By default stream 0 (the first audio track, usually the main mix). If your WMV 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 AAC format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If AAC 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 WMV container has no influence on this — only the codec settings matter.

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

Almost always a stream-index mismatch — your WMV 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 AAC file.

MP3 plays universally. AAC / M4A plays on Apple and most Android, including factory car stereos from 2014+. OGG / Opus needs a recent player and may not work in older infotainment systems. The advanced device-target dropdown picks the safest AAC codec for the target you select.
