What audio formats can AI text to speech export?

Last checked 2026-08-14

In short

Naadly exports MP3 for video and the web, WAV for further editing, FLAC for archiving, OGG for the web and 8 kHz u-law for telephony, plus an SRT subtitle file timed from the render. MP3 for delivery, WAV or FLAC if anything downstream will process the audio again.

Which format for which job

Format	Use it for
MP3	Video edits, podcasts, the web - final delivery
WAV	Anything that will be edited, mixed or mastered again
FLAC	Archiving a master without paying in size
OGG	Web and game audio where licensing matters
u-law 8 kHz	Phone systems and IVR, which will not accept anything else
SRT	Subtitles timed from the render itself

Encode once, at the end. Rendering to MP3, editing, and exporting to MP3 again is two lossy passes for no reason - work in WAV and compress on the way out.
