Marco Manunta from M2tech reacts on a question from a customer.
A few days ago, a customer wrote me to ask my opinion on why he couldn’t hear any difference between an audio file produced at 44.1kHz/16bit and the same file upsampled to 192kHz/24bit. He thought that the upsampling process would improve the sound quality of the file.
