Hello again
Got my shiny new 3Gs Friday, and tested our audio measurement apps
on it. They run great, but now I see a much steeper low-frequency roll-
off (hi-pass) filter on both the built-in mic and the headset mic. At
least another 12dB / octave, starting at 250Hz, from the looks of it.
I assume it's OK to talk about this product since it is released to
the public.
I'm not very hopeful about the answer to this question, since my guess
would be that it's implemented in hardware, but here goes:
Is there any way to disable the low-frequency roll-off filter on
iPhone 3Gs?
Best regards,
Andrew Smith
