About AAC files
AAC (Advanced Audio Coding) is a highly efficient audio compression format developed by Fraunhofer IIS, AT&T, Dolby, and others. It delivers better sound quality than MP3 at similar bitrates, making it ideal for music streaming, podcasts, and mobile devices. AAC is the default audio format for Apple products (iTunes, iPods, iPhones) and is widely supported across platforms. Its lossy compression reduces file sizes significantly while maintaining excellent audio fidelity, though it's not as universally compatible as MP3.
About EAC3 files
E-AC3 (Enhanced AC-3) is an advanced audio codec developed by Dolby, extending the capabilities of standard AC3. It supports higher bitrates, more audio channels (up to 7.1), and improved compression efficiency while maintaining backward compatibility. E-AC3 is commonly used in Blu-rays, streaming services, and digital broadcasts for immersive surround sound. Though still a lossy format, it offers better audio quality than AC3, particularly for complex soundscapes, making it a preferred choice for high-fidelity home theater systems.

Batch Convert AAC to EAC3 Online

With this SoConvert tool, you can convert multiple AAC files to EAC3 directly in your browser for free. You can also adjust the audio Bitrate during conversion.

Click the Options button in the top-right corner to open the settings panel, where you can customize the output EAC3 audio Bitrate.

Other Settings Explained:

  • Encoding Speed: Choose the encoding speed. Faster speeds result in larger file sizes.
  • Audio Bitrate: Recommended range is 8 – 320 Kbps.
  • Cut Audio: Trim the audio using a start and end time in HH:MM:SS format. For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the audio.

    • Before converting, you can choose a local folder to save the converted EAC3 files. Once an AAC file is successfully converted, it will be automatically saved to your selected directory—no manual download required.
