# Burbz audio pack — attribution and licences This directory contains a compact game-ready sound pack, the Burbz Quest background tracks, and an Empire-view ambience. The original short sound pack has Ogg Vorbis preservation copies and MP3 runtime copies. The bespoke 2026 Burbz runtime sounds, score, and ambience were generated as MP3 files with ElevenLabs. The two field recordings were excerpted, high-pass filtered, and given short boundary fades. The audio licences below apply to the corresponding audio files. This document is not legal advice. No original creator or licensor endorses Burbz. ## File manifest | Burbz file | Intended sound | Duration | Bytes | SHA-256 | |---|---|---:|---:|---| | `ui-book.ogg` | book / page movement | 0.884898 s | 10,353 | `8161e8c99a9a8caffee8480e31280df25078f34ff29a9b5abbbb011d101a52c1` | | `ui-lock.ogg` | lock mechanism | 0.397279 s | 5,920 | `a9d76462b89978e1c91a5a520d86ddcc350645038444990b203440642864a833` | | `ui-coins.ogg` | coins / reward pickup | 0.482381 s | 8,155 | `d68e5396e243afe5e09040d737ebc73a3b23b162ff6163a29cbc23f1e23df31f` | | `ui-wood.ogg` | wood impact | 0.298073 s | 5,604 | `8706ca78490479664929e4f37a0c618be921127a0d2be9fc5819f619c8fdbc5a` | | `ui-metal.ogg` | metal impact | 0.564308 s | 8,090 | `d65c52d7021302e7ec4611b9d10dd1683d74c02eda25060545783a21ecb873c2` | | `ui-spell.ogg` | fantasy spell accent | 0.632993 s | 8,678 | `6e7831373defc155004810b1fd18239e8aaf2c4a2944f0b517c172c87a345d20` | | `reward-level-up.ogg` | reward / level-up sting | 1.555737 s | 10,630 | `c8e5aacb3a9a23bdef701f235d76331f9ebf67573c67af0109508fe3759e7205` | | `bird-blackbird.ogg` | real common blackbird song | 2.200000 s | 21,153 | `fead210199b57e3dc9bceb12fe5b0a9e8ba99b5f4a52e3248322068bba6c4ac0` | | `bird-tawny-owl.ogg` | real tawny owl call | 2.200000 s | 20,857 | `ae1a55eadbd20ba9e64a620c3a1138e6857b3afd76e546876b0c66ca50cd9336` | | `bgm-birbs-quest.mp3` | looping instrumental background music | 60.029375 s | 1,457,390 | `3a194db0479c278513ecb1c95d0705fe8c6b0ea614821baf0185c5cb9611206e` | | `bgm-burbz-quest-v2.mp3` | crossfaded instrumental background music | 120.032625 s | 2,897,468 | `59485a4e859c55f5f7917353b5b270690b146cc71ceab9c72b22631964c5a9a2` | | `ambience-empire-treetops.mp3` | seamless Empire-view treetop ambience | 30.000000 s | 721,197 | `5b767068cd3d6df32e740f0dc052a76210a6aa231e668458d23220f40232a543` | | `sfx-ui-tap.mp3` | wood-and-feather interface tap | 1.000000 s | 25,389 | `8b538d448fcaf6cac8feb7840d9e3a4d54470ebbdf4b7b9e87a724aa195ca19a` | | `sfx-page-wing.mp3` | parchment and wing navigation movement | 1.000000 s | 25,389 | `017bd56044e8cb2a92d29d5d53237edcbab60f16b6b4de5e0d3617d14c1f8d5a` | | `sfx-capture.mp3` | magical bird capture | 1.000000 s | 25,389 | `aac7037e11427e0ba06e72bbaeae4483f11e4d028b4f4b40d34d0f575c8e3d24` | | `sfx-resource.mp3` | wooden seed-token resource pickup | 1.000000 s | 25,389 | `d9c113cdc6fe66e9b37641721ee506798d6c483edc1f8a35f1892c041a5671ab` | | `sfx-battle-hit.mp3` | feathered wooden battle impact | 1.000000 s | 25,389 | `493a3940f9a608023cfce0b020d9bd770e541e21e7e18f34b9f8175c3bf06baf` | | `sfx-battle-magic.mp3` | wind-magic battle impact | 1.000000 