slot), edits that spectrum, and rebuilds a waveform from it with the inverse transform.
- [Resynthesis](https://www.hyperwave.app/glossary/resynthesis): Resynthesis is analyzing an existing sound and rebuilding it as a wavetable, converting spans of the source into single-cycle frames rather than playing back samples.
- [Waveshaping](https://www.hyperwave.app/glossary/waveshaping): Waveshaping passes a signal through a transfer curve. It computes each output sample from an input sample to change the waveform's harmonic content.
- [Wavefolding](https://www.hyperwave.app/glossary/wavefolding): Wavefolding is a waveshaping technique that reflects a signal back on itself once it passes a threshold, multiplying harmonics without changing the fundamental.
- [Hard sync](https://www.hyperwave.app/glossary/hard-sync): Hard sync is an oscillator arrangement in which a master oscillator resets a second, detuned oscillator every time the master completes its own cycle, producing a biting, formant-rich tone.
- [Through-zero FM](https://www.hyperwave.app/glossary/thru-zero-fm): Through-zero FM is frequency modulation in which the carrier's frequency is allowed to pass through zero and come out negative, continuing the phase in reverse rather than stopping.
- [Pulse-width modulation](https://www.hyperwave.app/glossary/pwm): Pulse-width modulation (PWM) varies a pulse wave's duty cycle. The duty cycle is the fraction of each cycle spent at its high level, and changing it changes the timbre.
- [Formula-generated wavetable](https://www.hyperwave.app/glossary/formula-generated-wavetable): A formula-generated wavetable has frames computed from expressions evaluated per sample and per frame.
- [Aliasing](https://www.hyperwave.app/glossary/aliasing): Aliasing is inharmonic distortion that appears when a digital signal contains frequencies above half the sample rate (Nyquist), which reflect back down into the audible range.
- [Band-limiting](https://www.hyperwave.app/glossary/band-limiting): Band-limiting restricts a waveform's harmonics to frequencies below the Nyquist limit, which is half the sample rate.
- [DC offset](https://www.hyperwave.app/glossary/dc-offset): DC offset is a nonzero average level in a waveform. The cycle sits above or below zero instead of being centered on it.
- [Wavetable bank](https://www.hyperwave.app/glossary/wavetable-bank): A wavetable bank is a grouped collection of wavetables that an instrument loads together and offers under a single browser or selector.
- [WAV file](https://www.hyperwave.app/glossary/wav-file): A WAV file is the everyday audio container: a header describing the format, a block of sample data, and room for extra metadata chunks.
- [Packed wavetable WAV](https://www.hyperwave.app/glossary/packed-wavetable-wav): A packed wavetable WAV is a single audio file that stacks every frame of a wavetable end to end, so a wavetable-capable synth can import the whole table from one file.
- [clm chunk](https://www.hyperwave.app/glossary/clm-chunk): The 'clm ' chunk is optional metadata in some Serum-format wavetable WAV files; plain WAV exports may omit it.
- [srge chunk](https://www.hyperwave.app/glossary/srge-chunk): The 'srge' chunk is Surge XT's own versioned metadata chunk inside WAV files, telling its importer the frame layout the same way Serum's 'clm ' chunk does.
- [wt file](https://www.hyperwave.app/glossary/wt-file): A .wt file is Surge XT's native wavetable format: a short tagged header followed by the table's frames as raw samples, optionally trailed by metadata.
- [vitaltable file](https://www.hyperwave.app/glossary/vitaltable-file): A .vitaltable file is Vital's native wavetable format. It is a readable JSON document describing how the table was built instead of storing only rendered audio.
- [uhm format](https://www.hyperwave.app/glossary/uhm-format): A .uhm file is a u-he Hive wavetable script: a readable text file of commands and formulas that Hive evaluates step by step to build a wavetable.
- [Additive synthesis](https://www.hyperwave.app/glossary/additive-synthesis): Additive synthesis builds a sound by summing sine-wave partials. It sets each component's amplitude and, optionally, its phase.
- [Subtractive synthesis](https://www.hyperwave.app/glossary/subtractive-synthesis): Subtractive synthesis starts with a harmonically rich waveform and removes or reduces parts of its spectrum with filters.
- [Granular synthesis](https://www.hyperwave.app/glossary/granular-synthesis): Granular synthesis builds sound from many short grains. Each grain is a brief, windowed slice of an audio buffer played at a chosen time and pitch.
- [Wave sequencing](https://www.hyperwave.app/glossary/wavesequencing): Wave sequencing plays a programmed series of waves within one note. The Korg Wavestation supports up to 255 steps with settings for duration, pitch, and crossfade.
- [PPG Wave](https://www.hyperwave.app/glossary/ppg-wave): The PPG Wave is the synthesizer line that introduced commercial wavetable synthesis, built by Wolfgang Palm's Palm Products GmbH from 1981 to 1987.
- [Waldorf Microwave](https://www.hyperwave.app/glossary/waldorf-microwave): The Waldorf Microwave (1989) is the rack synthesizer that carried PPG's wavetable lineage forward after PPG closed, pairing wavetable scanning with an analog filter.
- [Korg DW-8000](https://www.hyperwave.app/glossary/korg-dw-8000): The Korg DW-8000 (1985) is a hybrid synthesizer with 16 stored digital waveforms and an analog filter. Its DWGS oscillators select a fixed waveform rather than scan a wavetable.
- [Ensoniq Transwave](https://www.hyperwave.app/glossary/ensoniq-transwave): A Transwave is Ensoniq's variant of wavetable scanning. Instruments such as the VFX, TS, and Fizmo sweep stored waves with programmable start, end, and loop points.
