Sine Ascent

Spectral wavetable · fntn7b6g

Play it on your computer keyboard: A–K (white keys), W E T Y U (black keys), Z/X octave down/up.

Begins as a near-pure, rounded tone and gradually opens into a fuller, more harmonically active voice as the frames advance. The change is smooth and continuous, with no grain or noise, giving a gentle swell that brightens noticeably at higher octaves.

Free spectral wavetable for pad, drone, 256 frames, royalty-free.
