Wavetables for Serum 2

The format Serum 2 imports

Serum 2's Wavetable Editor imports audio files through its Import menu or file drag-and-drop. Its internal wavetable layout uses 2,048 samples per frame and up to 256 frames (2 MB of 32-bit sample data). Import methods include Dynamic Pitch, Frequency Estimation, Constant Framesize, and FFT; the selected method can change the source data.

What Hyperwave exports

Every Hyperwave export is one packed wavetable WAV. Check these facts against the Serum 2 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). Single-table and collection exports can render 8–16,384 samples per frame and 1–256 frames.

Metadata

Hyperwave writes no extra wavetable metadata chunks. Importers use the audio layout, their own defaults, or settings you choose to interpret the frames.

Load a Hyperwave table into Serum 2

1. Export from Hyperwave as a packed mono WAV at 2,048 samples per frame, up to 256 frames.
2. Open Serum 2's Wavetable Editor, choose Import, and select the WAV and an import method. The editor also supports dragging an audio file into Serum.
3. Inspect and audition the imported frames. If you import a recording made from 2,048-sample cycles by dragging, Xfer's manual recommends entering 2048 in the Formula field first to avoid resampling.

Common issues

• Serum 2 offers several audio-import methods that can analyze or transform the source. For a 2,048-sample-cycle recording, Xfer's manual says to enter 2048 in the Formula field before dragging to avoid resampling; inspect packed-table imports after choosing a method.
• Files over 256 frames exceed the 2 MB table limit — export at 256 frames or fewer.
