SoundMeter updated for iPhone 6S and iOS 9
SoundMeter 8.2 and SoundMeter Pro 4.2 are now available for download on the App Store. Each new version includes proper handling of the built-in microphone on iPhone 6S and iPhone 6S Plus devices and minor changes in iOS 9.
Unfortunately, the new iPhones do not support analog input gain selection for the built-in microphones as previous iPhone models did. The fixed input gain of the iPhone 6S/Plus matches the “Mid” input gain setting in the iPhone 5C, 5S, and 6 models. This means that the peak sound level that can be measured using the built-in microphone of the new iPhones is nominally 116.5 dB. Previous iPhones, on their lowest input gain setting, could measure nominal peak levels of 136 dB.
The SoundMeter apps now allow mixing audio with other apps. This means that it is possible to play music from the Music app while performing measurements with SoundMeter or SoundMeter Pro. It is also possible to mix the output of the signal generator with the audio output from another app.
Also new in each app, when using an iPhone or iPad that has multiple built-in microphones, the unique name of the selected microphone is displayed (e.g. “Bottom Microphone” or “Right Microphone”).
This is my go-to dB metering iOS app. Legit. #TheMixDoctor https://t.co/U4kTMpDfVr
Hi Faber,
I only found a frequency response chart of iPhone3 and 4. I couldn’t find iPhone 5 and 6 input frequency response any where.
I have a feeling that the later model of iPhone may have worse ( not as flat as iPhone 3 or 4). if this is true, how sound meter compensate this high end frequency none linearity.
I’d really appreciate if anyone can help me telling what’s the iphone 6s built-in mic sensitivity. I need to calibrate Sound Meter and couldn’t find this information anywhere.
