Smallest audio file: MP3, Ogg, or Wav?

Question

I\'m looking for the smallest type of audio file for some javascript to work smoother.

Answer 1

2019: mp3 is your friend.

Type  | Compression  | Browser Support | Quality                | Size
---------------------------------------------------------------------------
MP3   | Compressed   | Great           | Depends on compression | Small
OGG   | Compressed   | Not so good     | Depends on compression | Smallest
WAV   | Uncompressed | Good            | Best                   | Large

Browser support: mp3, ogg, wav
