By default stream 0 (the first audio track, usually the main mix). If your WebM carries commentary, dubs, or descriptive audio on additional tracks, the advanced "audio stream" picker lets you pick 1, 2, 3... explicitly. The track list is shown in the upload preview so you do not pick blind.

If the FLAC format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If FLAC is lossy (MP3, AAC, OGG, Opus), the codec recompresses — at 192 kbps the difference is inaudible for most content; at 96 kbps you may hear cymbals or sibilants softening. The WebM container has no influence on this — only the codec settings matter.

Audio demux + transcode runs much faster than video re-encoding - usually 5-15% of source duration. A 1-hour WebM -> FLAC finishes in 3-9 minutes on the standard pipeline. If the FLAC codec matches the source codec already in the WebM (common for AAC inside MKV / MP4), it is a pure remux and runs in seconds.

Almost always a stream-index mismatch — your WebM had a multi-track audio layout and we extracted the wrong stream (e.g. the silent descriptive audio track instead of the main mix). Re-run with the advanced "audio stream" option set to the right index, or pick "all streams" to extract every track as a separate FLAC file.
