What Is AAC Format
AAC is a commonly used audio format. It is better than MP3 because it can provide better sound quality at the same bitrate. AAC is a lossy audio compression format. That means it removes some original audio data to reduce the file size. Although some data is removed, the effect is minimal, and we can’t even notice it when listening to the audio.
AAC is widely used on some streaming platforms, like YouTube, Spotify, and Apple Music. It is also supported on both Apple and Android mobile devices.
Why Reduce AAC File Size
Although AAC is a lossy compression format that already shrinks file size, there are still situations where you might need to compress AAC files further. Here are some reasons why you should consider reducing the size of your AAC files:
- Save Storage Space: By reducing AAC file size, you can free up storage space on your devices.
- Accelerate Uploads: Smaller AAC files upload more quickly. Compressed AAC files upload more quickly to various platforms, saving you time.
- Reduce Buffer: Smaller AAC files require less buffering time on streaming platforms, enabling smoother playback even with a poor internet connection.
- Meet Platform Size Limit: Some platforms have strict file size limits for uploads. Reducing the size of your AAC files ensures that they meet these requirements.
