I want to create an audio visualizer based on vapi's audio output stream. Is there a way to access it from the client?

@nearLucid Absolutely, you can create an audio visualizer by accessing the audio output stream from the VAPI client. The Vapi Client SDKs are designed to handle audio streaming, and while they don't provide a direct API for visualizing audio, you can tap into the audio stream and use it as input for your visualizer. Here's a general approach you might take: 1. Use the Vapi Client SDK to establish and manage your voice calls or audio sessions. 2. Capture the audio stream from the call or session. 3. Use a Web Audio API (if you're working with a web application) or a corresponding audio processing API for iOS to process the audio stream. 4. Analyze the audio data to extract the necessary information for visualization (like frequency and amplitude). 5. Render the visualization in real-time based on the extracted audio data. For web applications, you can look into the

interface of the Web Audio API, which can be used to expose audio time and frequency data that's perfect for creating visualizations. If you need more specific guidance or have any other questions, feel free to ask!

You have to use live control feature and subscribe to audio stream over websocket, check this https://docs.vapi.ai/calls/call-features Do let me know if you have any questions @nearLucid
