Audio & Sound Tools: 3 Free Online Tools
These tools handle sound and screen capture in the browser: trimming and enhancing audio, recording your screen with optional webcam and microphone, and generating test tones.
Media files can be large, so speed depends on your device. Short clips work best on phones; longer recordings are better on a desktop browser.
Who it is for: Podcasters, teachers, content creators, students and people testing speakers or headphones.

Privacy, processing and limits
- Editing and recording happen locally. The Screen Recorder asks your browser for permission to capture your screen, camera or microphone.
- Play tones at a low volume first; high or very low frequencies can be unpleasant or harmful to speakers and hearing.
