Video2Audio - Custom Camera and Audio Extraction App

This SwiftUI app allows users to record videos using the device's camera and extract audio from the recorded videos. The app features a custom camera interface with recording controls and a bottom sheet that plays the extracted audio with play, pause, and stop controls.

Features

• Custom Camera Interface: Uses AVCaptureSession for video recording and displays the camera preview using AVCaptureVideoPreviewLayer.
• Recording Controls: Allows users to start and stop video recording with a single button.
