Frequently Asked Questions
Everything you need to know about processing files securely in your browser
How do I record audio using this tool?
Grant microphone permission when prompted by your browser, select the desired microphone from the dropdown list, and click the circular Record button. Click it again or click Stop to end recording and generate a WAV file.
Do I need to sign up or download software to record?
No. This tool is completely free, does not require registration or any account, and runs fully in-browser without extensions or external apps.
Are my voice recordings uploaded to a server?
No. The audio data from your microphone is recorded directly to your browser's temporary memory using the MediaRecorder API. Your recordings never leave your device, ensuring total privacy.
What format is the downloaded audio saved in?
All recordings are saved as high-quality, lossless 16-bit PCM WAV files, preserving the exact audio stream captured by your microphone.
Is there a limit on how long I can record?
There is no hard limit set by the tool, but since recordings are cached in your browser's local memory (RAM), very long recordings (longer than an hour) depend on your device's available memory resources.
