Overview of sound-fx skill

What sound-fx does

The sound-fx skill turns a text prompt into a generated audio clip: effects, foley, ambient beds, creature sounds, UI noises, and other non-speech audio. It is a good fit when you need sound-fx for Audio Editing workflows, quick prototyping, or a downloadable asset to drop into a video, game, or demo.

Best-fit use cases

Use the sound-fx skill when the task is to create a specific sound from description, not to write music or synthesize speech. It is especially useful for editors, creators, and agents that need a fast sound-fx guide for making one-off sound assets with enough control to iterate on the result.

What matters before install

The main decision points are whether you can provide a clear prompt, whether you have an API key for Noiz, and whether you want a scripted workflow instead of a generic prompt. If you need voice cloning, lyrics, or melody, this is the wrong tool; if you need a targeted sound effect, sound-fx is the right kind of skill.

How to Use sound-fx skill

Install sound-fx

Install the skill with:
npx skills add NoizAI/skills --skill sound-fx

That sound-fx install step is only the first part. The script expects a usable Noiz API key via NOIZ_API_KEY, a saved key, or an explicit command-line override.

Start from the script, then the supporting files

Read skills/sound-fx/SKILL.md first, then inspect scripts/sfx.py and ref_3rd_party.md. The script shows the real sound-fx usage path: prompt in, duration and format optional, file out. The reference file is useful if you plan to send the generated audio into Discord, Telegram, or another downstream app.

Write prompts that describe sound behavior

Good inputs describe source, texture, pacing, and context. For example, heavy rain on a tin roof, distant thunder, steady background loop will usually be more usable than rain. For sound-fx usage, include what the sound should feel like, not just what it is: short cartoon boing, elastic and bright or wooden door slam, heavy and abrupt.

Practical workflow for better results

Use a simple loop: prompt, generate, listen, revise. Start with a short clip and a focused description, then refine duration, intensity, or realism. If you are building an editing pipeline, specify the target format early, such as WAV for editing or MP3 for smaller distribution files.

sound-fx skill FAQ

Is sound-fx for speech or music?

No. The sound-fx skill is for sound effects and audio textures, not speech synthesis, singing, melody writing, or voice cloning. If your request includes spoken lines, treat it as a different workflow.

What should I read first after sound-fx install?

Read SKILL.md, then scripts/sfx.py to understand the actual inputs and output handling. If you need to move files into another app, ref_3rd_party.md shows the most relevant integration path.

Do I need to be an audio expert?

No. The skill is beginner-friendly if you can describe the sound clearly. You get better sound-fx usage by naming the action, material, intensity, and timing rather than using vague labels like “make it cool.”

When should I not use this skill?

Do not use it when you need musical composition, dialogue, or a sound that must match a specific copyrighted recording. It is also a poor fit if your prompt is too abstract to describe the actual acoustic result.

How to Improve sound-fx skill

Give the model the right audio constraints

The biggest quality gain usually comes from stronger prompt detail. Include duration, realism level, environment, and movement: 7-second low, distant factory hum with occasional metal clanks is much more actionable than factory noise. This is the fastest way to improve sound-fx output without changing tools.

Avoid vague or conflicting prompts

Common failure mode: mixing too many unrelated sounds in one request. If the output feels muddy, split the request into layers or choose one dominant event per clip. For sound-fx for Audio Editing, it is often better to generate separate elements and combine them later.

Iterate with one change at a time

After the first pass, revise only one variable: shorten the clip, change the material, or alter the mood. That makes it easier to tell whether the model is responding to your prompt or just drifting. For example, change bright cartoon whoosh to deeper, slower cartoon whoosh instead of rewriting the whole request.

Use downstream needs to shape the prompt

If the sound will be edited into a video, game, or chatbot response, say so up front. A prompt like clean isolated button click, no background noise, suitable for UI use gives the skill more useful constraints than a generic click sound. That is the kind of input that makes sound-fx guide advice actually pay off.
