How to Record Your Voice Online as WAV or MP3 (Free, No Upload)
You do not need an app to record clean audio. A modern browser can capture your microphone, and the Sayvoi voice recorder lets you choose the exact format your project asks for, then download everything in one ZIP file. The audio stays on your device.
Step by step
- Open the recorder and allow microphone access when the browser asks.
- Pick a preset (for example speech at 16 kHz mono) or set the format, sample rate, bit depth and channels yourself.
- Run the noise test: stay quiet for a few seconds and read the result. A noisy room is the most common reason recordings get rejected.
- Press record, speak, then press stop. Listen back and record again if needed.
- Download your takes as a single ZIP.
Which settings should you choose?
- WAV, 16 kHz, 16-bit, mono is a common choice for speech and wake-word data.
- WAV, 48 kHz, 24-bit is better when you need more headroom for editing.
- MP3 gives small files for sharing, but it is lossy; use WAV when the project asks for it.

Leading and trailing silence
You can keep a short margin before and after each take, since many specifications ask for it. See why silence at the start and end matters.
Your recordings are saved on your device
Takes are stored in your browser, so if you close the tab and return later you can continue where you stopped. Clearing your browser data or using a private window will remove them, so download your ZIP when you finish.
Record your voice as WAV or MP3 in your browser, free and private.
