Prism Variations SFX

Prism Variations SFX is a 12-sound set built from high partials with long shimmering tails and a feedback echo. It is meant to sound like crystal, ice and magic, 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.

The tails are the point. A short room would make these ordinary; instead they decay over hundreds of milliseconds with the top end left undamped, so one pickup is still ringing when the next one starts.

This is the most requested thing in game audio and the thing free packs almost never ship. A footstep played identically reads as cheap within about four steps, and the fix is not a runtime pitch randomiser, it is genuinely different takes. Each take here differs in transient timing, filter position and noise seed, and the spread is measured: far enough apart to hear, close enough to still be the same object.

The set covers 12 files totalling 13.0 seconds, from 940 ms (ui-hover-01) to 1.24 s (pickup-03). 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 117 kB against 1117 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 fantasy RPGs, puzzle games, anything with spellcasting.
