anyone else out there trying to record audio in GarageBand on iphone or ipad using the line input and having the same issue - low frequencies are dropped?
Apple, please put this in an update to GarageBand soon. This would make it the perfect recording app for iOS. It should be a simple switch to utilize the "measurement mode" that was made available in iOS 6 and bypass the low-cut filter.
Without this feature, you are forced to use a digital input to the 30-pin or lighting connector. Which does probably have better quality, but I have a mix of people and devices, some have the 30-pin, some have lightning. And the iPhones don't support the camera connection kit to plugin a USB device. And I really like being able to plugin a simple cable vs having a bunch of dongles.
