Voice Recorder guide

How to record audio on a computer (clearly)

Open a recorder (your computer's built-in app or one in the browser), choose your microphone, and say a few words to check the level: loud enough to move the meter well, never touching the top. Then sit close to the mic in a quiet room, record, and save the file as M4A for listening or WAV for editing.

What to record with

Every computer can record audio without extra software. The built-in apps are fine for a quick memo. A browser recorder works the same on every computer and adds a few things that help with longer recordings.

Ways to record audio on a computer
Computer	Built-in option	Good to know
Windows 11	Sound Recorder	Microphone only. Can save as M4A, MP3, WAV and more.
Mac	Voice Memos, or QuickTime Player (File › New Audio Recording)	Voice Memos saves M4A and syncs with iCloud if you use it.
Chromebook	Recorder app (ChromeOS 130 and later)	Can transcribe speech on the device.
Any of them	A browser recorder, like Voice Recorder	Level meter, bookmarks, trim, 0.5x to 2x playback, nothing uploaded.

No transcription hereVoice Recorder records and plays back audio; it doesn't turn speech into text. If a transcript is what you need, pick a tool built for that.

How to record, step by step

Choose the microphone. A headset or USB mic beats the laptop's built-in one. In Voice Recorder, pick it with the microphone button next to Record.
Allow access. The browser asks once for permission to use the microphone. If you said no by mistake, allow it again in the address bar's site settings.
Check the level. Speak as you will when recording and watch the meter. Voice Recorder's first-run check tells you "a bit quiet: move closer" or "too loud: move back a little".
Record. Press the red button. Pause and resume if you need a break; it stays one recording.
Mark moments. Tap the flag to bookmark something you'll want to find again.
Name and keep it. Give it a name you'll search for, trim the dead air at the start and end, and share or save a copy you want to keep.

Microphone placement

Distance matters more than the microphone. The closer the mic is to the voice, the louder the voice is compared with the room, and the less echo and noise you hear.

Close, but not too close. About a hand's width to a forearm's length (10 to 30 cm) for a USB or headset mic. Slightly off to the side cuts "p" and "b" pops.
Laptop mic? Sit squarely in front of the laptop and keep the distance steady.
Away from noise. Fans, keyboards and the laptop itself are loud to a microphone. Don't type near it while recording.
A soft room. Curtains, a sofa and a rug absorb echo. A small furnished room sounds better than a bare kitchen.
Record a few seconds of silence first. It shows you how much background noise there is before it matters.

Music or instruments?Browsers apply echo and noise reduction meant for speech. For music, turn off Voice clean-up in Voice Recorder's settings so the browser doesn't squash the sound.

Getting the level right

Digital audio has a hard ceiling. Anything louder than the top of the meter (0 dB) is cut off, or clipped, and sounds harsh in a way you can't fix afterwards. Too quiet is better than too loud, but very quiet recordings are full of hiss when you turn them up.

Aim for normal speech to sit in the upper middle of the meter, with the loudest moments still well short of the top. If you laugh or lean in, the peaks should still have room.

Worked example

You're recording an interview across a table with one laptop. Your voice hits the top of the meter and your guest barely moves it.

Turn the laptop so the mic points between you, then move it closer to your guest until your two voices move the meter about the same. Do a 10-second test, play it back, and only then start.

M4A, WebM or WAV?

Recorders save a compressed file by default because it is small. Which one you get depends on the browser: Voice Recorder records M4A in Safari and WebM in Chrome, Edge and Firefox, and can save any recording as a WAV.

Audio formats compared
Format	Size	Best for
M4A (AAC)	Small, about 1 MB a minute on High quality	Voice notes and lectures. Plays on almost everything.
WebM (Opus)	Small, similar to M4A	Speech in Chrome, Edge and Firefox. Some phones and editors can't open it.
WAV	Large, uncompressed (often 5 MB a minute or more)	Editing in another program, or an archive copy.

Converting a compressed file to WAV doesn't add quality back. It just makes a file that every editor accepts.

Recording a lecture

Ask first. Many universities have a recording policy, and some lecturers say no. Disability support plans often include permission to record.
Sit near the front, close to the speaker or a loudspeaker, away from the projector fan.
Plug in. A long recording keeps the computer busy. Voice Recorder keeps the screen on while it records, and if the page closes by accident it puts the recording back together on your next visit.
Bookmark as you go. Tap the flag when the lecturer says "this will be in the exam", then add a note. Later you can search bookmark notes and jump straight there.
Review at speed. Playing back at 1.5x keeps the voice's natural pitch and saves a third of the time.

Free recordings are up to 10 minutesIn Voice Recorder, each free recording stops at 10 minutes, with a warning at 9. That suits memos and short interviews. For full lectures, Voice Recorder Pro removes the limit, or use your computer's built-in recorder.

Keeping recordings private

Many free online recorders upload your audio to a server to process it. Voice Recorder doesn't: recordings are made and stored in your browser on that computer. The flip side is that clearing your browser's site data deletes them, so share or save the important ones somewhere you back up.

Common mistakes

Recording the wrong mic. A webcam mic across the room is often chosen by default. Check before you start.
Clipping. A meter that hits the top means distorted audio. Move back or turn the input down.
Typing notes on the same laptop. The microphone hears every key. Use a separate notebook or bookmarks.
No test recording. Ten seconds of checking saves an hour-long recording you can't use.
Keeping the only copy in one place. Save important recordings as files and back them up.

Questions

Can I record the sound coming from my computer?

Not with a microphone recorder: Voice Recorder, Windows Sound Recorder and Voice Memos record a microphone. To capture a video call or a browser tab's sound, use a screen recorder that can include tab or system audio, such as Yuzool's Screen Recorder in Chrome or Edge, and only record people with their permission.

Does Voice Recorder transcribe recordings?

No. It records, bookmarks, trims and plays back audio, but it doesn't turn speech into text. If you need a transcript, use a separate transcription tool, or the Recorder app built into recent Chromebooks, which transcribes on the device.

Which format should I save in, M4A or WAV?

Use M4A (or WebM) for voice notes, lectures and anything you just want to listen to: the files are small and sound fine. Use WAV when you will edit the audio in another program or need an uncompressed copy, and accept that it is many times larger.

How long can I record for?

In Voice Recorder, free recordings run up to 10 minutes each, with a reminder at 9 minutes, and you can make as many as you like. Voice Recorder Pro removes the limit for long lectures and interviews. Built-in recorders are usually limited only by free disk space.

Where are my recordings saved?

In Voice Recorder, recordings are kept in your browser's storage on that computer and are never uploaded. Clearing the browser's site data deletes them, so share or save the ones you want to keep as files.

Is it legal to record a lecture or conversation?

It depends on where you are and on the rules of your school or workplace. Many universities have a lecture recording policy, and some places require everyone's consent to record a conversation. Ask first; this is general information, not legal advice.
