Start with the destination, not the file extension
If you want to listen on your phone or send a passage to someone else, consider storage size and whether their player opens the file. If the audio will enter an editing workflow, check the receiving software’s accepted formats before exporting an entire document in a format you cannot conveniently use.
FolioTone can export completed audio as WAV or M4A. The export format does not change how the model reads the content. A mistaken word in the source still needs a text correction and another generation attempt; changing the file extension cannot turn that sentence into a more accurate reading.
When keeping a WAV makes sense
WAV is useful when you want a recording that can enter audio editing tools or when your workflow calls for PCM audio. The tradeoff is storage: an uncompressed recording can be considerably larger than a compressed listening copy. Check available device space before exporting a long book or several prepared sections.
Do not assume WAV automatically makes a voice sound more natural. The listening experience still depends on the text, selected voice, and audio originally generated. Review the source recording first. Choosing a format is a decision about storing and using the result, rather than correcting the underlying performance after the fact.
When M4A suits everyday listening
M4A can be convenient for retaining several listening copies and moving files because compressed audio can use less space than uncompressed PCM. The actual result depends on duration and encoding. Check your exported file instead of relying on one universal size estimate for every book, passage, or voice you might prepare.
If you plan to share the audio, open it in the kind of app or device the recipient will use. A successful export does not mean every external tool handles the file identically. Keep the filename understandable and include sequence numbers when your content has been divided into multiple listening sections.
Check the exported recording before cleaning up
Listen to the opening, section transitions, and ending of the saved file. Check its duration to avoid sending a short trial by mistake. If you edit it in another application, keep the revised copy under a different name instead of immediately replacing the export you have already checked.
Audio export has Free limits displayed in FolioTone; Pro removes the corresponding limits. In either edition, export after the required audio has finished. Keep the source document until you have confirmed both the recording’s content and your ability to open it again from its saved location.
