- Stereo is good on a stereo system (2+ drivers).
- 8 bit degrades the audio quality significantly and adds undesirable whitenoise.
- The difference in size is huge. The WAV file takes up almost as 10 times as the MP3 file.
- There is not much difference between 22kHz and 44kHz. - 11kHz doesn't seem to degrade the quality much, but it's not worth downgrading (no s ize difference).

- The quality between these three files are hardly noticeable. It's probably because due to a small sample size, and a very balanced music.
- There is not much high range and low range sound in this audio clip
- The difference in size is huge. The WAV file takes up almost as 10 times as the MP3 file.
