FAQ

A: CAF stands for Apple Core Audio Format. It is a container format used by Apple to store and transmit digital audio data, commonly found in GarageBand, Logic, audio asset libraries, and some system audio scenarios.

A: OGG is suitable for web publishing, game assets, voice resources, and cross-platform playback. After converting CAF to OGG, the file size is usually easier to control and the audio is easier to use in more workflows.

A: Vorbis is suitable for music, sound effects, and general OGG files; Opus is suitable for speech, podcasts, small audio files, and real-time audio scenarios. If you’re not sure, you can first convert using the default Vorbis quality 4.

A: By default, the original file name is retained and only the extension is changed to .ogg. If multiple files have duplicate names after conversion, the tool will automatically add a number to the file name to prevent results from overwriting each other.

A: No. Audio reading, conversion, preview, and packaging are all completed on the current device. CAF files are not uploaded to the server.

A: The interface only shows the first 20 files for review, and files not shown are indicated by a count. After conversion starts, all selected CAF files will be processed, and the downloaded ZIP will also include all successful results.

Answer: Common causes include file corruption, the CAF using an encoding not supported by the current transcoding core, insufficient memory due to an excessively large file, or an abnormal audio track. We recommend testing with a smaller file first, or processing large files in batches.
