🎙️ Audio Recorder
A browser-based audio recorder that captures microphone input and exports as WAV or compressed audio — no installs, no sign-up, no ads. The tool displays a real-time waveform while recording so you can visually monitor audio levels and catch clipping before it ruins a take. Choose lossless WAV for editing or compressed audio for sharing, both generated entirely in your browser. Recordings never leave your device. Supports up to 30 minutes or 500 MB per session.

📋 When to Use an Online Audio Recorder
A browser-based audio recorder is the fastest way to capture voice memos, practice recordings, or quick ideas without launching desktop software. It's ideal for podcasters who want to record a test take before committing to a DAW session, for journalists capturing an interview on a borrowed computer, for musicians reviewing practice sessions, and for anyone who needs to record a voice note without hunting for their phone's recorder app. Because everything runs in your browser, there's zero setup — just open the page, allow the microphone, and start recording.
A couple of honest limits. Your browser's MediaRecorder API captures audio at the quality your microphone provides — this tool won't magically improve a noisy laptop mic. For professional-grade recording, a dedicated USB microphone and a DAW like Audacity or GarageBand will give better results. The 30-minute / 500 MB cap exists to prevent browser memory issues with very long recordings; if you need longer sessions, desktop software is more appropriate.
⚙️ How the Audio Recorder Works
This tool uses the MediaRecorder API, which every modern browser supports for capturing microphone input. When you grant microphone permission, the browser creates a MediaStream from your mic. A connected AnalyserNode from the Web Audio API samples the audio in real time and draws the waveform you see on screen — this isn't just eye candy; it confirms your mic is working and lets you spot clipping (when the waveform hits the top or bottom of the display).
When you press Stop, the tool processes your recording in two formats. WAV is generated by decoding the raw audio chunks into an AudioBuffer and writing the PCM samples with a standard WAV header — this gives you a lossless file perfect for editing in Audacity, Premiere, or any DAW. Compressed audio is your browser's native format (typically Opus in a WebM container), which is about 10x smaller and ideal for sharing via email or messaging apps. Both files are created entirely in your browser memory — at no point is your audio uploaded to any server.
The 30-minute / 500 MB cap is a technical safeguard. MediaRecorder stores chunks in browser memory, and very long recordings can cause tab crashes or memory exhaustion. You can start a new recording immediately after finishing one — there's no daily limit and no account required.
How to Use the Audio Recorder
- Grant microphone permission — When you open the tool, your browser will show a permission prompt. Click "Allow" to enable recording. If you accidentally denied it, click the lock/camera icon in your address bar to reset the permission.
- Click the Record button — Press the red Record button (⏺) to start capturing audio. You'll immediately see a waveform on screen, confirming your microphone is working. The timer starts counting up.
- Monitor your levels — Watch the waveform as you speak or play. If the waveform consistently hits the top or bottom edges, you're clipping — try moving farther from the mic or lowering your input volume in your system settings.
- Stop and download — Click Stop when you're done. Download buttons appear: choose WAV for lossless quality (best for editing) or Compressed for a smaller file (best for sharing). You can download both from the same recording.
Frequently Asked Questions
How can I record audio on my computer without downloading any software?
Open the Audio Recorder tool in any modern browser (Chrome, Edge, Firefox, or Safari), grant microphone permission when prompted, and click the Record button. Your browser's built-in MediaRecorder API handles the capture — no installs, no extensions, no admin rights needed. When you're done, download as WAV (lossless, best for editing) or compressed audio (smaller, best for sharing). Everything runs locally on your device.
Should I record in WAV or compressed — which is better?
WAV is uncompressed and lossless — choose it when you plan to edit the audio later (podcast production, music practice review, interview transcription) because editing compressed audio degrades quality further. Compressed audio (typically Opus in WebM) is about 10x smaller — choose it for quick sharing via email, messaging apps, or uploading to cloud storage. The tool lets you download both formats from the same recording, so you don't have to decide upfront.
Why won't my browser let me use the microphone?
Three common causes: (1) You denied the microphone permission popup — click the lock/camera icon in your address bar to reset it. (2) Your browser requires HTTPS for microphone access — all ToolStand pages are HTTPS. (3) On macOS, check System Preferences → Security & Privacy → Microphone and ensure your browser is checked. If using Firefox, note that it requires explicit media.navigator.permission.disabled to be false in about:config.
Is it really free? How long can I record?
Yes, completely free with no hidden limits. You can record up to 30 minutes or 500 MB per session — whichever comes first. This is a technical safeguard to prevent browser memory exhaustion, not a monetization gate. There is no daily cap, no premium tier, no "remove ads" upsell, and no account required. Each recording session runs independently — finish one and start another immediately.
Are my recordings private? Where is the audio stored?
All audio processing happens inside your browser using the MediaRecorder API and local JavaScript encoding — nothing is uploaded to any server. Your recordings exist only in your browser's memory during the session and as a downloaded file afterward. There is no cloud storage, no account to track you, and no analytics tied to your recordings. Once you close the tab, the in-memory audio is gone.
Can I record my computer's system audio, not just the microphone?
No — browser-based recorders can only capture microphone input via getUserMedia. Recording system audio (what you hear from your speakers) requires OS-level audio routing (like Stereo Mix on Windows, BlackHole on macOS, or PulseAudio on Linux) or desktop recording software like OBS. For recording a video call or streaming audio within the same browser tab, use the browser's built-in tab-capture which is separate from this tool's microphone recorder.
