Converts between audio bitrates (kbps) and estimates file sizes for different formats and durations.

公式

MB

bitrate (kbps) × duration (s) / 8000 — bitrate (kbps) × duration (s) / 8000

ステップバイステップガイド

1. 1File size (MB) = bitrate (kbps) × duration (s) / 8000
2. 2Higher bitrate = better quality but larger file
3. 3Lossless formats have variable bitrate based on content
