Convert wav to map3

I recorded audio in the past few days, but the files are huge. The mobile phone space is limited to 1 GB, And I suffer from no money.

After searching on the Internet, we can convert wav to the map3 format. We all know that map3 is much smaller. It turns out that this good tool has been around me and we use the built-in "recorder" of the system ", open "start" -->"Program"-->" Entertainment "--->" recorder ".

1. Open a file named "Recording 12.wav" from "file" and notice that the file size is almost 180m.

2. After opening the file, select "file" ---> "Save as". In the pop-up save dialog box, there is a "change" button and click to go to "sound selection ", select "MPEG layer-3" here ".

3. Click OK and save. Then it will take a little time for conversion. Then OK.

4. Check the size. After the conversion, the file is changed to a little more than 7 MB.

How much space can be saved and how much things can be saved.
