Excellent, will give that a try soon. Do you have any rules of thumb for what is considered acceptable/good/bad? Or is that likely to vary based on in the individual setup?Yes you can use STEPs but you can just use ARTA - it has an option to measure distortion inside the program. You have to have 64k FFT and sweep sequence length 64k with selected "center peak of impulse response" once you run measurement go to analysis and go to frequency response and distortion. Be advised - THDs rise with volume. It's generally a rule of thumb to set the 1kHz response of the IEM at 94dB SPL for measurement of THD .
Though I'll probably measure a selection of known iems anyway to give a baseline I can relate to
