Exporting HEX file name settings

I have a project from someone else and when I compile the Binary File as a .HEX file the file itself compiles correctly, but the naming is strange. The sketch name is dspMusik_2_0_0_0 but the exported file name is dspMusik_2_0_0_0.ino.eightanaloginputs.hex , where is the eightanaloginputs coming from and where are the settings to remove it?

eightanaloginputs is the variant of the board you compiled the .hex file for. The Arduino IDE automatically appends it to the sketch name so that you might be able to differentiate multiple exported binaries compiled for different targets. There are no settings to remove it. You can simply rename the file if you like.
