Understanding MP3 and AAC formats
What is MP3?
MP3 is a widely supported lossy audio format. It reduces file size by removing audio data that is less noticeable to most listeners.
最适合： General playback, music libraries, voice notes, podcasts, sharing, and older devices.
What is AAC?
AAC is a lossy audio format used by many phones, browsers, and streaming workflows. It is designed to keep speech and music clear at smaller file sizes.
最适合： Apple devices, mobile playback, online audio, and efficient music or voice files.
Why convert MP3 to AAC?
- Use AAC when you need a smaller or more compatible audio file for playback, sharing, or upload.
- Lossy audio outputs reduce file size by removing data, so keep the original if you may need a higher-quality version later.
- Choose the output format based on where the audio needs to play next, not only on file size.
