The device processor performs decoding and encoding during the job during this WAV-to-Speex job.
Large WAV inputs may take several minutes on older hardware.
Keep the source until the Speex result passes a full playback check.

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

WAV to Speex taking too long? Try a small source first to separate a performance issue from a format issue.
Speex converted from WAV not opening? Test a compatible player and inspect the output streams.
If Speex is rejected, compare its codec and stream settings with the destination specification.

When does WAV to Speex conversion make sense?

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

Where is the WAV source processed?

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

How can I approve Speex converted from WAV?
