Hyperwave / Features
Hyperwave is a free wavetable generator that runs in your browser. Build a node graph from oscillators, audio, additive partials and math. Control how the sound changes across frames, inspect each stage, and export a wavetable for your software synth or hardware.
These features are available in the Web app. No installation or account is required for local generation and export.
Generate waveforms from oscillators, noise, curves and mathematical operations.
Start with a Waves or Noise source, or build a signal from coordinates and math. Connect it to the output, then add processing. You can return to the source settings at any time.
Build a waveform from harmonic partials with amplitude and phase control.
Set partial levels and phases in the Additive source. You can inspect the waveform and pass it through other nodes.
Import browser-decodable audio and slice it into single-cycle wavetable frames.
Load source audio, choose its frame layout, inspect the slices and process the resulting table. The separate free converter also makes packed WAV files from audio.
Drive parameters with Wavetable Index, curves and math to generate an evolving sequence.
Connect Wavetable Index to a parameter, shape its values with a curve or math, and scan through the table. Each branch of the graph can change in its own way across the sequence.
Split sources into parallel paths and recombine them with signal and spectral operations.
Send a source through several branches. Blend them with Mix, multiply or subtract them, or combine their spectra using the available mixing and phase modes.
Process each spectral bin's amplitude, phase and harmonic position inside a Spectral Graph.
Convert a signal to spectral data and open a Spectral Graph. Connect rules to its amplitude, phase and harmonic outputs, then convert the result back to a signal for further processing or export.
Draw a spectral EQ curve or morph a Spectral Filter continuously from low-pass through band-pass to high-pass.
Draw a frequency curve in Spectral EQ. To change the filter across a table, connect controls to the Spectral Filter's shape, cutoff, slope or resonance.
Generate new harmonic material with waveshaping, distortion, folding, phase operations and filters.
Place a shaper or filter after a source and drive its parameters across Wavetable Index. Branch before the processor when you want to mix the processed signal with its original input.
Feed a processing result into the next pass inside a bounded Feedback Graph.
Give Feedback Graph a starting signal, build an operation inside it and choose the number of passes. Use the original input, previous result, pass index and progress to control each pass.
Inspect intermediate nodes and the final output with waveform, harmonic and phase views.
Select a node to examine its contribution, compare it with the final table and scrub through frames. Use these views to find cancellation, abrupt transitions or unwanted spectral changes.
Export packed mono WAV wavetables as 32-bit float or 16-bit PCM.
Choose the frame size, frame count and sample format for your destination, export a WAV and import it into your synth. Use the format reference and device guides for the receiving instrument's requirements.
Render several saved presets locally and bundle their wavetable WAV files into a ZIP.
Put your presets in a collection, choose an export layout and render them together.
Save the generating graph as a preset and organize reusable processing in graph scopes.
Save a preset locally, then reopen it to change the source or an earlier rule. Connected nodes regenerate from your changes. Nested scopes help organize larger graphs.
Follow a built-in tutorial to learn one wavetable-generation recipe.
Open the app's getting-started tutorial, follow the steps and then adapt the resulting graph. The written tutorials separately cover audio preparation and export workflows.
Let an MCP-connected assistant discover nodes, construct a temporary preset with you and render its output.
Connect a compatible assistant to Hyperwave's product MCP server. It can create a temporary session and share an editor link with you. While you work in the browser, the assistant can inspect controls, edit the graph and render bounded audio.
