What quality is the audio extracted by the Audio File Separator?

This tool extracts the maximum quality audio available from the original source video file, subject to your output file choice. For best results, we recommend extracting audio in .wav file format.

Of course, the quality of the audio output ultimately depends on the quality of the source - the video file input. In general, video files produced with lossless compression, such as .avi and .wmv, often give a better result than video files with lossy compression, such as .mp4 and .mov.
