Define the Source
Describe the primary action (e.g., "Heavy footsteps") and select a material texture (e.g., "on gravel"). This sets the physical foundation of the sound.

How CineFoley works
CineFoley bridges the gap between narrative intent and AI audio generation. It builds precise, multi-dimensional prompts that control the source, space, and cinematic texture of your soundscape.
Quick start
Design your soundscape in three moves
CineFoley is a free prompt builder — assemble a soundscape and copy the optimized text into platforms like Stable Audio, AudioLDM, MMAudio, ElevenLabs SFX, or Suno SFX with no account or key. It can also render the audio for you directly in the browser via fal.ai Stable Audio. That optional generation step uses your own fal.ai API key, billed to you and stored only in your browser.
Set the Space
Choose the acoustic perspective (Close-Up to Distant) and the environment (Studio to Cavern). This places the sound within your scene's geometry.
Layer Modifiers
Add cinematic vibe, technical quality, and hardware character. Then either copy the optimized prompt into your target engine, or hit Generate SFX to render it in-browser via fal.ai with your own key.
Methodology
Sonic Architecture
CineFoley uses a five-layer assembly process to ensure AI models understand the complexity of real-world acoustics.
The Five Dimensions
Every prompt is a combination of these layers, weighted for maximum clarity in both natural language and tag formats.
- Source The physical action and material contact.
- Space Proximity and environmental reverb.
- Timing The pacing and duration of the event.
- Tone Cinematic vibe and technical fidelity.
- Hardware The microphone and recording chain character.
Format Optimization
Switch between a Natural Prompt and a Tag Prompt. Each mode rearranges the logic for different audio engines and copy targets.
Tip
Tag prompts are often superior for loops and ambient beds, while natural prompts excel at narrative, one-shot foley impacts.
Controls
Mastering the acoustic signature
Templates
Use Quick Start Templates like Cyberpunk City or Nature ASMR to instantly load a coherent state. It's the fastest way to learn how different cards interact.
Pacing
Control the evolution of the sound. Continuous Loop is perfect for beds, while Slowly Evolving adds subtle movement over longer durations.
Cinematic Modifiers
Add "Punchy" for impacts or "Lo-Fi / Tape" for vintage character. These tags guide the AI toward the specific aesthetic of your film's sound design.
Quality Boosters
Specify 48kHz, Stereo Field, or Lossless. While AI generation isn't always true lossless, these tags signal the model to prioritize high-frequency clarity.
Negative Prompts
The most important tool for control. Use it to exclude unwanted elements like "music" or "wind" when you only need a specific mechanical sound.
Hardware Character
Simulate specific recording chains. A "Shotgun Mic" perspective feels different than a tactile "Contact Mic" or a rough "Phone Voice Memo".
Professional Workflow
Advanced Layering
Avoid Audio Drift
AI audio models can "drift" toward music or noise in long generations. Use aggressive negative prompts and choose "Repeating" pacing to keep the model focused.
Layering in Post
Instead of one complex prompt, generate three simple ones: a dry impact, a room tail, and a background texture. Blend them in your NLE for total control.
Favorites Library
Save your best setups to your local Favorites. This creates a personal preset bank that persists across browser sessions for recurring project needs.
Distance Perspective
Pair "Distant" proximity with "Large Hall" or "Forest" reverb to create deep spatial depth that pushes sounds behind your dialogue.
