Audio Recorder

About Audio Recorder

This online audio recorder captures audio directly from your microphone in your browser with stereo, up to 48 kHz, lossless 16-bit WAV. No software installation needed. Perfect for podcasts, music practice, interviews, voiceovers, or any audio content. After you stop, it runs a real EBU R128 / ITU-R BS.1770 analysis and reports Integrated LUFS and true-peak (dBTP) with a streaming/broadcast compliance verdict. Choose WAV (lossless) or WebM (Opus). All recording and analysis happen locally for complete privacy. See also our Audio Converter and Audio Trimmer.

What can I record with this tool?

Anything your microphone can capture: voice memos, podcasts, interviews, singing, musical instruments, lectures, meetings, audio notes, voiceovers, or any other sound.

What formats can I record in?

WAV (lossless 16-bit PCM, high quality, larger files) or WebM with Opus codec (compressed, good quality, smaller files). WAV is best for editing and professional use. WebM is great for quick recordings and sharing.

What record level (dBFS) should I aim for?

Target peaks around -12 to -6 dBFS and keep headroom so you never hit 0 dBFS, which clips. The live input meter is now a real peak/dBFS meter: stay mostly green, let yellow flash on loud moments, and avoid red. Clipping is permanent distortion that cannot be repaired afterward.

What is the LUFS and true-peak analysis for?

After recording, the tool measures Integrated Loudness in LUFS (EBU R128 / ITU-R BS.1770 with K-weighting and gating) and true peak in dBTP (4x oversampled). Aim for about -14 LUFS for streaming (Spotify, YouTube, Apple Music) or -23 LUFS for EBU R128 broadcast, with true peak at or below -1 dBTP. The verdict badge tells you on the spot whether to keep the take or re-record.

Should I disable noise suppression and auto gain for music?

Yes. For music, forensic, or any reference recording, turn OFF noise suppression and echo cancellation. These processors and browser auto gain control alter the signal, pump levels, and make loudness measurements unreliable. Leave them on only for casual speech or calls where intelligibility matters more than fidelity.

What do the sample rate options mean?

16 kHz: Low quality, voice only, smallest files. 22.05 kHz: Voice quality, good for podcasts. 44.1 kHz: CD quality, recommended for most uses. 48 kHz: Professional quality, best for music and production.

Do I need to install anything?

No! Everything works directly in your browser. Just allow microphone access when prompted and start recording.

Is my recording private?

Absolutely! All recording happens locally in your browser. Audio is never uploaded to any server. You have complete control over your recordings.

Can I pause and resume recording?

Yes! Click 'Pause' to temporarily stop recording, then 'Resume' to continue. This lets you take breaks without creating multiple files.

What does the volume meter show?

The volume meter shows your microphone input peak level in real time as a dBFS reading. Green is good, yellow is getting loud, red means you are near clipping (0 dBFS). Adjust your microphone position or system volume to stay mostly in the green zone and keep peaks around -12 to -6 dBFS.

Why can't I select my microphone?

You need to grant microphone permission first. After you click 'Start Recording' and allow access, refresh the page and your microphones will appear in the dropdown.

How long can I record?

There's no hard time limit, but very long recordings (over 30 minutes) may use significant memory. For long recordings, consider recording in segments and joining them later.

Can I record system audio (computer sounds)?

This tool records from your microphone. To record system audio, you need different methods depending on your OS (like Stereo Mix on Windows, or Soundflower on Mac).

What if my recording sounds bad?

Check: 1) Microphone is connected properly, 2) Correct microphone is selected, 3) Volume meter shows activity (not too quiet or loud), 4) Use higher sample rate (44.1 or 48 kHz), 5) Reduce background noise, 6) Position microphone correctly.

Can I edit the recording after?

This tool only records. For editing, download your recording and use our other audio tools (Audio Trimmer, Audio Fade, etc.) or import into an audio editor.
