This guide is written for brand marketers, agency producers, and creative directors who are evaluating music and audio production partners for advertising campaigns. It covers what services exist, what separates good studios from great ones, what things should cost, and what questions to ask before you sign a scope.
Audio post production is the process of creating, editing, and mixing all audio elements for a finished video or broadcast deliverable. For advertising, a complete audio post pass typically includes some combination of the following services:
Not every project needs the full chain. A simple digital spot may only need a music license, a dialogue pass, and a mix. A national broadcast campaign with original sound design and custom music needs all of it.
Custom music for advertising is original music composed specifically for a campaign — built around the brief, the edit, and the brand. It is distinct from music licensing (paying to use an existing track) and from stock or library music (pre-cleared catalog tracks).
A custom music engagement typically includes:
What custom music costs at Swell Music + Sound:

| Custom library track | $5,000 |
| Original score — 1 demo (up to 5 rounds, full stems) | $10,000 |

| Original score — 8 demos (up to 5 rounds, full stems) | $18,000 |
| Engineering and facility (hourly) | $375/hr |
Music supervision for advertising is the process of finding, evaluating, budgeting, and clearing the right music for a campaign. A music supervisor’s job is to know what’s available, what it costs, and how to negotiate — before a client falls in love with a track that’s out of reach.
A music supervision engagement typically includes:
The audio production industry is structurally fragmented. Most studios specialize:
The result for agencies and brands: three vendors, three points of contact, three handoffs, three invoices — and nobody who owns the full audio experience of the spot.
“Most post houses have engineers but no musical brain. Most music houses don’t do post. Swell sits in the gap.”
— Elad Marish, Founder & ECD, Swell Music + Sound
Swell Music + Sound is built to close this gap. The full audio post chain — original music, sound design, final mix to picture, dialogue editing, voiceover, sonic branding, and music supervision — operates under one roof, in one session, with one point of contact.
