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.
About AC3 files
AC3 (Audio Coding 3), also known as Dolby Digital, is a multi-channel audio compression format developed by Dolby Laboratories. It efficiently reduces file size while maintaining high sound quality, supporting up to 6 channels (5.1 surround sound). AC3 is widely used in DVDs, Blu-rays, digital TV broadcasts, and home theaters. Though a lossy format, it delivers excellent audio performance for entertainment purposes, though not suitable for professional audio mastering due to its compression.
