Supported Audio Formats
Lossy Formats (Smaller Files)
MP3 — The most widely used audio format. Works on every device and platform. Best at 256-320 kbps for quality that rivals CD audio. AAC — Apple's preferred format. Better sound quality than MP3 at the same bitrate. Default for iTunes, Apple Music, and YouTube. OGG — Open-source format used by Spotify and many games. Great compression with solid quality. WMA — Microsoft's audio format. Good for Windows devices and Windows Media Player.
Lossless Formats (Full Quality)
WAV — Uncompressed audio. Perfect quality but large files. Standard for recording studios and professional work. FLAC — Lossless compression. Same quality as WAV at 50-60% of the file size. Popular with audiophiles and music collectors. AIFF — Apple's uncompressed format. Similar to WAV, common in Mac-based audio production. ALAC — Apple Lossless. FLAC-equivalent quality that works with iTunes and Apple devices.
