How to import wavetables into Serum 2

What Serum 2 expects

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.

Step by step

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.

If something goes wrong

Why does my imported WAV sound different in Serum 2?

Serum 2's import methods analyze or transform audio differently. Inspect the chosen method and resulting frames. For a recording made from 2,048-sample cycles, Xfer recommends entering 2048 in the Formula field before dragging to avoid resampling.

Only part of my table arrives.

Files over 256 frames exceed the 2 MB table limit. Export at 256 frames or fewer.

Export settings for Serum 2

Serum 2 has no dedicated export preset in Hyperwave — the default preset ("Default — 2048 × 256") writes 2,048 samples per frame, 256 frames, mono 32-bit float, and matches the layout documented above.

Default — 2048 × 256

2,048 samples per frame × 256 frames · 32-bit float · 48 kHz
