Frequently asked questions
What's the best format for music?
MP3 at 192-320 kbps or M4A at 192-256 kbps for listening; FLAC or WAV if you need lossless quality.
How do I make a ringtone?
Trim the part you want (under 30 seconds), add a short fade-out and export as M4A for iPhone or MP3 for Android.
What does normalize do?
It adjusts the overall loudness to a standard level (-16 LUFS), so quiet recordings get louder and loud ones don't clip.
