As a calibration microphone, it is an affordable microphone in terms of price performance. but don't expect a microphone-specific calibration file or a document. because these microphones are uniformly fabricated products. there are no special calibration files. Naturally, it does not come with a calibration file. For this reason, do not waste time searching for calibration files on the internet. Because these reports are specific to the microphone. When you add this file to the measurement program, the program analyzes the measurement made with your microphone according to this calibration file. If you have such a more detailed expectation, I would say take a look at the upper segment counterparts. This is the only difference from its more expensive competitors. If we collect it, it will work clearly. Someone who knows his job can do very good measurement and acoustic calibration.
