WhatsMyBitrate is a powerful command-line tool for analyzing audio files in bulk. It provides detailed quality metrics, estimates perceptual quality based on spectral analysis, and generates spectrograms for visual inspection. By processing entire directories recursively with multi-threading, it's an efficient solution for managing and verifying large audio collections.
The script supports a wide variety of lossy and lossless audio formats, including MP3, FLAC, WAV, AAC, M4A, and more.
*Note: On Windows cmd, glob patterns like .mp3 are not automatically expanded. Use -a or -t instead.
