How does it ensure the best audio quality?

It follows a decision tree that prioritizes lossless formats or direct stream copying (-c:a copy) to prevent transcoding artifacts and quality loss.

Does it require ffmpeg to be installed?

Yes, this skill relies on the Bash tool to execute ffmpeg and ffprobe commands on your local system.

Can I choose which audio track to extract from a multi-stream video?

Absolutely. The skill probes the file first and will ask you to select a specific stream index if multiple audio tracks are detected.

Can I extract just a portion of the audio?

For files longer than an hour, the skill automatically prompts you to decide if you want the full duration or a specific time range.

What audio formats does this skill support?

The skill supports a variety of formats including FLAC for lossless quality, MP3 (VBR and CBR), AAC for mobile/streaming, and WAV for editing, as well as direct stream copying.
