iPad low cut filter on GarageBand audio recorder

A -3dB point was measured at around 250Hz. Lower frequencies than this seem to be greatly attenuated as seen on the Garagebands VU meter. Response at High frequencies was great 3dB at around 20KHz.


On the sampler of GarageBand the LC seems a bit more gentle.


Would the amazing engineers behind iPad and GarageBand add a switch to full bandwidth?


The inherent low cut can be useful for proximity compensation.


Fewer options force creativity, in the meantime one could record on sampler a high note of an instrument and play the low notes on the sampler keyboard. This works even on high pitch oscillators recorded by microphone or direct as on this setup. 10KHz tone recording gave great bass and mid notes as there was some kind of interesting distortion.


Setup:


Test tone CD - Sony D-EJ758CK CD player - Canford red Neutrik impedance converter 1/4in jack - Pleiades K117 - iPad mini
