The short answer
Select a local video, choose an available audio track and export to MP3, WAV, FLAC, OGG or another supported audio output. A compatible stream-copy operation can avoid re-encoding; format conversion usually cannot.
Choose the source stream
Add the video to Audio Extractor For Free and open Select audio tracks. Pick the language or stream you need. Do not assume the first audio track is always the main soundtrack.
Decide between conversion and a compatible copy
Choose MP3 when your listening device expects MP3. Use WAV when your next editor requests PCM audio, or a supported lossless output when that suits your workflow. A larger WAV does not recover information missing from a lossy source.
Where a compatible audio-stream copy option is available, it can keep the encoded stream without re-encoding. The original codec must fit the chosen output; you cannot get an unchanged AAC stream by selecting MP3. Review the operation shown in the app.
Extract and verify the audio
Choose a separate output folder and start the extraction. Listen to the saved file, confirm the intended stream and check that the duration is right. Keep the video so you can extract a different stream or format later.
Use MP4 to MP3 for a specific conversion, or trim and extract a short audio clip when you do not need the whole soundtrack.
