Audio post-production
Post-audio for film, from first cue to final stem.
Harmonic Alchemy is a post-audio studio founded by Jeffrey Carabelos in 2020 that contracts with audio professionals worldwide. It covers each stage of the post-audio workflow, from score and mix through sound design and delivery, so a production meets professional standards without juggling vendors.
Film music mixing and score mixing
A score can be beautifully written and still lose the room in the mix. Music mixing for film balances the cue against dialogue and effects before it reaches the dub stage, so the re-recording mixer receives material that already sits where it should.
Music editing and score delivery
Music editing keeps cues locked to a picture that keeps changing, from conforms and alternates to cutdowns and festival versions. Delivery includes organised stems, the full mix, alternates, and documentation that matches your post house's spec.
Immersive and surround music mixing
Immersive audio mixing places music in the room rather than in front of it. Surround and object-based music mixes are prepared alongside the stereo mix so both versions come from the same intent instead of an afterthought upmix.
Sound design
Harmonic Alchemy provides full-service sound design, in addition to sound-designed based scoring. Where score and sound design overlap, like a rising texture that becomes a scream or a room tone that becomes a chord, having both handled in one studio means they are written together instead of colliding on the stage.

Questions from filmmakers
What do you deliver to the final mix team?
Score delivery can include the full mix, organised stems, alternates, and documentation for your post team. Share your post house's requirements early so the delivery plan matches what they need.
Can you prepare surround or immersive music mixes?
Harmonic Alchemy handles surround and immersive music mixing alongside stereo. We are equipped to deliver in stereo, 5.1, 7.1, 9.1 and Dolby Atmos. Tell us which formats your production needs and share the final mix team's specifications so we can agree on the deliverables before work begins.
