Speaker/Headphone EQ Curves 2019-12-29 15:50:31 The most obvious difference between high-end and cheap headphones/speakers is the flatness of the frequency response. That said, equalization is very easy to perform in the digital domain nowadays. I've wondered for a while why there isn't a standard machine-readable format for speaker/headphone frequency response curves and a standard way of applying the inverse EQ curve in audio software/operating systems to produce flat frequency response from even cheap speakers/headphones. Is this idea feasible? Are there major downsides I'm overlooking to achieving flat frequency response via digital equalization?One other thing I've noticed is that the frequency response sounds pretty good on even fairly cheap Bluetooth earbuds. I suspect that's because they receive their signal digitally and can apply whatever EQ they want before the DAC, so maybe a version of this is already happening?
