Prism Ambience SFX
==================

3 crystalline seamless loops for a place when nothing is happening — high
partials with long shimmering tails and a feedback echo. WAV masters plus OGG.

Prism Ambience SFX is a 3-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.

An ambience bed is judged on one thing: whether it loops without a click. That
is harder than it sounds, because a fade at each end is not a loop, it is a
gap. These beds are built so the tail sums back into the head and every
modulation completes a whole number of cycles inside the loop, and the build
measures the discontinuity at the wrap point and refuses anything audible.

The set covers 3 files totalling 24.0 seconds, from 8000 ms (wind) to 8.00 s
(wind). 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 283 kB against 2067 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.

HOW TO USE

  - Set these to loop with no crossfade. A crossfade on an already-seamless
    loop shortens it and introduces the very artefact it is meant to prevent.
    Keep them well under the one-shots in the mix; ambience that competes with
    an interface click is ambience nobody notices except as fatigue.
  - 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.
