In-App Audio Generation (ElevenLabs)

This skill provides guidelines and a generalized Python script to generate high-quality sound effects for game development and UI interactions (clicks, hovers, win states, errors, notifications, etc.) using the ElevenLabs Sound Effects API.

Best Practices for UI / Game Prompt Engineering

When crafting prompts for ElevenLabs, keep the following rules in mind:

1. Describe the Physical World: Give context (e.g., "digital", "mechanical", "8-bit", "natural", "abstract"). This shapes the texture.
2. Utilize Audio Descriptive Adjectives: Use audio terminology like "warm", "crisp but gentle transient", "clean attack", "no harsh highs", "low-mid pitch".
3. Set the Emotional/Functional Context: Tell the AI what the sound is for (e.g., "playful game aesthetic", "functional UI error rejection", "bouncy confirm sound").
4. Target Short Durations: For UI sounds, a duration of 0.5 to 2.0 seconds is ideal. Let it generate just enough to hit cleanly without a massive tail.
5. Prompt Influence: Use a lower prompt influence (0.3 to 0.5) for Sound Effects rather than voices. This allows the model creative leeway to synthesize rather than overly strictly failing to map the prompt to real physics.

Examples of Great UI Prompts

• Menu Confirmation: "bright, bouncy confirm sound with a soft plucky transient, cheerful upward tone, light cartoon-like sparkle, playful game aesthetic, clean attack, no harsh highs"
• Error / Invalid: "short beep with low-mid pitch, muted mechanical tone, crisp but gentle transient, slight downward interval to signal rejection, no reverb, functional UI aesthetic"
• Notification / Hover: "gentle two-tone chime with warm digital bell texture, smooth attack, ideal for menu transitions"
