How to Add Background Music in Descript

Most people record a clean voiceover, tighten their cuts, and think they’re done.

Then they hit play — and it sounds flat. Empty. Like a room without furniture.

That’s the gap background music fills. It’s not decoration. It’s the emotional layer that keeps viewers locked in, signals professionalism, and makes your content feel like something worth finishing.

Here’s what the data shows: videos with background music retain viewers up to 80% longer than silent or voiceover-only content. And according to a Nielsen study, 96% of branded video content with music is more memorable than content without it. That’s not a small edge — that’s the difference between someone watching to the end and clicking away at second three.

The good news? If you’re already using Descript, you’re a few clicks away from a professional-sounding track under every video you make.

This is the complete guide on how to add background music in Descript — from importing your file to mastering the final export.

Why Background Music Is Non-Negotiable for Your Videos

Before we get into the how, let’s get clear on the why — because skipping background music isn’t a neutral choice. It actively costs you.

Retention drops without audio texture. Human brains are wired to disengage when environments feel too quiet. Silence triggers discomfort. Music triggers comfort. Studies show music increases average watch time by 35–40% across educational and tutorial video formats.

Music signals production quality. In a world where 500 hours of video are uploaded to YouTube every minute, production value is a trust signal. If your video sounds professional, viewers assume your content is professional — before you’ve said a word.

It controls emotional pacing. The right track tells the viewer how to feel at every moment. Upbeat background music creates energy during lists and tips. Slower, ambient music creates focus during explanations. You’re not just editing video — you’re directing emotion.

91% of video marketers say video content has given them strong ROI (Wyzowl, 2024). Background music is one of the lowest-effort upgrades to help you get there.

What You Need Before You Start

You need two things before you open Descript:

A Descript account with your video or audio project loaded. Background music is added at the project level, so you’ll need at least a rough cut ready.

A royalty-free music file. This is critical. Using commercial music without a license will get your video removed or muted on YouTube, Instagram, and LinkedIn. Use sources like:

• Epidemic Sound — subscription-based, huge library, full licensing
• Artlist — creator-favorite, annual license covers all platforms
• YouTube Audio Library — free, no attribution required
• Pixabay Music — free, royalty-free, no account needed
• Uppbeat — free tier available with attribution

Download your track as an MP3 or WAV file before you move into Descript.

How to Add Background Music in Descript (Step by Step)

Open Your Project and Go to the Timeline View

Log in to Descript and open the project you’re working on. Make sure you’re in Timeline view — this is where you see your audio and video tracks layered horizontally. If you’re in Script view, toggle to Timeline in the top bar.

You need the Timeline view to properly layer your music beneath your voiceover or spoken content.

Import Your Music File

Click the + icon in the left panel or go to File > Import. Select your downloaded music file from your computer.

Descript accepts MP3, WAV, M4A, and most common audio formats. Your file will appear in your media library on the left side of the screen once imported.

Pro tip: Give your music file a clear name before importing — something like “BG-music-upbeat” makes it easy to find in longer projects.

Drag the Music Onto a New Track

Find your music file in the media panel and drag it down to the timeline. Drop it below your existing audio or video track — this creates a new layer specifically for background music.

Descript automatically creates a new audio track when you drop a file below existing tracks. Rename this track “BG Music” by double-clicking the track name so your timeline stays organized, especially on longer projects.

Trim and Position the Music

Click on the music clip in the timeline. Use the handles at the start and end to trim the clip to match your video’s length.

If your music is shorter than your video, you can:

• Loop it — right-click the clip and select “Loop” to repeat it seamlessly
• Layer multiple clips — drag the same file again and line it up end-to-end
• Crossfade — overlap clips slightly and use the fade handles for a smooth transition

Position the start of your music clip to match exactly where you want it to begin. Most creators start music 0–2 seconds after the video opens so the edit doesn’t feel abrupt.

Adjust the Volume Level

This is where most beginners get it wrong. They add music and leave it at 100% volume — which drowns out everything else.

Click on the music clip in the timeline. On the right side panel, you’ll see a Volume slider. Pull this down to between 15% and 30% as a starting point.

The rule: your voice should always be the loudest element in the mix by a clear margin. Background music should be felt, not heard. If someone can clearly make out the lyrics or melody without effort, it’s too loud.

A good benchmark: voiceover at 100%, background music at 15–25%.

Use Ducking for a Professional Mix

Ducking is the technique that makes background music automatically drop in volume when someone speaks and rise again during pauses. It’s what separates amateur audio from professional-sounding production.

