Free online audio tools
Two tools that independent musicians use every week: an AI mastering engine that gets a mix ready for release, and a stem splitter that takes a song apart into vocals and instruments. Both run online, both let you hear the result before you commit, and neither needs a subscription.
Online audio mastering
Upload a mix, choose a genre preset, set a loudness target in LUFS and preview the master before you download it as a WAV. Built for singles going to Spotify, Apple Music and YouTube.
- Genre presets and adjustable parameters
- LUFS loudness targeting with true-peak limiting
- Instant preview before download
- WAV output ready for streaming platforms
- Free, no subscription
For: Independent artists, producers and home studios who need a release-ready master without a studio booking.
AI stem splitter
Separate any song into vocals and instrumental, or into vocals, drums, bass and other. Hear a 21-second preview of the separation without signing up, then process the full track in the background.
- 21-second preview without an account
- 2-stem and 4-stem separation
- MP3, WAV, FLAC and AIFF up to 100 MB
- Stems as 44.1 kHz stereo WAV files
- Runs in the background; results in your dashboard
For: Singers making covers and practice tracks, producers remixing, DJs and teachers isolating parts.
How the tools work
Upload a file, hear a preview, then process the full track. Mastering returns a WAV master at the loudness you choose; stem separation returns each stem as its own WAV in your dashboard. Files are processed on our servers and you keep your rights to your own recordings.
Made by a label, for musicians
BeatRootRaga is an independent label that records ghazals, Indian classical and film-song covers. The tools grew out of the label's own work: mastering singles for streaming and separating reference tracks so singers can practise. That is why they favour natural dynamics over loudness for its own sake.
Learn while you work
The Learn section explains the ideas behind the tools in plain language: what LUFS means, how a mastering chain is ordered, how to mix a vocal, and how to make a female version cover from a separated reference.

All guidesMastering vocal-led acoustic Indian tracks
Aim around minus 14 LUFS, a unit measuring loudness, with true peak, the maximum reconstructed signal level, at or below minus 1 dBTP (decibels true peak). Use gentle processing and preserve dynamic range, the contrast between quiet and loud passages, to keep the voice forward, the drone steady and vocal ornaments expressive.
Bansuri: the bamboo flute explained
The bansuri is North India's side-blown flute, made from one hollow, seasoned length of bamboo with a blowing hole and six or seven finger holes. Fingers and breath change its notes without keys; listen for slides between notes, breath-shaped phrases and returns to Sa, the home note.
Raga 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.
Mukhda and antara: how a film song is built
In a typical Hindi film song, the mukhda is the returning opening section, while an antara is a verse with new words and melody. This pattern comes from Hindustani classical music; listen for the verse climbing higher, then leading back to the opening tune.
Tuning to shruti: using a tanpura drone in a mix
Set the project’s pitch from the singer’s shruti, their chosen Sa or home note, after checking the song’s lowest and highest phrases. Tune the tanpura, a plucked instrument providing a drone or continuous pitch reference, to that Sa and keep it beneath the voice throughout.
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.
Questions people ask
Are the BeatRootRaga audio tools really free?
Yes. Mastering a track and separating a song into stems are free, with no subscription. An account is only needed to keep results in your dashboard and to run full-length stem separations.
Do I need to install anything?
No. Both tools run in the browser on desktop and mobile. You upload a file, preview the result and download the output.
Which audio formats can I upload?
MP3, WAV, FLAC and AIFF. For mastering, upload the final mix with a few decibels of headroom rather than an already limited file.
What loudness should I master to for Spotify or Apple Music?
Around minus 14 LUFS integrated with true peaks at or below minus 1 dBTP suits streaming platforms, which turn louder tracks down. The mastering tool lets you set the target and preview it.
Can I use the stems commercially?
Separating a song does not change who owns the recording. Use stems only from music you own, have permission to use, or that is licensed for your purpose.
Which AI model does the stem splitter use?
Demucs, an open-source hybrid transformer model for music source separation. The preview and the full song use the same model.
