Matroska Audio
AudioMKA is the Matroska audio suffix. It can carry tracks, chapters and tags, while codec identity is separate. Inspect chapters when an album looks like one track and select the intended language/audio stream. MP3 export does not automatically retain every stream.

Menu labels and support vary by app, OS and version. Preserve the original before making changes.
Troubleshooting by symptom
- Wrong audio: inspect default-track and language selection.
- No chapters: check player support for Matroska features.
- Only one exported stream: inspect the converter’s stream selection.
- Wrong language: inspect default and manually selected audio tracks.
- Extracted audio rejected: compare its codec with reader support.
- Track boundaries lost: inspect chapter/tag preservation separately.
MKA → audio extraction / WAV
- Choose a track and check whether its codec can be extracted without re-encoding.
- For editing, export supported audio and preserve chapter/tag information separately when needed.
- For multiple tracks, verify track number, language and chapters after export.
Extraction differs from transcoding; tracks, chapters and attachments may not all survive.
MKA is an audio container
The suffix does not identify one audio codec; inspect and select the intended track.

Validate audio and chapter migration separately
Check chapter, tag and attachment support as well as audio preservation.
For an MP3 copy, record selected track/settings and retain the MKA source set.

Handling and security
Avoid running attachments and review sharing scope for audio/metadata.
Questions and answers
Always one song?
It can contain several streams or chaptered recordings.
Does renaming add video?
No; it cannot add a missing stream.
Can MP3 retain everything?
Choose audio deliberately and handle chapters separately.
How do I verify the extracted track?
Compare number, language, codec, duration and content and explicitly select the target.
Is extraction always lossless?
Distinguish unchanged encoded-stream extraction from re-encoding.
