Which audio format should you choose?

MP3 plays on almost every phone, car stereo and app, so it is the safest choice for listening and sharing. AAC (often in .m4a files) gives slightly better quality at the same size and is the standard on iPhone. FLAC and WAV keep every detail of the original recording: FLAC compresses without losing quality, while WAV is uncompressed and is preferred by editing software. If you are storing a music collection, keep a lossless copy and make MP3s for everyday listening. Converting an MP3 into FLAC or WAV makes it bigger but does not bring back lost quality.

Bitrate and quality settings

For MP3, 320 kbps is the highest quality, 192 kbps is a good everyday balance, and 64–128 kbps is fine for speech and podcasts. A higher bitrate means a bigger file. A 44.1 kHz sample rate is the CD standard; 48 kHz is common for audio that goes with video.