s | 25,389 | `adaf3c49e58dca884935f978620c7dcdeab2e31beddf11790c3419aba5d01f4b` | | `sfx-battle-defend.mp3` | wooden shield and wing guard | 1.000000 s | 25,389 | `ad01d6349b077d7fe6a77f9188258a4c0c6ecc6d474a0d24570a65b4421350c3` | | `sfx-build.mp3` | hand-built wooden perch | 1.000000 s | 25,389 | `df65c0848b4312e711b5a49b097493a64a0e4c2197abe4cb49494ddf5dd4d00a` | | `sfx-level-up.mp3` | woodland level-up flourish | 1.000000 s | 25,389 | `e1eea51f04c48d758f1f9baf75a99b21c7d36f2bf9d9b395a3262e4a2a2621ad` | | `sfx-quest-complete.mp3` | magical quest-complete seal | 1.000000 s | 25,389 | `52beba5ddebdd2885b47597ab46e6f38b0d1ae3ed6913d8293094cdaa562cee7` | | `sfx-victory.mp3` | restrained woodland victory sting | 1.000000 s | 25,389 | `51dbc40894dbf8c15b183f5c41083a5e87b3d7f692057d69a640cf38ab8cf26a` | | `sfx-defeat-error.mp3` | gentle defeat and error feedback | 1.000000 s | 25,389 | `2707e1e5fb7971ff5a3853fd617d3bf758dd3f6f12f8c9d5b0f956ca7b5c2bbc` | Short-SFX Ogg preservation payload: **99,440 bytes**. Short-SFX MP3 runtime payload: **118,264 bytes** (documentation excluded). Each short-SFX `.mp3` file is a 96 kbps runtime conversion of the same-basename `.ogg` adaptation and carries the same licence and attribution. ## Burbz Quest background music and bespoke sound design `bgm-birbs-quest.mp3`, titled **Burbz Quest**, is an original instrumental generated with ElevenLabs and supplied by the Burbz project owner on 25 July 2026 for use as the game's looping background music. The approved source file was `Birbs_Quest_2026-07-25T151737.mp3`; it was renamed for the runtime without altering its bytes. Its use remains subject to the project owner's ElevenLabs account and applicable service terms. `bgm-burbz-quest-v2.mp3` is a new two-minute **Burbz Quest** instrumental generated with ElevenLabs on 26 July 2026. It was prompted as a warm, hand-crafted woodland fantasy score with a loop-friendly opening and ending. The runtime overlaps two audio decks for a five-second crossfade at each loop. `ambience-empire-treetops.mp3` and the twelve `sfx-*.mp3` files were generated specifically for Burbz with ElevenLabs on 26 July 2026. Their shared sound direction uses polished wood, parchment, feathers, wind magic, restrained chimes, and natural treetop textures rather than arcade-style effects. The ambience was generated in ElevenLabs' seamless-looping mode. Their use remains subject to the Burbz project owner's ElevenLabs account and applicable service terms. The generated ambience and short cues were peak-normalized to approximately -3 dBFS for consistent game playback without changing their timing. ## 80 CC0 RPG SFX Files in Burbz: - `ui-book.ogg`, derived from `book_02.ogg` - `ui-lock.ogg`, derived from `lock_02.ogg` - `ui-coins.ogg`, derived from `item_coins_03.ogg` - `ui-wood.ogg`, derived from `wood_03.ogg` - `ui-metal.ogg`, derived from `metal_02.ogg` - `ui-spell.ogg`, derived from `spell_01.ogg` Creator: **rubberduck** Work: **80 CC0 RPG SFX** Source page: Source archive: Licence: **CC0 1.0 Universal (public-domain dedication)** Licence text: Attribution is not required by CC0, but the creator and source are retained here for provenance.
