Vellum Interface SFX
====================

6 clean one-shots for the sounds an interface makes — sine and triangle tones
with no distortion at any stage. WAV masters plus OGG.

Vellum Interface 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.

Interface sounds are heard more often than anything else in a game, so this
set is deliberately quiet and short: nothing rings on after the gesture that
caused it, and no two clips sit in the same register, so a click landing on
top of a hover never turns into one smeared noise.

The set covers 6 files totalling 1.2 seconds, from 130 ms (select) to 0.32 s
(ui-confirm). 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 32 kB against 103 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.

HOW TO USE

  - Keep these on their own mixer group with a little headroom. Interface
    audio that ducks under the music is the usual reason a menu feels
    unresponsive.
  - Unity: drag the ogg/ folder into your project and set Load Type to
    "Decompress on Load" for anything under half a second, "Compressed in
    Memory" for the rest.
  - Godot: the OGG files import as AudioStreamOggVorbis with no setup — wire
    one to an AudioStreamPlayer and leave the volume at 0 dB, since the set is
    already levelled.
  - Every clip starts on its transient with no leading silence, so you can
    trigger them directly without an offset and they land tight against the
    input that caused them.
