Sound for advertising: from brief to finished spot

Sound for advertising is the assembly of several layers — voice-over, music, effects and the mix — into a dozen or so seconds that have to sell an emotion and stick in the memory. In a spot every second is worth its weight in gold, which is why sound is not an add-on but half the message. See what the journey from brief to finished file looks like.

Why sound decides an advertisement’s effectiveness

A viewer often watches an advertisement “out of the corner of their eye”, but hears it in full — in the background, on headphones, in the car. Well-designed sound can hold attention even when no one is looking at the screen. A distinctive musical theme, an expressive voice-over and polished effects build brand recognition as strongly as a logo.

Stage 1: Brief and analysis of the material

Everything starts with a conversation. We establish:

• the goal and tone — whether the spot should be energetic, warm, prestigious, funny,
• the target group and channels — an advertisement for television sounds different from one for social media,
• fixed elements — whether the brand has its own jingle, voice-over, musical theme,
• deadlines and versions — how many lengths and language variants will be needed.

At this stage we watch the picture edit and establish what we build from scratch and what is already finished.

Stage 2: Voice-over and voice

The voice is usually the backbone of the spot. As part of voice recording we help select a voice-over artist or actor, and record the lines in a soundproofed booth on a Neumann TLM 102 microphone. We always capture several interpretations — faster, slower, warmer — so there is something to choose from. If the spot has language versions, we record them coherently, keeping the same character in every language.

Stage 3: Music

Music gives an advertisement pace and emotion. We have two routes:

• original composition — music production to a specific picture, perfectly matched to the cuts and accents; it is created by Yohan, who handles music and the mix with us,
• licensed library — a faster and cheaper choice when budget or time are limited; we select a track and adapt it to the length of the spot.

Which route to choose, we decide together with you at the brief stage.

Stage 4: Sound design and effects

This is where the spot comes to life. As part of sound design we add sound effects — from subtle “whooshes” at transitions, through product sounds (a crunch, a gurgle, a click), to building the scene’s space. We draw on a 4 TB library and, when needed, record dedicated sounds. It is precisely the effects that make the product on screen feel tangible.

Stage 5: Mix and mastering for the platforms

At the end all the layers come together in Pro Tools Ultimate on an Avid S1 console. The mix levels the volumes, sets the voice above the music so it stays intelligible, and organizes the space. Key here is mastering for loudness standards: television, YouTube, Meta and Spotify have different requirements (e.g. the EBU R128 standard for broadcast). We deliver the spot in several versions — full and cut-downs — and in outputs tailored to each platform.

Sound branding — sound that builds the brand

It is worth thinking of an advertisement’s sound not as a single spot, but as an element of sound branding — a coherent sonic identity for the brand. A recurring musical theme, a distinctive jingle or a consistent voice-over make the audience recognize the brand before they see the logo.

If you are planning a series of spots or a longer campaign, it is good to design such fixed elements right away: a short theme (an audio logo), a palette of sounds and guidelines for the voice-over. This way subsequent advertisements are consistent, and producing each new one is faster and cheaper, because it builds on a ready-made foundation.

How long and how much does sound for an advertisement cost?

A simple 30-second spot we can wrap up in one or two working days. Original music, voice-over casting and several language versions extend the process to a few days. The cost depends on the scope — we quote a mix of finished elements differently from a full production with music and a voice-over. We give this as a guide only; we’ll prepare an exact quote after reviewing the brief.

Summary

Sound for advertising is a process: brief, voice-over, music, sound design and a mix for the platforms. Each of these elements can be done with us separately or assembled into one coherent production. The result is a spot that sounds professional and works for the brand in every channel.
