Lossless (WAV) vs Lossy (MP3, AAC) - **WAV**: Uncompressed linear pulse-code modulation (LPCM). Delivers 100% studio fidelity but produces large file sizes (~10MB per minute). - **MP3**: Psychoacoustic perceptual coding. Removes inaudible sound frequencies to achieve 90% file size reduction with high perceptual clarity. - **M4A (AAC)**: The default recording format for iOS Voice Memos, offering superior frequency retention at low bitrates.
Choosing the Right Bitrate - **128 kbps**: Standard voice notes, spoken lectures, and audiobooks. - **192 kbps**: High quality podcast streams. - **320 kbps**: Studio-grade music listening and DJ master tracks.
