EMD1 is a file format used by Apple GarageBand, Apple's music-creation software for recording, arranging and producing music. It belongs to GarageBand's proprietary data rather than to a widely supported interchange format.
The file can form part of GarageBand's supporting data and may depend on related GarageBand files or projects. GarageBand is available for Apple macOS and Mac OS X. Because EMD1 is not a documented general-purpose format, its contents are intended to be handled by GarageBand.
Open the file on macOS with Apple GarageBand. If it came with a GarageBand project or another set of GarageBand files, keep the files together and open the associated project in GarageBand.
GarageBand may not open an EMD1 file directly if it is an internal support file rather than a standalone document.
There is no standard standalone conversion for an EMD1 file. Use Apple GarageBand to open the related project or data and export the usable musical content to a supported audio format when GarageBand provides that option.
