FAQ

For spoken content like podcasts and audiobooks, 128 kbps provides clear speech with small file sizes. For music, 192 kbps offers good quality for casual listening, while 256 kbps delivers near-CD quality. Use 320 kbps (maximum MP3 bitrate) only when audio quality is paramount and file size isn't a concern, such as for DJ sets or archival purposes.

MP3 is a lossy format that removes audio frequencies less perceptible to human hearing, resulting in smaller files with some quality trade-off. However, at 256-320 kbps, most listeners cannot distinguish MP3 from lossless formats. Converting from lossless formats (FLAC, WAV) to high-bitrate MP3 (256+ kbps) preserves excellent quality for everyday listening.
