Voice recorder — record mic to MP3 / WAV
Record from your mic and download as MP3 / WAV. Everything runs in your browser.
How to use
Click Record and grant microphone permission when prompted. Elapsed time and a live level meter are shown while recording. When you stop, the audio is encoded to MP3 and WAV in your browser and the download buttons appear. Bitrate, channels (mono / stereo) and echo cancellation / noise suppression / auto gain control toggles are available in the settings panel.
FAQ
- Is the recording uploaded anywhere?
- No. Capture and encoding both happen in your browser. The file only leaves your device if you download it and share it yourself.
- How long can I record?
- As long as your device has memory. Audio is buffered in RAM during the session, so multi-hour recordings may run out of memory.
- Does stereo always work?
- If the microphone only outputs mono, the tool falls back to mono automatically — it checks the actual channel count via MediaStreamTrack.getSettings().channelCount.
- Should I pick MP3 or WAV?
- Use MP3 for sharing (smaller file) and WAV for further editing (lossless).

BPM auto-detect — estimate the tempo of an audio file
Drop an audio file (MP3 / WAV / M4A / FLAC / OGG) and we estimate the BPM in-browser using a low-pass filter + peak picker + histogram. Great for finding the tempo of a DJ partner track, checking sample packs, matching dance / running cadence, or grabbing a source BPM before running bpm-time-stretch. Half-tempo and double-tempo candidates are also shown so you can override 4-on-the-floor misreads (60 vs. 120). Everything stays in your browser.
Audio channel merge — two mono files into a stereo L + R
Combine two mono audio files (MP3 / WAV / M4A / FLAC / OGG) into one stereo file. The first file becomes the left channel, the second becomes the right; we interleave them and output one stereo WAV / MP3. Useful for putting two-mic interview takes into a single L/R file, faking stereo from a mono source, or reversing audio-channel-split. When lengths differ, truncate to the shorter file or pad the shorter one with silence — your choice. Everything stays in your browser.
