WMV ka AAC FAQ Konversi
How do I extract just the audio track from WMV as AAC?
+
Upload the WMV file and the converter demuxes the audio stream from the WMV container, then transcodes it into AAC. Video frames are discarded — no second video pass, no quality loss beyond what the AAC codec itself introduces.
Which audio track gets extracted when my WMV has several?
+
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.
What bitrate does the AAC file use?
+
Default AAC bitrate is 192 kbps (transparent for music to most ears). Override to 320 kbps for audiophile output, or 96-128 kbps for voice / podcast where the smaller file is the priority. Lossless AAC targets (WAV, FLAC) ignore the bitrate setting and keep every sample.
Will going from WMV to AAC reduce my audio quality?
+
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.
Does the extracted AAC keep the WMV sample rate?
+
By default yes — 48 kHz WMV audio becomes 48 kHz AAC audio, 44.1 kHz becomes 44.1 kHz. If you need to downsample for compatibility (e.g. 96 kHz studio masters to 44.1 kHz CD-quality AAC) the sample-rate dropdown does this with high-quality resampling.
Can I batch-extract AAC audio from a folder of WMV files?
+
Yes — drop a folder of WMV files into the upload zone and we run extraction in parallel. Premium gets more parallel workers; on a 100-file batch (typical music-video collection) this is the difference between 90 seconds and 8 minutes.
How long does extracting AAC from a 1-hour WMV take?
+
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.
Will the AAC file carry title / artist / album tags?
+
If the WMV file stores stream metadata (artist, title, album), we copy those fields into the AAC container where the format supports tags. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC / M4A), RIFF INFO (WAV) are all written. Untagged WMV produces untagged AAC — use Mp3tag or Picard post-export to enrich.
Is my WMV private during audio extraction?
+
Yes — same privacy model as every conversion. Source WMV and output AAC are processed in isolated workers and deleted within minutes. We never play, store, or share content. See /privacy/.
Why does my AAC have silent gaps or wrong audio?
+
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.
Can the AAC extraction be stereo, mono, or 5.1?
+
Channel layout follows the WMV by default: a 5.1 WMV audio stream produces a 5.1 AAC where the codec supports it (AAC, FLAC, OGG, Opus). The channel-downmix option forces stereo or mono — useful for podcast workflow or compatibility with mono-only Bluetooth speakers.
Will the extracted AAC play on iPhone / Android / car stereo?
+
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.
