Frequency Response Measurement & Correction
The RAAL requisite SR1a headphone has a bass bump from 50 to 125 Hz, a mild dip in the lower midrange and mostly flat to about 800 Hz. Above 800 Hz there is a rise in frequency response with a +4 dB peak in our ears most sensitive range (~2.1 kHz) giving the headphone a decidedly bright “in your ear” upper midrange characteristic.
Engaging the high-resolution convolution filter produces a ruler flat response, eliminating the “in your ear” upper midrange peak resulting in a neutral sound. The soundstage and depth of field is increased with the lead vocals and instruments “sitting in the pocket” of the mix instead of dominating it.
Bernardo M. C: “One word: WOW! These are excellent! A game changer. I was using the ASR PEQ previously and it is definitely no match for your filters. Truly amazing work on your part, you just managed to make my favorite listening setup even better!”
Alain N’s experience: “After 10 hours of music, I can says that your convolution filters for SR1A are completely unbelievable!”
Burak P: “Your filter is such a gem in audiophile arena :) This kind of DSP processing is future of sound.”
