What is the Voice Recorder?
The Voice Recorder is a browser-based microphone capture tool. It uses the Web MediaRecorder API so you can record voice notes, solo podcast takes, language practice, or quick ideas without installing an app or creating an account. The recording stays in memory on your device until you download it — Sound Booster does not upload your audio to a server.
Click the large mic button to start. Your browser asks for microphone permission once; choose Allow. While you record you see a live level meter and a scrolling waveform so you know the signal is present. Click the mic again to pause and resume, then press Finish & save when the take is done. Optional start/end trim lets you cut silence before export.
Export is typically WAV (16-bit) so you can keep editing quality for Equalizer, Bass Booster, Trimmer, or Volume Booster on the same site. If you need a smaller file for sharing, convert the download with Audio Converter. The recorder works on desktop and mobile browsers that support getUserMedia and MediaRecorder (Chrome, Edge, Firefox, Safari with recent versions).
Typical uses include voice memos, dictation drafts, podcast intros, language practice, and capturing a melody idea. Because everything is local, it is suitable when you do not want a cloud recording service. Pair the export with Noise-friendly EQ or Normalize on the main booster if the room was quiet but the level is low.

Common use cases
Voice memos
Capture an idea from a laptop or phone — no app install, no cloud sync.
Podcast solo takes
Record the voice track, then EQ and normalize with the other tools on this site.
Language practice
Record yourself, play back, compare. Pause is useful for stop-and-think drills.
Demo ideas
Hum a melody or sing a hook, then send the file to Trimmer or Pitch Shifter.
Frequently asked questions
Is my voice uploaded?
No. Recording and export run in your browser, and the audio never leaves your device. The microphone stream is captured locally, kept in memory while you record, and saved only when you download it. Sound Booster does not need a server copy of your voice notes, interviews or practice takes for this tool to work.
Can I pause and resume?
Yes. Click the mic to pause, click again to resume. Finish & save produces one continuous file, so the pauses do not leave gaps or separate clips in the result. This is handy for scripted reads, where you want to stop and check notes without cutting the take apart later.
What is the maximum length?
No hard limit from us. Practical length depends on device memory, often 1–2 hours on a laptop. Phones and older computers may manage less, and the recording stays in memory until you download it. For very long sessions, record in several parts and save each one as you go.
Why is the level meter flat?
The mic may be muted, the wrong input selected, or permission denied. Check the input device list on the page, the microphone permission in your browser’s site settings, and the system volume or mute switch on a headset. If you use a USB or Bluetooth mic, reconnect it and reload the page.
What format is the download?
Default export is WAV (16-bit, lossless, same sample rate as capture), which is the best choice for further editing. The format menu also lets you pick an MP3 bitrate when you need a smaller file. You can also send the recording to the Audio Converter for other formats.
Can I choose which microphone to use?
Yes. The Input device menu lists the microphones your browser can see, so you can pick a USB mic, a headset or the built-in one. If a device does not appear, check that it is connected and that the browser has permission to use it, then reload the page. Switching input before you start recording avoids surprises.
How can I get a cleaner voice recording?
Record in a quiet room, keep the mic at a steady distance from your mouth, and watch the level meter so you do not clip on loud words. Soft furnishings reduce echo. After recording, use the optional trim to remove silence, and if the level is low, bring the file into the Volume Booster or Equalizer.
Does the Voice Recorder work on a phone?
It works in desktop and mobile browsers that support microphone access and MediaRecorder, such as recent versions of Chrome, Edge, Firefox and Safari. On a phone, allow the microphone prompt and keep the screen on and the tab in the foreground while recording. Some mobile browsers pause background tabs.
What happens if I close the tab before downloading?
The recording stays in memory on your device until you download it, so closing or refreshing the tab can lose it. Press Finish & save, choose your format and download the file as soon as the take is done. For important recordings, download after each section rather than waiting until the end.
What can I do with the recording after I save it?
You can send it directly to the Trimmer, Equalizer, Speed Changer, Pitch Shifter, Reverse tool or Volume Booster from the page. A common flow is to trim silence, clear up the tone with the Equalizer and then raise the level. Export from the final tool as WAV or convert to MP3 for sharing.
