Local conversion competes with other open apps for processor time during this GSM-to-WAV job.
A short GSM sample is quicker to process than a full-length recording.
Compare the WAV duration with the source before publishing.

WAV serves DAWs, editors, podcasts, and production delivery, whereas GSM commonly serves telephony and low-bandwidth voice systems.
For GSM-to-WAV delivery, plan for large files for long recordings.
After leaving GSM, the receiving app must support the streams encoded inside WAV, not only its extension.

GSM to WAV taking too long? Reduce other processor activity and leave the page open until completion.
WAV converted from GSM not opening? Test a compatible player and inspect the output streams.
A WAV extension alone may not be enough; verify the required internal codec.

When does GSM to WAV conversion make sense?

It is useful when GSM media created for compact voice exchange must enter a WAV system designed for editing and interchange.

Where is the GSM source processed?

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

How can I approve WAV converted from GSM?

Test the WAV file in the receiving app and compare duration, channels and loudness with the GSM source.
