Tips for Best Results
MP3 for Sharing
If you need to share audio files online or play them on any device, MP3 is your safest choice.
Quality vs. Size
Higher bitrate means better quality but larger files. 192kbps or higher is recommended for music.
Use Smart Mode
The Smart quality setting automatically uses fast copy mode when possible, or re-encodes for compatibility.
Lossless Formats
Use WAV or FLAC if you plan to edit the audio later. Converting back and forth from MP3 degrades quality.