To enable ducking in Descript:

1. Click on your background music track in the timeline
2. Open the Inspector panel on the right
3. Look for the “Duck when other tracks play” toggle and enable it
4. Set the ducking amount — a –12dB to –18dB reduction works well for most voices
5. Adjust the attack and release times to control how quickly the music fades and returns

Once ducking is on, your mix will feel natural and balanced without any manual volume automation. This single setting is the #1 upgrade most Descript users are not using.

Add Fade In and Fade Out

No one wants music to abruptly start and stop. Add fades at both ends.

Hover over the very start of your music clip in the timeline — you’ll see a small fade handle appear. Click and drag it right to create a fade-in. Do the same at the end of the clip, dragging left for a fade-out.

A 1–2 second fade in at the start and a 2–4 second fade out at the end is the standard.

For longer videos, you can also add micro-fades between sections to create natural pauses in the music when you transition topics.

Preview and Adjust

Hit play on your project and listen through. Focus on three things:

1. Can you clearly hear every word of your voiceover? If not, lower the music.
2. Does the music feel right for the tone of your content? If it’s fighting your message, swap the track.
3. Do the fades feel smooth? Abrupt music transitions are one of the most distracting editing mistakes.

Run through this at least twice — once with headphones, once without. Headphones will catch subtle imbalances that regular speakers miss.

Export Your Video with Music

Once your mix sounds right, go to File > Publish or click the Export button.

Select your export format — MP4 for video, MP3 for podcast/audio. Make sure the “Include audio” toggle is on and that your background music track is not muted.

Click Export and let Descript render your final file with the music baked in.

Best Background Music for Different Video Types

Not all music works for all content. Here’s a quick reference:

Tutorial and how-to videos — Light, upbeat, instrumental. Lo-fi beats or soft electronic works well. The goal is energy without distraction.

Testimonials and case studies — Warm, minimal, ambient. You want the story to carry. Music should be invisible.

Promotional and product videos — Upbeat, high-energy, branded. This is where you can push tempo and build excitement.

Educational deep-dives — Minimal ambient or completely silent. If the content is complex, music can compete with comprehension.

LinkedIn and professional content — Corporate acoustic, soft jazz, or neutral instrumental. Avoid anything that sounds too casual or aggressive.

Tip: Match the BPM (beats per minute) of your music to the pace of your editing. Fast-cut montage content needs a higher BPM. Slow explainer content needs something under 90 BPM.

Common Mistakes That Kill Your Audio Mix

Using music with lyrics under a voiceover. Lyrics compete directly with speech. The brain cannot process two streams of language simultaneously. Always use instrumental tracks under voiceover.

Leaving the volume too high. This is the most common mistake. If your music is noticeable, it’s probably too loud. Aim for music that people would miss if it disappeared — not music that dominates.

Starting music exactly at frame one. Abrupt music openers feel jarring. Start with a 1-second fade-in or a half-second of silence before the music comes in.

Using the same track for the entire video. On longer videos (10+ minutes), the same looping track gets fatiguing. Layer two or three different tracks across sections to keep the audio environment fresh.

Skipping the ducking setup. If you’re not using ducking, your final mix will feel amateurish — even if every other production element is polished. Turn it on, always.

Exporting with a muted track. Check your tracks before you export. One accidentally muted layer means silence in your final video. Preview before you render.

Tips for Using Background Music Across a Full Content Strategy

Background music is one piece of a broader production system. The creators who get consistent results treat every element — hook, script, editing, audio — as a system they optimize over time.

Create a music library. Build a folder of 10–15 pre-approved tracks across different moods. This saves hours of searching and keeps your brand sound consistent across every video you publish.

Sync music to your editing rhythm. Cuts that land on beats feel intentional. Most pro editors make their cuts hit on the downbeat or the one. Listen to your track before you start cutting and use the beat as a guide.

Test with your audience. Run the same content format with and without background music using A/B style uploads. Track average view duration. The data will tell you more than any opinion.

Volume-normalize your final export. Descript has a normalization option in export settings. Use it. It ensures consistent playback across devices and prevents your audio from sounding too quiet or too loud depending on where viewers are watching.

72% of marketers say video has improved their conversion rate (Wyzowl). The investment you make in audio quality directly compounds those results.

Conclusion

Adding background music in Descript is a straightforward process — but getting it right requires attention to detail most people skip.

The steps are clear: import your file, drop it on a new track, trim it to fit, set volume between 15–25%, enable ducking, add fades, and export with your audio tracks live.

The results are not small. Better audio means higher retention, more trust, more shares, and content that sounds like it was built by someone who takes their work seriously.

Start with one video. Set up your music layer using this guide. Listen back. Then build the habit until every piece of content you make sounds like it belongs at the top.
