Wavetables for Iridium / Quantum

The format Iridium / Quantum imports

On-instrument 'Import from .wav' builds wavetables from .wav/.aiff files with a constant sample period configurable from 64 to 4,096 samples (2,048 is called out as the common choice); user wavetables load, save, and exchange via microSD or USB storage.

What Hyperwave exports

Every Hyperwave export is one packed wavetable WAV. Check these facts against the Iridium / Quantum format above — where the two disagree, the fix is almost always the frame size or a conversion step, not the sound design.

Sample format

32-bit float by default (values between -1 and +1); 16-bit WAV is a direct export option for targets that load integer banks.

Channels

1 (mono). Every frame is one single-cycle waveform.

Header sample rate

48,000 Hz by default. This is a label in the file header — for wavetable import it doesn't stretch or resample your frames. One exception: VCV Rack's Wavetable VCO reads the sample-rate field as the frame length when it's a power of two, and sample players that fall back to one-shot mode use it for pitch.

Frame layout

Frames are packed end-to-end in one data chunk, in wavetable order; the export filename records the shape as name-{samples}x{frames}.wav.

Resolution

The live table runs from 8 to 8,192 samples per frame and 8 to 1,024 frames (defaults 2,048 × 256).

Metadata

No extra metadata chunks are written — targets that read frame size from metadata have to infer it from the file itself.

Load a Hyperwave table into Iridium / Quantum

1. Export from Hyperwave as a packed mono WAV with a frame size between 64 and 4,096 samples (2,048 is the common choice and Hyperwave's default).
2. Move the WAV to the instrument over USB or place it on microSD storage.
3. On the instrument, run Import from .wav and set the sample period to match your exported frame size.

Common issues

• The import's sample period tops out at 4,096 samples, so Hyperwave's 8,192-sample frames are out of range — export at 4,096 or below.
• Set the on-instrument sample period to your exported frame size; a mismatched period slices the file at the wrong length.
