Quality Context
Lossy compression (like MP3 at 320kbps) removes 'inaudible' data, reducing file size by 5x-10x with minimal perceived quality loss.
Overview
Audio file size depends on bitrate (quality), duration, and compression format. Higher bitrates produce better quality but larger files. MP3, WAV, and FLAC have different compression efficiencies. This calculator helps estimate storage needs for music libraries and recordings.

Pro Tips
Standard CD quality is 44.1 kHz, 16-bit, Stereo.
FLAC is a 'compressed lossless' format, it typically reduces WAV sizes by about 30-50% while keeping the same quality.
VBR (Variable Bitrate) encodes complex parts of audio at higher rates and simple parts at lower rates for efficiency.
High-resolution audio (96kHz / 24-bit) is favored by audiophiles but results in massive storage requirements.
