Most video editors and motion graphics designers treat sound as an afterthought. They finish the visuals, slap a royalty-free track underneath, and call it done. This is a massive mistake — and one that instantly reveals the difference between amateur and professional work.
Sound is not decoration. Sound is half the experience. Watch any scene from a great film with the audio off and you'll feel the difference immediately. The same is true for motion graphics, brand videos, social media content and anything else you create.
Here's how to get started with sound design — even if you have no music background and have never touched audio software before.
Understanding the Layers of Sound
Professional sound design for video typically involves several distinct layers working together. Understanding these layers is the first step to thinking like a sound designer.
The Tools You Need
Where to Find Sound Effects and Music
You don't need to create every sound from scratch — especially when you're starting out. Here are the best sources:
- Freesound.org — Massive free library of sound effects uploaded by a global community. Quality varies but there are gems everywhere.
- Epidemic Sound — Subscription-based. Excellent quality music and SFX, all properly licensed for commercial use.
- Artlist — Similar to Epidemic Sound. Annual subscription with unlimited downloads and full commercial licensing.
- Mixkit — Free sound effects and music tracks. Quality is surprisingly good for a free resource.
- YouTube Audio Library — Free music and sound effects from Google. Good for projects where budget is tight.
- Zapsplat — Free account gives access to thousands of professional sound effects.
Mixing Levels — The Numbers That Matter
Most beginners have no idea what their audio should actually measure. They go by feel — which leads to videos that are too quiet on speakers, or painfully loud on mobile. Professional mixing uses loudness targets. Here's what to aim for:
- Dialogue/voiceover: Peaks should sit around –6 dB, average (LUFS) around –18 to –20 LUFS. This gives you headroom and keeps speech clear.
- Music bed under dialogue: Should sit roughly –20 to –25 dB below dialogue. If you can't understand every word clearly with music playing, the music is too loud.
- Sound effects: Vary by type. Subtle UI sounds: –20 to –30 dB. Impactful hits: can peak at –6 to –3 dB for emphasis.
- Final mix output for YouTube/social media: Aim for –14 LUFS integrated — YouTube's standard. Premiere Pro and DaVinci Resolve both have loudness meters to check this before export.
- For broadcast/TV: –23 LUFS (EBU R128) or –24 LUFS (ATSC A/85 for the US). Check client requirements.
Quick check: Export your video, play it next to a professional YouTube video from a brand you admire. If yours sounds quieter, tinnier, or more compressed, your mix needs work. Use your ears to compare — loudness meters tell you numbers, but your ears tell you truth.
Basic EQ — Shaping Your Audio
EQ (equaliser) lets you boost or cut specific frequency ranges in your audio. You don't need to be a mastering engineer — you need to know a few key moves that fix the most common problems.
A Practical Audio Layering Workflow
Here's the exact sequence I follow when adding sound to any video project. This works whether you're in Premiere Pro, Resolve, or After Effects.
- Lock picture first. Never start mixing until the video edit is locked. Adjusting audio timing after picture changes is painful and wastes time.
- Import and organise your audio files into labelled bins: Music, SFX, VO/Dialogue, Ambience.
- Place voiceover/dialogue first on its own track. This is the king layer — everything else works around it.
- Add music bed. Choose a track that fits the energy, then lower it to where it feels supportive but invisible under dialogue.
- Add ambient sound. Even a quiet room tone adds realism. For motion graphics, subtle electronic hum or atmospheric texture works well.
- Add SFX for key visual moments. Go frame by frame and add a sound for each significant animation: text appearing, transitions, reveals, impacts.
- Apply EQ and dynamics to each track individually, then to the master bus.
- Check your loudness levels with a LUFS meter and adjust the master output.
- Export and review on multiple devices — laptop speakers, phone, earphones, monitor speakers. Your mix should hold up across all of them.
Sound Design in Nepal's Video Market
Most video production work I see in Nepal — brand videos, NGO documentary content, restaurant promos, tourism reels — suffers from the same audio problems: thin dialogue, music that's too loud, and zero sound design beyond background music. This is a gap that represents a real opportunity for any designer willing to invest in audio skills.
Nepal's tourism sector in particular produces enormous amounts of video content — trekking companies, travel agencies, heritage tourism operators. These clients need videos that make international audiences feel the atmosphere of the Himalayan landscape. Great audio — the sounds of wind on Annapurna, prayer bells in Bhaktapur's Durbar Square, the rhythm of Newari music under a cultural montage — elevates that content dramatically and commands higher rates.
For local brand videos (restaurants, retail, events), clean voiceover mixing and subtle SFX add a polish that most local production houses don't bother with. If you can reliably deliver that, you become the go-to for clients who want to look premium.
The Most Important Principle — Less is More
The beginner's instinct is to add more sound — more effects, louder music, more layers. The professional instinct is to subtract. Every sound in your mix should earn its place. If removing a sound makes the piece feel the same or better, remove it.
The goal of sound design is not to fill silence. It's to make the audience feel what you want them to feel without them noticing the audio at all. When sound design is working perfectly, viewers don't think about the audio — they just feel the emotion.
A Simple Practice Exercise
Take any short motion graphics piece you've already made — even just 15-30 seconds. Mute all the audio and watch it. Now add just three things: background music, two or three sound effects for key animation moments, and a short reverb tail at the end. Export it and compare it to the original.
You will immediately hear — and feel — the difference. That exercise alone teaches you more about sound design than any amount of reading theory.
Getting Better Over Time
Like all creative skills, sound design improves with practice and attention. Start actively listening to the audio design in commercials, films and videos you watch — not just the music but the sound effects, the room tones, the way audio transitions between scenes. This kind of critical listening is how your ear develops.
Start with Earworm and Practitioner's Ear — YouTube channels dedicated to audio analysis of film sound. Watch how professionals break down the audio design in major productions. Every video you watch professionally becomes an opportunity to study sound craft.
Sound is a skill worth investing in seriously. In a world where most designers ignore it entirely, even basic competence in audio will make your work stand out significantly. Clients notice — even when they can't articulate why one video "feels better" than another. The answer is almost always the audio.
