EZ3 is a legacy disk image format developed by E-mu Systems for the Emulator III digital sampler. It serves as a container for instrument banks, digital audio samples, and performance configuration data within the original hardware synthesis environments. As an obsolete binary format designed for specific hardware, it presents no security risks, though integration into modern digital audio workstations necessitates specialized translation utilities or emulator software to access the underlying audio data.
