Audio Converter FAQ

Can I extract audio from a video file?

Yes. Add a video file and choose an audio output such as MP3, WAV, AAC, M4A, Opus, or FLAC. The video track is omitted from the converted file.

Does converting MP3 to WAV or FLAC improve quality?

No. WAV or FLAC can prevent additional loss during later editing, but converting an already lossy MP3 or AAC file cannot restore detail that was removed by the original encoding.

How should I choose bitrate, sample rate, and channels?

Keep the source sample rate and channels when compatibility is the goal. Lower bitrate and mono reduce size for speech, while higher bitrate and stereo retain more detail for music; higher values cannot add quality missing from the source.
