WAV to MP3 converter
Make a small MP3 from a WAV master, a bounce or a recording. Pick the bitrate, keep or change the sample rate, and download the file. The conversion runs in your browser, so nothing is uploaded and there is no queue.

How it works
Drop the WAV on the page. Your browser reads the PCM audio, this page resamples or mixes it if you asked for that, and an MP3 encoder running in a background thread writes the file. The result is saved from your own device.
Choose the bitrate
320 kbps is the best MP3 can do and the right choice for a master you will share with musicians or upload to a platform that accepts MP3. 192 kbps is transparent for most listeners and half the size. 128 kbps suits speech and demos. A 4-minute track is about 10 MB at 320 kbps, 6 MB at 192 kbps and 4 MB at 128 kbps.
Sample rate and channels
The MP3 keeps the WAV's sample rate by default. MP3 stops at 48000 Hz, so a 88200 Hz or 96000 Hz WAV is resampled to 48000 Hz; pick 44100 Hz if the file is going to a CD-based workflow. Mono halves the size for voice recordings; a stereo WAV stays stereo unless you mix it down.
Keep the WAV
MP3 is for sharing and listening. Keep the WAV as the master, because the detail MP3 removes cannot be recovered from the MP3 later. If you still need to master the track, do that on the WAV first and convert the finished master.
From the label's own toolbox
BeatRootRaga is an independent label. Every release starts as a WAV master and ends up as an MP3 for the people who need a quick listen, so this converter is used in the label's own work and is online for anyone.

All guidesRaga Yaman (Kalyani)
Yaman is a seven-note Hindustani raga, a melodic framework, with a raised fourth; Kalyani shares its scale but uses different phrasing and ornaments. Traditionally associated with evening, Yaman can sound serene or devotional; hear its character through Ni Re Ga, starting below Sa, the home note.
Thaat and melakarta explained
A thaat in Hindustani music and a melakarta in Carnatic music are seven-note parent scales used to organise ragas, the melodic frameworks musicians perform. Hindustani music uses 10 practical categories, while Carnatic music uses 72 allowed scale combinations; these help identify note relationships, not a raga’s phrases or character.
Raga vs scale: what Western musicians get wrong
A raga adds rules for movement, emphasis, identifying phrases and ornamentation to a scale or mode, a scale with a home note. Producers lose its identity when they treat it as a note list, ignore its tuning and phrasing, or let changing chords reshape the melody’s meaning.
Raga Kirwani (Keeravani)
Kirwani is a raga, a musical framework, using C D Eb F G Ab B when Sa, its home note, is C. Heard in concerts, light classical music and film scores, it often suggests longing; listen for Ab rising to B, then C.
Raga Hamsadhwani
Hamsadhwani is a five-note raga from the Carnatic tradition, using Sa, Re, Ga, Pa and Ni, or C D E G B with Sa as C. It often opens Carnatic concerts; hear its bright, devotional character by playing the notes over C and G, noticing B resolving to C.
Raga Charukeshi (Charukesi)
Charukeshi comes from Carnatic music and uses Sa, Re, Ga, Ma, Pa, lowered Dha and lowered Ni. Heard in concerts, light music and film scores, its bittersweet character is clearest in the descent from lowered Ni through lowered Dha to Pa.
Questions people ask
Which bitrate should I use for music?
320 kbps if size does not matter, 192 kbps as a good everyday choice. Below 128 kbps the loss becomes audible on music, though speech is fine at 64 to 96 kbps.
Does a 24-bit WAV convert?
Yes. 16-bit, 24-bit and 32-bit float WAV files all convert; the bit depth is not part of an MP3, only the sample rate and bitrate are.
Why is 96000 Hz not offered for MP3?
The MP3 format goes up to 48000 Hz. A 96000 Hz WAV is resampled to 48000 Hz, which is above what any MP3 bitrate can carry anyway.
Is the WAV to MP3 converter free, and is my file uploaded?
Free, no account, no watermark, and nothing is uploaded. The file is encoded inside your browser.
Does the MP3 keep the metadata?
No. Titles, artist names and artwork are not copied. Add them in your player or tag editor after downloading.
