No. All audio recording and WAV conversion happens entirely in your browser. Nothing is uploaded to any server. Your privacy is fully protected — recordings exist only in your device's memory until you choose to download or clear them.

WAV (Waveform Audio File Format) is an uncompressed, lossless audio format developed by Microsoft & IBM. It preserves audio quality perfectly with no compression artifacts, making it ideal for professional use, editing, archiving, and situations where audio fidelity is paramount. File sizes are larger than MP3, but quality is pristine.

All modern browsers are supported: Chrome 49+, Firefox 50+, Edge 79+, Safari 14.1+, Opera 36+. Safari on iOS requires HTTPS. The tool uses the standard MediaRecorder API. For the best experience, we recommend using the latest version of Chrome or Firefox on desktop.

The WAV file uses the same sample rate as your microphone (typically 44.1 kHz or 48 kHz) with 16-bit PCM encoding. This is CD-quality audio. The exact sample rate depends on your hardware and browser, and is preserved during conversion to ensure no quality loss.

Yes! Click the Pause button or press Space while recording to pause. Press Resume to continue. Only the actual recorded duration counts — pauses are excluded. All paused segments merge seamlessly into one continuous WAV file when you stop.

As a rule of thumb: 1 minute of mono 44.1kHz 16-bit WAV ≈ 5.3 MB. Stereo doubles that (~10.6 MB/min). For example, a 10-minute mono recording produces roughly a 53 MB WAV file. The tool shows the estimated file size for each recording in the list.

First, ensure your browser has microphone permission enabled (check the address bar). On Windows, verify the mic is set as the default input device in Sound Settings. On Mac, check System Preferences → Privacy → Microphone. Also try refreshing the page or using a different browser. External mics may need to be plugged in before opening the tool.

This tool records from your microphone input only. To record system audio or browser tabs, you would need a browser with "Share system audio" support (like Chrome's tab capture) or a virtual audio routing tool. Some operating systems allow loopback recording via sound settings.

This tool is web-based, requires no installation, works cross-platform, and exports directly to standard WAV format. Unlike phone apps, you can use it on any device with a browser. Files are saved locally to your computer — no cloud sync, no accounts, no subscriptions.

Yes — if your microphone or audio interface provides a stereo (2-channel) input, the WAV file will be exported as stereo. Most built-in laptop mics are mono, but external USB audio interfaces and stereo mics will produce multi-channel recordings automatically.
