Frequently Asked Questions about Audio Converter
What audio formats can I export to?
You can export to 10 formats: MP3 (universal), WAV (lossless studio), M4A (Apple AAC), AAC (streaming ADTS), OGG (open Vorbis), FLAC (lossless compression), OPUS (high-efficiency speech & music), WMA (Windows), AIFF (Apple studio), and AC3 (Dolby Digital).
How does loudness normalization and volume boost work?
EBU R128 loudness normalization balances audio levels dynamically to eliminate quiet sections without clipping peaks. You can also boost volume by +25%, +50%, or +100%.
What are Fade In and Fade Out transitions?
Fade In smoothly ramps up volume from silence at track start, while Fade Out gradually decreases volume at the finish, perfect for ringtones and podcasts.
Are my audio files uploaded to a server?
