Figure 3-20. Waveform of the track
You will be presented with an options dialog similar to Figure 3-21. Select the
lowest quality and click OK. Vorbis is a form of Variable Bit Rate (VBR)
encoding. VBR will use different bit rates throughout the track, depending on the
complexity of the audio for each segment. This can potentially produce a very
small file with reasonable quality as compared to a file encoded at a constant
bitrate with the same or less quality but a much bigger file size due to the
complexity of the audio.

The result of this encoding should be an audio track that should sound similar to
the original WAV file but with a file size less than 3 MB. The result from the test
track used for this topic when encoding in OGG's lowest quality setting is a file
size of 2.5 MB with no noticeable difference in sound quality.
