Pitch changer
Move a song into a key you can sing, drop a backing track to your Sa, or shift a sample. Choose the semitones, keep the tempo or let the speed change with the pitch, preview 20 seconds, and save. Everything runs in your browser.

How it works
Drop the file on the page and your browser decodes it. Set the shift in semitones, from an octave down to an octave up, and choose whether the tempo stays the same. Preview plays 20 seconds from the middle of the file with the shift applied. Save encodes the whole file as MP3 or WAV in a background thread.
Keep the tempo or change the speed
Keeping the tempo uses a phase vocoder: the audio is stretched in time by the pitch ratio and then resampled, so the key moves and the length stays. Changing speed with the pitch is what a tape machine or a turntable does: two semitones up makes the file about twelve percent shorter and faster. The tape setting sounds cleaner but changes the tempo.
Finding the right shift
One semitone is the distance between two adjacent keys on a piano. To move a song into your range, find the key you want to sing in, count the semitones from the original key, and shift by that many. The online tuner shows the note you are singing and its sargam name, which makes the count quick.
What to expect from the sound
Within three or four semitones, voice and melody instruments shift cleanly. Drums and other sharp attacks can smear a little when the tempo is kept, and a full octave in either direction sounds processed on any tool. For practice tracks and reference versions it is more than good enough; for a release, re-record in the new key.
From the label's own toolbox
BeatRootRaga is an independent label, and the label's singers use this to try a song in another key before a session. Pair it with the karaoke maker: remove the vocal, then shift the instrumental to your key and practise over it.

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.
What is a raga? A plain-language guide for listeners
A raga is a melodic framework in Indian classical music for creating pieces and inventing melody during performance. Listen for four things: which notes appear, how the melody moves, where the musician lingers, and which short phrases return.
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 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.
Raga Bhoop (Mohanam)
Bhoop, or Bhoopali, is a raga (melodic framework) using Sa, Re, Ga, Pa and Dha; Mohanam shares its notes, but uses Carnatic phrasing and ornaments. An evening raga with a calm, devotional mood, Bhoop is often taught early; hear its character through Ga Re Sa and Dha Pa Ga.
Questions people ask
Is the BeatRootRaga pitch changer free, and is my file uploaded?
Free, no account, and nothing is uploaded. The file is decoded, shifted and encoded inside your browser.
Can the pitch changer change the key of a song without changing the speed?
Yes. Choose Keep the tempo. The length of the file stays exactly the same; only the pitch moves.
How many semitones can I shift a song?
Up to 12 semitones, an octave, in either direction. Most key changes for singing are within five semitones, where the sound stays clean.
Why does the shifted song sound a little blurred?
Keeping the tempo while changing the pitch means stretching the audio, and sharp sounds such as drum hits spread slightly in the process. Smaller shifts smear less. The tape setting avoids it but changes the speed too.
Can I shift the pitch of a karaoke track or a backing track?
Yes, and that is the most common use: make the karaoke track with the karaoke maker, then shift it to your key here and save it for practice.
