Short answer: edit with WAV and keep MP3 for previews or when file size matters. WAV is uncompressed and lossless, so it survives layering and processing without degrading. MP3 is smaller but lossy. Here is the full breakdown for video editors.
The answer
Both play in every editor. The difference is what happens to quality as you edit, layer, and process the sound.
Step 01
WAV is uncompressed and lossless, meaning it stores the full audio with no quality thrown away. Sound effects are short and full of sharp transients, exactly the detail lossy compression damages first. When you layer multiple SFX, adjust levels, add EQ, or time-stretch, WAV preserves headroom and clarity through every step. For any work that will be published, start from WAV when you have it.
Edit in WAV to keep full qualityStep 02
MP3 is compressed, so files are roughly a tenth the size of WAV. That makes it ideal for fast previews, browsing a large library, or downloading on a slow connection. The trade-off is a small, permanent quality loss that cannot be recovered. For a single quick SFX dropped into a casual edit, MP3 is usually indistinguishable. For layered professional mixes, the loss compounds.
MP3 trades a little quality for sizeStep 03
The standard for video audio is 48kHz sample rate and 24-bit depth. This matches what cameras and editors expect, avoids resampling, and gives you headroom for mixing. When you download WAV sound effects, 48kHz/24-bit is the spec to look for. MP3 has no bit depth, but 320kbps is the quality to aim for if you use it.

Edit from WAV whenever it is available, especially for sounds you will layer or process heavily. Use MP3 to preview and audition quickly. Remember that your final video export re-encodes all audio into the delivery format anyway, but starting from lossless WAV means that final encode begins from the cleanest possible source.

Tip 01
When you render your video, the audio is compressed into the platform delivery format regardless of your source files. That does not make WAV pointless: starting from lossless means every edit and the final encode begin from a clean source, so artifacts never get baked in early and multiplied.
Tip 02
A 320kbps MP3 is hard to distinguish from WAV for most single sound effects. The audible damage comes from low-bitrate files (128kbps and below), where transients smear and high frequencies dull. If you use MP3, use high-bitrate versions.
Tip 03
Every individual sound on the site previews and downloads as MP3, so you can grab one fast with no signup. The full bundle ships studio-grade 48kHz/24-bit WAV alongside MP3, so you have the lossless version for serious editing whenever you need it.
FAQ
For editing, yes. WAV is uncompressed and lossless, so it preserves full quality through layering, level changes, and processing. MP3 is lossy and degrades slightly, which matters most in layered professional mixes.
Yes, especially for casual edits or quick previews. A high-bitrate MP3 (320kbps) is hard to distinguish from WAV on a single sound. For professional or heavily layered work, WAV is preferred.
48kHz sample rate and 24-bit depth is the standard for video. It matches camera and editor expectations, avoids resampling, and leaves headroom for mixing.
Yes. MP3 uses lossy compression that permanently discards some audio data, affecting sharp transients and high frequencies first. The loss is small per file but compounds when sounds are layered and processed.
Individual sounds preview and download as MP3 with no signup. The full bundle includes studio-grade 48kHz/24-bit WAV files alongside MP3.
Rarely on a single sound effect, especially at high bitrate. The difference becomes audible in dense, layered mixes where compression artifacts from many MP3s add up.
