Adding Sound Effects to Your Video

Sound effects bring your video to life at the moment level. A sharp impact hit on a cut, a subtle ambient background, a notification chime — these small additions make video feel produced and intentional. PublishFi's built-in SFX library gives you access to thousands of clips across multiple categories, all searchable by keyword, category, license, tags, and duration.

Opening the SFX tab

Open the audio panel by clicking the music icon in the right-side panel of the editor. At the top of the panel, click the SFX tab. The tab opens to a search view where you can start finding clips immediately.

Searching for a sound effect

Type a description in the search bar — "rain," "swoosh," "crowd," "alarm," or any keyword that describes the sound you need. Results load automatically as you type and display the clip name, creator username, category, tags, and duration.

Each clip shows a waveform visualization below the name. Click the play button to preview the audio directly in the panel.

Tip: Popular search terms like "impact," "whoosh," "click," "ambient," "footsteps," "fire," and "thunder" tend to surface a wide range of usable results. Start broad, then narrow with filters.

Filtering SFX results

Below the search bar, click Filters to reveal additional controls:

• Category — choose from categories such as Sound effects, Soundscapes, Music, Speech, or Instrument samples to focus your search on a specific type of audio.
• License — filter by the clip's usage license. The available options are CC0 (public domain, no restrictions), CC-BY (requires attribution), CC-BY-NC (attribution, non-commercial use), or Sampling+ (allows sampling in new works). A small license icon on each clip row also indicates its type at a glance, with a tooltip showing the full license name.
• Tags — add one or more descriptive tags from the available list — nature, ambient, impact, whoosh, click, beep, water, wind, fire, explosion, footsteps, rain, thunder, bird, alarm — to narrow results to clips that match multiple descriptors.
• Duration — drag the range slider to set a minimum and maximum clip length. The range spans up to 8 minutes, though most SFX clips are a few seconds long.

To remove all active filters at once, click Reset filters.

Placing a sound effect on the timeline

When you find the right clip:

1. Move the playhead in the timeline to the exact frame where you want the effect to begin.
2. Click the + (Add to timeline) button on the right side of the clip row.

The SFX clip is placed at the playhead position and appears in amber on the timeline. This color coding makes SFX clips visually distinct from music clips (green), voiceover clips (violet), and custom audio (blue), so you can see your audio layers clearly even in a dense edit.

Working with SFX clips on the timeline

Once placed, SFX clips behave like any other audio clip:

• Reposition — drag the clip left or right along the timeline.
• Trim — drag either edge to shorten the clip from its start or end.
• Delete — right-click the clip and select Delete.

Tip: SFX clips can overlap with music and voiceover clips. Stacking a specific sound effect on top of your background music at a key moment — a logo reveal, a transition, a punchline — is a common technique that adds impact without complicating the edit.
