Audio Bitrate Calculator
Calculate audio bitrate, file size, duration, and quality metrics entirely in the browser. Supports PCM/WAV, FLAC, ALAC, MP3, AAC, OGG/Vorbis, and Opus. Compute bitrate from sample rate × bit depth × channels (PCM), estimate FLAC/ALAC compression (50–60% of PCM), map lossy quality presets (low/medium/high/voice/music) to typical bitrates, compute file size from bitrate × duration, calculate streaming bandwidth requirement, reverse-calculate required bitrate from target file size, and score quality 0–100. Includes 7 sample rates, 5 bit depths, 4 channel layouts, 7 formats, 5 quality presets, side-by-side format comparison, text/CSV exports, history (localStorage), shareable URL, summary stats. 100% client-side.
