Why Convert M4A to EAC3 file?

M4A is a stereo or basic multi-channel audio format, but home theater receivers and surround-sound systems are built to work with dedicated surround formats like EAC3 (Enhanced AC-3). Converting brings your audio into that format, optimized for delivering surround channels efficiently to compatible hardware.

If your original M4A is stereo, converting to EAC3 won't create new surround channels out of nothing — it repackages the existing audio into a format your receiver will recognize, without adding channels the source doesn't have.
