How a Modern Music House Delivers Work in 2026
Delivery is the part of motion picture advertising music that almost no one writes about. Composers post about gear. Music supervisors post about taste. Agencies post about ideas. Nobody posts about the half-day at the end of every project where the cue has to leave the studio, land cleanly in someone else's system, and survive the next eight months of revisions. That half-day is where music houses earn or lose a working relationship.
At Tonal Chaos we deliver music and sound design every week to agency creatives, network promo teams, trailer editors, and brand-direct producers. Here's what that process actually looks like in 2026, and why we built the delivery layer we did.
The file standards
Every cue leaves our studio as a 24-bit, 48 kHz WAV master. We also render a 16-bit, 44.1 kHz alt for legacy ingestion pipelines, a stereo broadcast version peak-normalized to minus two dBTP and loudness-normalized to minus twenty-three LUFS for European broadcast or minus twenty-four LKFS for US broadcast, and a streaming-spec version normalized to minus fourteen LUFS for digital placements.
Stems get split into music bed, sound design only, full mix, percussion only, melodic only, risers and transitions only, and any custom layers the brief requested. Most agencies will only ever use the full mix and the music bed, but the supervisors who come back to us a second time are almost always the ones who needed the granular stem split a week into the cut.
Every file gets metadata baked into the WAV itself. Title, composer, publisher, ISRC code where applicable, BPM, key, duration, contact email. We also embed broadcast wave metadata so any cue we deliver shows up correctly in the agency's media asset management system without anyone having to re-tag it.
The cue sheet and the paperwork
A cue sheet ships with every delivery. Composer split, publisher split, performance rights organization affiliation, master and sync clearance language, and any restrictions on the use of the cue. Music houses that skip this step are the music houses that get one project per agency.
We also include a one-page tear sheet for the project. What the cue is called, what the brief was, what we delivered, what supervisor signed off, what changes happened in revision. That document sits with the cue in our system permanently, so if the same supervisor calls us about a similar brief three years from now we can pull the entire history of the relationship in under a minute.
How it gets sent
For years the industry standard for delivery was a Dropbox link, a WeTransfer link, or a zip file in an email. All three work. None of them are how a premium music house should be delivering in 2026.
We send every project through DropCue. Each delivery is a branded share page with the agency's project on it, the cues sequenced, the stems available as one-click downloads, and timestamped comment tools the supervisor can use to mark exactly where they want a change. Per-recipient analytics tell us who opened the link, what they listened to, and what they downloaded. The whole package sits at a single URL that the supervisor can come back to a year later when the project enters another revision cycle.
(For full transparency, we built DropCue ourselves after years of watching the WeTransfer-and-email workflow lose stems and corrupt zip files. So when we mention it in posts like this, that's us talking about a tool we made because we needed it. We use it in our own studio every day.)
Security
Music delivered to a major studio campaign or a network branding rebrand carries real watermark and confidentiality obligations. We deliver watermarked work-in-progress files when the contract requires it, full unwatermarked masters only after final approval, and we use share-link expiration on every pre-release delivery so nothing leaks beyond the original recipient.
Why the delivery layer matters
Music houses get re-hired for two reasons. The work is great, and the work is easy to use. The agencies and supervisors we have ten-year relationships with stay with Tonal Chaos because they know what's going to land in their inbox, in what format, with what paperwork, and at what time. Predictability at the delivery layer is how a premium music house builds a roster of repeat clients.
