An MP3 file with a bitrate of and a size of 33
If this same 36-minute recording were encoded at a higher "near-CD" quality of , the file size would jump to approximately 84 MB , nearly 2.5 times larger than your current file.
: At this rate, the file consumes approximately 0.9 MB per minute of audio. This efficiency is why the format became the foundation of early digital music libraries.
