01 — The tool
Record audio online with a microphone
The free Loudness.ai Audio Recorder captures sound from the microphone you choose. Use it for a voice note, narration take, lesson or spoken rehearsal. You can pause during a break, resume the same recording and stop when the take is complete.
Listen to the saved take before downloading, then choose MP3 or WAV, quality and sample rate. MP3 is useful for a smaller listening file; WAV suits further editing. The voice recorder can capture up to one hour. If a take needs trimming afterwards, open the Audio Cutter and keep only the passage you want.
02 — How it works
How to record voice online for free
Choose your microphone
Select the input you want to use and allow microphone access when your browser asks. Make a short test with the same distance and speaking volume you plan to use for the take.
Start, pause and resume
Start recording and watch the elapsed time and input level. Pause during breaks rather than filling the recording with a long wait. Resume when you are ready, then stop to finish the take.
Listen and download
Play the recording to check the opening, ending and loudest words. Choose MP3 or WAV, set quality and a useful filename, then export the audio for sharing or editing.
03 — Practical uses
Record voice notes, narration and spoken practice
Voice notes and ideas
Capture an explanation or reminder while it is fresh. Speak at a steady distance from the microphone. Give the download a descriptive name so you can find the recording later.
Video narration
Record a voiceover take separately from your video. Leave a brief pause between sentences to make editing easier. Use the Audio Enhancer if steady background noise distracts from the voice.
Lessons and speaking practice
Record a short explanation, pronunciation exercise or rehearsal. Listen back for pacing and clarity. For long gaps in a completed take, use the Silence Remover to shorten the pauses you no longer need.
04 — Frequently asked questions
Audio Recorder questions
Why does the voice recorder ask for microphone access?
The browser needs permission to capture your chosen audio input. Allow access for this recording session and check the selected microphone. If the input is wrong, choose the device you intended to use.
Does pausing create separate audio files?
Pause and resume continue the same take. Stopping finishes the recording so you can listen and export it. Use separate takes when you want independent files to arrange or compare later.
Can I download a microphone recording as MP3?
Yes. Choose MP3 in the export settings and select 128, 192 or 320 kbps. You can also save 16-bit or 24-bit WAV when you want an uncompressed file for editing.
How can I avoid a distorted voice recording?
Make a short test before the full take. Reduce your microphone's input level or move back if loud words sound harsh. Keep the recording distance consistent, and listen to the test rather than relying only on the level display.
