Audio Recorder

What Audio Recorder helps you do

Record your microphone in the browser without installing anything. A live level meter confirms your input, you can pause and resume while you work, then preview and download the audio. Recording stays on your device, so a voice note or interview draft never has to be uploaded to a service.

Recording uses the browser's MediaRecorder API and stays on your device. Your microphone audio is not uploaded to Haivix servers.

How it works

The browser's getUserMedia API opens the selected microphone, and MediaRecorder encodes the stream into an audio file. The level meter reads the live signal so you can catch a muted or quiet input before the take ends. The recording is held in the page and downloaded directly; no audio is sent to a server.

How to use Audio Recorder

1. Choose a microphone if you have more than one, then select Start recording.
2. Speak and watch the level meter; pause and resume as needed.
3. Select Stop, preview the clip, and download the audio.
4. Convert the file if the destination requires MP3 or a smaller size.

When to use it

• Record a voice note, memo, or quick interview without an app.
• Capture narration for a video or presentation.
• Check that your microphone works before a call or recording.
• Draft a podcast segment or a spoken outline.
• Record a pronunciation or language practice clip.
• Keep a spoken record of a meeting when notes are not practical.
• Capture a pronunciation or language-learning clip for later review.

When not to use it

• Do not use it to record system or tab audio; it captures the microphone only.
• Do not record a conversation without the other person's consent.
• Do not use it as a multitrack editor or a noise-removal tool.

Example

A product manager records a three-minute voice note explaining a change, pauses once to check a date, and downloads the WebM. The clip is attached to the task; the engineer can listen at 1.5x instead of reading a long message.

What you can do with Audio Recorder

• Choose the microphone when more than one input is available.
• Watch a live level meter while recording.
• Pause and resume without starting a new file.
• Preview the clip before downloading it.
• Download as WebM (Opus), or another format the browser supports.
• Keep the recording local to the browser.

Example: record a voice note for a colleague

Select the right microphone, start recording, and say a short test sentence while watching the meter. If the level barely moves, choose another input or move closer before recording the real note.

Pause when you need to check a detail, then resume and finish. Stop, preview the clip, and download it with a descriptive filename.

If the file needs to be smaller or more compatible, convert it to MP3 with the audio converter before sending it.

What to know before you start

• Microphone recording needs a current desktop browser and permission.
• Recordings save as WebM (Opus) in most browsers; the format follows browser support.
• This records your microphone, not system or tab audio.
• There is no trimming, noise removal or multitrack mixing in the recorder.
• Long recordings are held in memory and can be large.

Common mistakes

• Recording with the wrong input device selected.
• Ignoring a level meter that barely moves until the take is over.
• Closing the tab before downloading the clip.
• Assuming the browser will produce MP3; it usually produces WebM/Opus.
• Recording a sensitive conversation in a shared space.
• Recording next to a fan or air conditioner and expecting clean audio without a pass in an editor.
• Recording a clip that will be transcribed without checking the microphone level first.

Troubleshooting

If the meter stays flat, check the mic permission, the selected device, and the system input level. A muted hardware switch is a common cause.

If the recording is noisy, move away from fans or use a headset. The recorder does not remove background noise.

If an app will not open the WebM file, convert it to MP3 or WAV with the audio converter.

If the browser does not offer a device you expect, close other apps that may be holding the microphone and reload the page.

If the download is empty, the recording may have been stopped before any audio arrived. Record a few seconds and try again.

If the recording is much quieter than expected, check the input gain in the operating system's sound settings, not just the browser permission.
