Most mp3s are encoded at 128kb/s... kb/s means kilobytes per second. So these types of files require 128kb for every second of audio.

For stereo mp3's this usually works out to about 1 megabyte per minute. So if your tune is 4 minutes long, count on 4 megabytes

1 megabyte = 1024 kilobytes

1 kilobyte = 1024 bytes

Now, if you are recording from a microphone, you will (hopefully) most likely be recording at much higher bitrates, so those figures will change drastically.
