Question 1

Why do VoIP systems need 8kHz 16-bit mono WAV files?

Accepted Answer

Traditional telephone networks operate at 8kHz sample rate. VoIP systems like Asterisk and FreeSWITCH use this standard for compatibility. 16-bit mono avoids real-time transcoding and saves server CPU.

Question 2

Is my audio file uploaded to a server?

Accepted Answer

No. All conversion happens entirely in your browser using the Web Audio API. Your audio files never leave your device.

Question 3

What audio formats can I convert to WAV?

Accepted Answer

You can convert MP3, OGG, FLAC, AAC, M4A, and other formats supported by your browser to WAV with customizable sample rate, bit depth, and channels.

Question 4

Can I convert multiple audio files at once?

Accepted Answer

Yes. You can drop up to 5 audio files at once and convert them all to WAV in a single batch.
