openverse-sfx
From the author
Add a licensed soundtrack to any video for $0 with beat-matched music, Openverse sound effects, -16 LUFS mastering, and FFmpeg verification. Searches 5.2M free CC0/CC-BY/public-domain audio files (no API key), aligns cuts to the kick-drum beat grid with librosa, peak-normalizes SFX one-shots, verifies the exported MP4 with ebur128 and cue frame grabs, and auto-writes credits.txt. Trigger when the user says "add sound to this video", "add music to my video", "add sound effects", "find free SFX", "sound design this clip", "my video needs audio", or "add audio to my ad".

- sfxmintsickn33/agentic-awesome-skillsFind and add free CC0 sound effects to an app, game or video by event, set or description over a keyless API or MCP; generate a missing sound with an API key.Media★ 49K
- suggest-sfxhassancs91/claude-faceless-shorts-creatorThe SFX pass. Analyze a short's beats + narration and propose tasteful sound effects synced to them, drawing from (and growing) a shared, reusable SFX library, then render an SFX-mixed audition preview. Use when the user wants to "add SFX / sound effects", "suggest sfx", "score the transitions", "sound-design this beat", generate/source sound effects, build or extend the sfx library/catalog, author or audit a sfx-plan, or mix SFX over a rendered short in this repo. Covers reading beats + word times + brand §7, the library-first flow, generating misses with the ElevenLabs Sound Effects API, the per-video sfx-plan.json, the hard user-audit gate, and mixing with tools/mix_sfx.py (light voice ducking).Design★ 292
- video-to-sfxsonilo-ai/skillsGenerate sound effects matched to a video using Sonilo — footsteps, impacts, ambience, foley — optionally scripted to specific timed segments, returning either the audio or a new video with the SFX muxed in. Use when the user has footage that needs sound design. For SFX from a text description alone, use the text-to-sfx skill; for music, use video-to-music.Media★ 117
- soundhashgraph-online/awesome-codex-pluginsMake a game's sound effects and synthesized music on the creator's own computer, free, with no provider or account — a set of effects (jump, coin, hit, explosion, win, lose, UI) rendered from presets, a short synthesized theme or score from chords and patterns with stems and seamless section loops, a mix of any audio files and expressions — measured for loudness, clipping, late starts and what a phone speaker loses, then wired into the game with a small player that starts on the first touch and switches music on bar lines. Use when someone asks for sound effects, SFX, game audio, a chiptune or synth theme, background music without a paid service, music that changes with the game, or says a game is silent.Design★ 1.5K
- soundzasickn33/agentic-awesome-skillsFind, audition and add free sound effects, ambience or music to a game, video or app with Soundza, or generate a new sound effect from a prompt, over MCP or a REST API.Media★ 49K
- text-to-sfxsonilo-ai/skillsGenerate a sound effect from a text description using Sonilo — a UI chime, a whoosh, an impact, ambience, a stylized cue — when there is no video to match. Use when the user describes the sound they want in words, with or without a length. For SFX matched to footage, use the video-to-sfx skill; for music, use text-to-music.Design★ 117
