MP3 (MPEG Audio Layer III) is the most widely used audio format, offering good quality at small file sizes through perceptual coding.
3GPP Audio, compressed audio from mobile phone recordings — stored as audio/3gpp — uses lossy encoding to handle mobile voice recordings, phone memos. Typical file sizes: varies by content.
Reach for MP3 when your priority is music, podcasts, audio streaming — its efficient compression makes sharing fast and storage minimal.
