ecm(source, destination)

Either the source or the destination has to be provided. Note: a source file can't ends with .ecm, the destination must ends with .ecm

The ECM format allows you to reduce the size of a typical CD image file (BIN, CDI, NRG, CCD, or any other format that uses raw sectors; results may vary).

Parameters:

source - string - The source file. If not provided, the destination path minus the .ecm will be used. destination - string - The destination file. If not provided, the source path plus the .ecm will be used.

Returns:

EventEmitter
