Default OGG bitrate is 192 kbps (transparent for music). Override to 320 kbps (audiophile), 128 kbps (typical podcast), or 96 kbps (voice / smallest file). The choice trades file size against audible fidelity and is exposed in the advanced options before conversion.
װעט איך פֿאַרלירן די אוודיאָ קװאַליטעט װען איך װײַז פֿון WebM צו OGG?
Silent gaps almost always mean the WebM file had a multi-track audio layout (commentary, alternate languages, surround backchannels) and we picked the wrong stream. Use the advanced "audio stream" option to explicitly pick stream 0, 1, etc., or re-mux all streams to a multi-track OGG container if OGG supports it.
