MP4 to MP3 converter
Pull the audio out of a video and save it as an MP3. The conversion runs inside your browser, so the file is not uploaded anywhere and there is no queue: choose the file, pick the quality, download the result.
This page needs JavaScript for the tool itself. Open it in a browser to use it.
How it works
Drop an MP4, MOV or M4A file on the page. Your browser decodes its audio track, this page resamples and mixes it the way you asked, and an encoder running in a background thread writes the MP3. The finished file is offered for download from your own device. Nothing is sent to BeatRootRaga.
Choose the quality
Bitrate sets the size and quality of the MP3: 128 kbps is the usual choice for speech and casual listening, 192 kbps is a good default for music, 320 kbps is the best MP3 can do. Sample rate stays the same as the source unless you change it; 44100 Hz is the CD and streaming standard, 48000 Hz is what video uses. Mono mix-down halves the size and suits voice recordings.
WAV or AIFF instead of MP3
If the audio is going into an editor, a DAW or a mastering session, save it lossless: WAV at 16-bit, 24-bit or 32-bit float, or AIFF at 16-bit or 24-bit. There is no point converting a lossy source to a higher bit depth for quality, but it keeps an editor from re-encoding it again.
What the browser can read
Any file the browser itself can play: MP4 and MOV with an AAC or MP3 audio track, M4A, MP3, WAV, AIFF, FLAC and OGG. Very long recordings are limited by your device's memory, since the whole track is decoded before it is encoded; a phone manages a typical song or podcast episode, a laptop manages hours.
From the label's own toolbox
BeatRootRaga is an independent label. Converting reference tracks, video rushes and voice notes into files a session can use is daily work, and this page is the converter the label uses itself, put online for anyone. When the audio is a song you want to practise, the vocal remover and the stem splitter take it further.

All guidesTeentaal: the 16-beat cycle of Hindustani music
Teentaal is a 16-beat Hindustani rhythmic cycle counted in four groups of four, with claps on 1, 5 and 13, and a wave on 9. Its theka, or basic tabla stroke pattern, is dha dhin dhin dha | dha dhin dhin dha | dha tin tin ta | ta dhin dhin dha.
Taal for beginners: teentaal, keherwa and dadra with clap patterns
A taal is a repeating rhythmic cycle: count 16 beats for teentaal, eight for keherwa, and six for dadra. For teentaal, clap on 1, 5 and 13, wave on 9; for keherwa, clap on 1, wave on 5; for dadra, clap on 1, wave on 4.
Rupak: the 7-beat taal that starts on khali
Rupak is a taal, or repeating rhythmic cycle, with seven beats grouped 3 + 2 + 2. Its opening closed strokes make sam, the first beat, sound light; this beat is khali, marked by a wave, rather than tali, marked by a clap.
Keherwa: the 8-beat taal of film songs, bhajans and folk
Keherwa is an eight-beat taal, or repeating rhythmic cycle, arranged as 4 + 4. To recognise it, listen for two groups of four, a lighter second half, and the recurring drum pattern: dha ge na ti | na ka dhin na.
Jhaptaal: the 10-beat taal
Jhaptaal is a taal, a repeating rhythmic cycle, with ten beats. Its four vibhags, or divisions, follow 2 + 3 + 2 + 3, alternating two-beat and three-beat groups.
Ektaal: the 12-beat taal of khayal
Ektaal is a twelve-beat taal, or repeating rhythmic cycle, divided into six two-beat sections called vibhags. Its stretched beats let the tabla player elaborate the stroke pattern in vilambit (slow-tempo) bada khayal, the slow opening composition of a khayal performance.
Questions people ask
Is the BeatRootRaga MP4 to MP3 converter free?
Yes. There is no charge, no account and no watermark. The conversion happens in your browser, so there is no server cost to pass on.
Is my video uploaded when I convert MP4 to MP3 here?
No. The file is read by your browser on your device, converted there, and the result is saved from there. Close the tab and nothing remains anywhere.
Which MP3 bitrate should I choose when converting from MP4?
192 kbps is a good default for music, 128 kbps for speech, 320 kbps when size does not matter. A 4-minute track is about 6 MB at 192 kbps and 10 MB at 320 kbps.
Can the MP4 to MP3 converter keep the original sample rate and channels?
Yes, both default to the same as the source. You can also set any rate from 8000 Hz to 48000 Hz for MP3 (up to 96000 Hz for WAV and AIFF) and mix down to mono or force stereo.
Why did my MP4 fail to convert to MP3?
The browser could not decode it. Most often the video has no audio track, or the audio is in a codec the browser does not play (some MOV files use PCM or ALAC that only Safari reads). Try another browser, or export the audio from the source app first.
Is there a file size limit when converting MP4 to MP3 here?
No fixed limit. The whole track is decoded into memory before encoding, so the practical limit is your device: a phone handles a typical song or episode, a laptop handles hours of audio.
