Vellum Gameplay SFX

Vellum Gameplay SFX is a 6-sound set built from sine and triangle tones with no distortion at any stage. It is meant to sound like a modern phone or console interface, and every clip was synthesised from scratch for this pack — no sampled material, no library content, no model output — which is what makes it safe to hand over under a licence you can actually ship with.

Nothing in this set is loud, nothing is bright and nothing rings: the longest clip is under half a second and the room is short enough to feel like an interface rather than a space. Built to be heard hundreds of times an hour without wearing out.

Gameplay sounds have to survive a mix that already has music and ambience in it, so these run longer and carry more low end than the interface set — but they are still one-shots with the silence trimmed off, which is what keeps an impact feeling connected to the frame that triggered it.

The set covers 6 files totalling 2.7 seconds, from 304 ms (pickup) to 0.69 s (unlock). Levels are matched across it: each clip peaks at -1 dBFS with silence trimmed from both ends and a 5 ms fade, so you can drop the folder into one mixer group and set a single volume instead of balancing them one at a time.

Files are 44.1 kHz mono, 16-bit WAV masters with OGG Vorbis alongside, in wav/ and ogg/ folders. The OGG folder is 45 kB against 235 kB of WAV, so ship the OGG unless you need sample-accurate source. The WAV is the master either way — reach for it if you are going to pitch-shift or process further, because re-encoding a lossy file after processing is where artefacts come from.

Good fit for mobile games, menu-heavy strategy titles, editors and tools.
