Re-record, swap or add the part in your own session.

Number of songs, and a note on what changed and where in the song.

Upload the multitrack with the new files, exported from the same start point as before.

$31 per song, paid by card.

We place the new files, rebalance the mix around them and send back an updated release-ready WAV.
For a song that is already mixed and mastered: you send a new vocal take, a different sample or an added part, and we put it into the existing session and adjust the mix around it.
Make an Order*Price depends on the project size — calculate your exact price on the order page. Not happy with the result? See our refund policy.
Stem replacement is $31 per song. You get an updated, release-ready WAV back, usually in 2–3 days per song, and you can still ask for changes in the revision rounds.
If the arrangement or tempo changes, or the song needs a different mix direction, it is a new mix: order Mixing. To clean up or swap sounds before the song is mixed, use Music Editing. If only the master needs to change, order Mastering or Stem Mastering.
Sometimes the mix and master are done, and only then you hear what you want to change: a vocal line you want to re-sing, a sample or synth preset you want to swap, a part you want to add. Revision rounds cover changes to the mix, not new audio. Stem replacement is for new audio.
Stem replacement is only for songs we mixed and mastered, because we work in our original mix session. Make the change in your own session and resend the multitrack. Our engineers place the new files in the mix session, adjust levels and effects so they sit like the original, and send back an updated master. You don’t pay for a new mix or a new master.
A named engineer listens properly and writes back with exactly what is holding the track back and what to do about it. Free, always — no card, no order first, and no obligation to use us afterwards.
