WebM fileku pribadi nalika ngekstrak audio?
+
Yes. Uploaded WebM files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AMR are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Mengapa file AMR memiliki celah diam dimana file WebM memiliki suara?
+
Usually the WebM carries more than one audio track and the one that was converted is silent or secondary. The converter picks one audio track automatically, normally the main one, and this page has no setting to choose a different track. If the wrong one comes out, remux the WebM with the track you want first (VLC or ffmpeg can do this) and convert it again.
