Sound effect file formats explained

Work in WAV and deliver in whatever the destination asks for. WAV is uncompressed, so it survives every edit, level change and re-export without degrading; MP3 and AAC are compressed for delivery and lose a little each time they are re-encoded. FLAC sits between them: compressed, but losslessly.

For a two-second sound effect the storage argument barely applies, which is why the working-format decision is easier here than it is for music.

Sound effect formats compared

The formats you will actually meet

Most sound effect work comes down to three families of format, each with a clear trade between quality and size.

• WAV is uncompressed audio. It keeps the full detail of the recording, so it is the best choice while you are editing, layering, or mixing. The cost is size, since a WAV file is far larger than a compressed one.
• MP3 is compressed and lossy, meaning it drops some data to shrink the file. For most listeners the loss is hard to notice, which is why MP3 is the everyday format for sharing and web playback.
• AAC is also lossy but generally sounds better than MP3 at the same size. It is the standard inside a lot of video containers and mobile apps.
• OGG (Vorbis) is an open, lossy format popular in games and open source projects, prized for small files and no licensing friction.

Lossless versus lossy, and why it matters

Lossless formats like WAV preserve every sample of the original audio. Lossy formats like MP3, AAC, and OGG throw away information the format judges to be less audible, which makes the file smaller but permanently removes detail. The practical rule is to work in a lossless format and compress only at the end. If you edit an MP3, export it, then edit that export again, each pass compresses already-compressed audio and the quality slips a little further each time.

When to use each format

• Editing and layering: use WAV so you keep full quality while you cut, stack, and adjust levels.
• Final video or podcast: AAC or a well-encoded MP3 keeps the file small without an audible drop for most audiences.
• Games and interactive apps: OGG or a short WAV, depending on whether your game values small size or instant, decode-free playback.
• Archiving your own library: keep the WAV master so you can re-export any compressed version later without a second round of loss.

Export tips that keep quality high

• Match the sample rate to your project, commonly 44.1 kHz for audio-only work and 48 kHz for video, so the clip does not get resampled on import.
• Choose a sensible bitrate for lossy exports. Around 192 kbps or higher for MP3 keeps sound effects crisp.
• Keep a lossless master of anything you might reuse, then generate compressed copies from it as needed.
• Name files clearly so you can tell the master from the compressed version at a glance.

Where Morphic fits

Morphic generates original sound effects from a text description. You describe the subject, texture, space, and length you want, pick from what it renders using models such as ElevenLabs and Seed Audio, and download the clip to drop into your editor. That means you can create the exact cue you are missing rather than digging through a stock pack, then export it in the format your project needs. On paid plans the effects are yours to use commercially, so check the terms for your plan. If you would rather browse ready-made cues first, the Morphic sound library is a good place to start, and the same workspace also covers music and voiceover.

Every term here can be filled with a generated cue. The impacts, whooshes and ambience pages each open in Studio with a working prompt already in the box.
