Frequently asked questions
What’s a voice isolator AI?
Voice isolator AI is a tool in Captions that helps your voice stand out by removing background noise and echo from your recordings. Think of it like a filter for your audio — it keeps your voice clear and easy to understand, even if you're recording in a noisy space. It’s perfect for creators who want studio-grade audio without needing fancy gear or editing skills.
Do I need special hardware to use the voice isolator AI tool?
No — you don’t need any special equipment to use this tool. Our voice isolator works right inside the Captions app, whether you're editing on your phone, tablet, or computer. It’s designed to give you studio-quality sound without needing a soundproof room. If you have a device with a mic and the Captions app, you’re good to go.
How does AI sound effects generation work?
AI sound effects generation uses artificial intelligence to create or enhance sounds based on text prompts. For example, if you’re filming a nature vlog, you might create a subtle outdoor ambiance to match the mood. Captions makes it very simple: Describe what you want with a short text prompt, and the AI handles the rest.
Is Captions’ voice isolator AI compatible with all devices?
Yes — our voice isolator works across devices that support the Captions app. Whether you're on iOS, Android, or desktop, the tool is optimized for easy use. It doesn’t require advanced specs or expensive hardware, so it's accessible for beginners and pros alike.
Do I need any audio production skills to use Captions’ AI voice isolator?
Not at all. Captions is designed for everyday creators, not sound engineers. You don’t need any experience with audio software to use the voice isolator — just upload your content and tap “Denoise.” The tool handles the tech details in the background. It’s intuitive and beginner friendly, helping anyone sound like a pro with minimal effort.
Can the voice isolator AI remove all background noise?
Our voice isolator does an impressive job of cutting out most unwanted sounds, like echoes or crowd murmur. No tool can eliminate every noise, but Captions gets impressively close.
Any project can benefit — for example, ASMR videos require near silence in the background, while reaction videos also come out better when the environment is quiet. Voice isolation is a great fix for noisy audio, especially when rerecording isn’t an option
