A Free Way to Build Practice Tracks for Every Student, Every Song

Assigning a student a new song usually means finding — or buying — a backing track for it, per student, per song. If the student (or the teacher) already has a video of the piece, that step goes away. OraKara turns it into a clean vocal track and a clean backing track directly, at no cost, for as many songs as it takes.

Prep a whole lesson list at once

Queue up every piece for the week — one student's whole set of assignments, or a full class's worth — and let OraKara work through the batch with a configurable concurrency limit, instead of processing one video at a time between lessons.

Isolate the part that matters for the lesson

Solo the vocal to check phrasing or pitch against the original recording, or mute it so the student practices against a clean accompaniment — same recording either way, just with the vocal exposed or removed depending on what that lesson is actually working on.

It's not a lesson-planning tool built for teachers specifically — it's a free, general-purpose practice track generator that happens to remove the single biggest recurring cost in assigning new material: finding or buying a backing track for it.
