Most clients reviewing a corporate video cut focus entirely on the picture — the framing, the colour grade, the edit rhythm. The audio gets a fraction of the attention. This is a mistake. Sound design accounts for roughly half of a viewer's emotional experience of any video. Get it wrong and even the best-looking corporate film feels flat, cheap, or unconvincing.
Audio Visual Lab's post-production team handles complete sound design and audio finishing for corporate video, brand films, TVCs, training content, and social media production. Here is what sound design for corporate video actually involves — and why it matters more than most clients realise.
What Sound Design Is (and What It Is Not)
Sound design is not simply "adding music." It is the deliberate construction of an audio environment that supports and amplifies the story being told. For corporate video, it encompasses:
- Dialogue editing — Cleaning location audio, removing noise, correcting sync, and balancing levels across different recording environments
- Music scoring and licensing — Selecting or commissioning music that fits the brand's tone without clichéd or generic choices
- Ambient sound design — Building the background environment of each scene so it feels inhabited and real
- Sound effects — Subtle audio cues that reinforce visual moments without drawing attention to themselves
- Voice-over production — Direction, recording, and mixing of narration or presenter audio
- Audio mastering — Final level normalisation, dynamic range optimisation, and format-specific delivery for broadcast, web, social, and cinema
Why Audio Quality Directly Affects Brand Perception
Research in media psychology consistently shows that poor audio — wind noise, inconsistent levels, echoey location sound — causes viewers to rate the entire video as lower quality, regardless of how good the picture looks.
For a South African brand investing R50,000 or more in a corporate video, inadequate audio post-production on a fraction of that budget undermines the entire investment. Conversely, strong sound design elevates modest production footage. A well-scored, cleanly mixed corporate film will consistently out-perform a beautifully shot film with poor audio.
AVL's Audio Post-Production Workflow
Here is how AVL's audio post-production process works on a standard corporate brief:
1. Audio Review and Dialogue Edit
Every location audio clip is reviewed, cleaned, and synced. Problem recordings are treated with noise reduction and EQ correction. No location audio is used unchecked.
2. Music Brief and Selection
We discuss the brand's tone — formal or warm, energetic or authoritative, contemporary or classic — and present 3–5 music options before committing to a direction. Music is licensed from professional libraries for commercial use, eliminating any copyright exposure for the client.
3. Ambient and Effects Build
We build ambient layers under dialogue sequences so each environment feels real. Sound effects reinforce key visual moments without drawing attention to themselves.
4. Voice-Over (Where Applicable)
Script finalisation, talent direction, studio recording, and integration into the cut — or remote voice-over session management if the preferred talent is in another city.
5. Final Mix and Master
Full stereo mix with correct loudness standards for the intended platform — LUFS targets vary between broadcast, YouTube, Instagram, and cinema. Stems (music, dialogue, effects separately) are delivered for future versioning.
Sound Design for Social and Short-Form Content
Short-form video for social media has its own audio requirements. Content often plays without sound until the viewer actively unmutes — meaning the audio mix must work both with and without headphones, and music must be louder relative to voice compared to broadcast norms. AVL mixes social content to platform-specific loudness standards for Instagram, TikTok, YouTube Shorts, and LinkedIn.
Our post-production services cover every audio deliverable from a single social cut to a full broadcast master.
Frequently Asked Questions
Does AVL handle sound design in-house?
Yes. All audio post-production is handled in-house by AVL's post-production team. We do not outsource audio work.
What if the location audio from our shoot is poor quality?
Location audio can almost always be improved through noise reduction, EQ, and dialogue restoration processing. If the damage is beyond repair, we will advise on re-recording options including ADR or voice-over.
Do you compose original music or use licensed tracks?
Both. For most corporate briefs, high-quality licensed music is the right choice — cost-effective and wide-ranging. For flagship brand films or TVCs requiring a distinctive sonic identity, we can commission original composition.
What formats do you deliver audio in?
The final mix embedded in your required video format (H.264, ProRes, etc.) plus isolated stems — music, dialogue, and effects separately — for future versioning and language adaptation.
How much does audio post-production add to a production budget?
For standard corporate videos, audio post-production is included within AVL's production fees. Larger-scale productions requiring original music composition or intensive dialogue restoration are quoted separately.
