To reproduce:
- Open attached package
- Select the audio file in Project Browser
- In the Audio Preview > observe that the file size is displayed as 168.7 KB
- Change the import settings to "Compressed(OGGVORBIS)" and "Compressed in memory" and set the "Compression kbps" to 192
- In Audio Preview > observe that the file size now has changed to more than 305.4 KB

Actual result: It is unclear for the user what the different file sizes in Audio Import Settings and Audio Preview are representing.
