Treble
Treble notes occupy the higher portion of the sound spectrum. Increasing the treble value will raise the levels of the
high sounds in your music files. You can select the amount of treble in your music by selecting various equalizer
options.
VBR
Variable Bit Rate (VBR) encoding converts tracks at a variable rate, using higher bit rate encoding for complex
portions and lower bitrate encoding for pauses in songs.
WMA
Windows Media Audio (WMA) is a compressed audio format created by Microsoft as an alternative to MP3. The WMA
codec offers greater file compression than the MP3 codec, enabling storage of more digital audio tracks in the same
amount of space when compared to MP3s at the same level of quality.
