Audio Conversion Best Practices
Choosing the Right Audio Format
Select MP3 for general use and music playback (best compatibility), WAV for professional editing (uncompressed), FLAC for archiving (lossless compression), or AAC for Apple devices (better quality than MP3 at same bitrate).
Optimal Quality Settings
For music, use 320 kbps MP3 or 256 kbps AAC for high quality. For podcasts and voice, 128 kbps is sufficient. Always use 44.1kHz sample rate for music and 48kHz for video sync.
File Size vs Quality Balance
MP3 at 128 kbps offers good quality at small file sizes (~1MB per minute). For premium quality, use 320 kbps (~2.5MB per minute). FLAC provides lossless quality but larger files (~5-8MB per minute).
