To record audio on a computer, open a recorder, choose your microphone, check the level, and press record. You don't need to install anything: Windows has Sound Recorder, Macs have QuickTime Player and Voice Memos, and any computer can record in a browser. Recording the computer's own sound (a call, a video, a game) is different and needs one of the methods near the end.

Here are the five free options, the format to save for each job, settings that give clean audio, and fixes for silent or quiet recordings.
The short answer
Quickest on any computer: open QuickVeed's free Voice Recorder in Chrome, Edge, Firefox or Safari, allow the microphone, record (up to 60 minutes), and download M4A, WebM or WAV. On Windows, use Sound Recorder; on a Mac, QuickTime Player (File > New Audio Recording; High is 44,100 Hz AAC) or Voice Memos; for editing, Audacity. Keep peaks around -12 to -6 dB, record 10 to 20 cm from the mic, and save WAV if you'll edit.
Key takeaways
- Built-in: Sound Recorder on Windows, QuickTime Player and Voice Memos on a Mac.
- In a browser: no install, works on Chromebooks too; QuickVeed's recorder saves M4A or WebM, or WAV for editing.
- Save WAV for editing and M4A/MP3 for sharing; a WAV minute is about 10 MB, an M4A minute about 1 MB.
- Microphone permissions are the most common reason for a silent recording.
- Recording the computer's own sound needs a different route: a screen recorder with system audio, or a virtual audio device.
How do you record audio on a computer for free?
You record audio for free with a browser recorder or the app built into your computer. The browser route works the same on every system:
- Plug in your microphone (or use the built-in one) and open QuickVeed's free voice recorder.
- Click Start recording and allow the microphone when the browser asks.
- Watch the live waveform and level meter while you speak; pause and resume if you need to.
- Click Stop, play it back, and download it as M4A (Safari and Chrome) or WebM, or as WAV for an audio editor.
Noise and echo reduction is on by default, recordings can be up to 60 minutes, and the tool is free, runs in your browser and never uploads anything. It records at 128 kbps at your microphone's own sample rate. Before a long session, check the input with the free mic test; how to test a microphone explains what a good level looks like.
How do you record audio on Windows?
You record audio on Windows 11 with the built-in Sound Recorder app (called Voice Recorder on some Windows 10 PCs). Open Start, type Sound Recorder, choose the microphone, and press Record (or Ctrl+R). PCWorld's guide to Windows 11's recording tools lists the formats you can choose in the app's settings: M4A, MP3, WMA, FLAC and WAV, with quality options from medium to best.
| Windows option | Best for | Notes |
|---|---|---|
| Sound Recorder | Quick voice notes and voiceovers | Pick the format in settings; microphone input |
| Browser recorder | Same, with a level meter and WAV export | No install; any browser |
| Audacity (free) | Recording you'll edit, multitrack | Choose the input device and 48 kHz or 44.1 kHz |
| Snipping Tool (Win + Shift + R) | Screen plus voice | Records video; extract the audio afterwards |
If Windows records silence, open Settings > Privacy & security > Microphone and make sure microphone access is on for the app (and for desktop apps, if you're using Audacity).
How do you record audio on a Mac?
You record audio on a Mac with QuickTime Player or Voice Memos, both built in. In QuickTime Player, choose File > New Audio Recording, pick the microphone and quality from the menu next to the record button, click record, then save. Apple's QuickTime guide says High quality records 44,100 Hz AAC audio and Maximum records uncompressed 24-bit AIFF-C, which uses much more space.
| Mac option | Format | Best for |
|---|---|---|
| QuickTime Player, High | AAC, 44.1 kHz | Voice notes and voiceovers to share |
| QuickTime Player, Maximum | 24-bit uncompressed AIFF-C | Recordings you'll edit heavily |
| Voice Memos | M4A | Quick recordings, synced to iPhone |
| GarageBand or Audacity | Your choice | Multitrack, music, editing |
On a Mac, permission is per app: System Settings > Privacy & Security > Microphone must list your browser or recording app as allowed. If you're recording for a video, note that QuickTime records at 44.1 kHz while video projects usually use 48 kHz; 44.1 kHz vs 48 kHz explains why it matters.
How do you record audio on a Chromebook?
You record audio on a Chromebook in the browser: open the free voice recorder in Chrome, allow the microphone, and record. Chromebook's built-in screen recorder can also capture your voice with video; Chromebook Help describes turning on the microphone in the capture bar's settings. For audio only, the browser recorder is simpler and gives you WAV or a compact file directly.
Which audio format should you save?
Save WAV if you'll edit the recording and M4A (AAC) or MP3 if you'll just share or upload it:
| Format | Size per minute (stereo) | Use it for |
|---|---|---|
| WAV, 16-bit, 48 kHz | about 11.5 MB | Editing, voiceovers going into a video |
| M4A (AAC), 128 kbps | about 1 MB | Sharing, podcasts, messages |
| MP3, 128 kbps | about 1 MB | Anything that needs MP3 specifically |
| WebM (Opus) | about 1 MB | Browser recordings; convert for editors that won't open it |
| FLAC | about half of WAV | Lossless archive |
Need to cut the start or end? The free audio cutter trims M4A, MP3, WAV and WebM in your browser; how to cut audio shows the steps. If the recording is too quiet, the free audio volume booster raises it without clipping; how to make audio louder has the loudness targets.
How do you record the sound playing on your computer?
You record the computer's own sound (system audio) with a recorder that can capture it, because ordinary voice recorders only listen to the microphone. Options:
- Browser screen recorder: QuickVeed's free screen recorder can mix your microphone with a tab's sound, or with system sound when you share the whole screen and the browser offers it. Extract the audio afterwards with the free audio extractor.
- Mac: Apple says the Screenshot toolbar (Shift-Command-5) can include system audio in screen recordings on macOS 27 or later. On older versions, a free virtual audio device such as BlackHole routes system sound into a recorder.
- Windows: Audacity can record from a loopback (WASAPI) input; Snipping Tool's screen recording can include system audio.
If a recording comes out silent, why a screen recording has no sound walks through every case. Only record calls and other people with their permission.
How do you get better sound when recording on a computer?
You get better sound by fixing the room and the distance before touching any settings:
- Record in a small room with soft things (curtains, a sofa, clothes); avoid bare walls and kitchens.
- Keep the mic 10 to 20 cm from your mouth, slightly off to the side to avoid popping sounds.
- Set the input level so your loudest words peak around -12 to -6 dB on the meter, never at 0.
- Turn off fans, notifications and anything humming; record a few seconds of silence to check.
- Use headphones if you're listening to anything while recording, so the mic doesn't pick it up.
Don't want to record your own voice at all? QuickVeed's AI voice generator reads a script in one of 9 voice models, from 7 credits per 1,000 characters. How to add a voiceover to a video covers both routes.
If you need the screen as well as your voice, how to screen record on Windows, Mac, iPhone and Android covers every built-in recorder.
