Audio Format Comparison
| Format | File Size | Best For |
|---|---|---|
| WAV | big | Recorded materials, editing, and intermediate storage with quality maintained |
| MP3 | small | Playback on a wide range of devices, general distribution |
| OGG（Vorbis） | small | If you want to distribute on the web or in compatible apps, or use an open format. |
Conversion steps
- Load the audio file and check the original format and playback time.
- Select the format that is compatible with the output destination app or device.
- Convert without increasing the bit rate, sample rate, or number of channels more than necessary.
- Play the beginning, middle, and end, and check for any cutouts or missing left and right channels.
How to maintain sound quality
MP3 and OGG (Vorbis) use lossy compression to reduce file size by discarding audio data. Converting them to WAV cannot restore discarded information. If further editing is required, convert to uncompressed WAV first to avoid repeated lossy encoding, then compress only once at the end.
Increasing the sample rate above the source does not add new high-frequency detail. Using the source settings as a baseline avoids unnecessary file growth.
The encoders that can be used differ depending on the browser and OS. If the format does not appear in the conversion candidates, try using a compatible browser.
