Encoding speed depends on the processor available to this tab during this Speex-to-WAV job.
A short Speex sample is quicker to process than a full-length recording.
Check picture, sound, and timing in WAV before removing the source.

WAV serves DAWs, editors, podcasts, and production delivery, whereas Speex commonly serves legacy voice chat and speech archives.
For Speex-to-WAV delivery, plan for large files for long recordings.
After leaving Speex, the receiving app must support the streams encoded inside WAV, not only its extension.

Speex to WAV taking too long? Reduce other processor activity and leave the page open until completion.
WAV converted from Speex not opening? Test a compatible player and inspect the output streams.
Use the receiving app’s documented WAV profile when generic playback succeeds but import fails.

When does Speex to WAV conversion make sense?

It is useful when Speex media created for speech-focused compression must enter a WAV system designed for editing and interchange.

Where is the Speex source processed?

The browser prepares WAV from Speex on this device instead of sending the source to a remote conversion server.
