Variable Bitrate (VBR) is a method of audio encoding where the bitrate fluctuates throughout a track.

During simpler segments, such as silence or a single instrument, the bitrate drops (sometimes as low as 65 kbps ), saving significant disk space without audible loss. Variable Bitrate (VBR) is a method of audio
In complex segments of a song (like a heavy orchestral swell or a drum solo), the encoder uses a higher bitrate, sometimes reaching 320 kbps , to preserve detail. the encoder uses a higher bitrate
