SignalScope X version 13 is coming soon and it’s bringing added value to all 3 tool set tiers–Basic, Advanced, and Pro. Along with the release of the major software upgrade, the price for each monthly and annual subscription will be increasing on May 11, 2026. Any existing subscriptions will stay at their current renewal price, so if you would like to save on a subscription, make sure you have an active subscription before the 11th of May. If you already have an active subscription, you don’t need to do anything and your subscription will continue at its current lower price. The subscription pricing will change as follows: Current Subscription Pricing preserved after the change for existing subscriptions Tier Interval Price […]

Measured: iPhone 17 Pro microphone frequency response and directivity
Frequency Response I measured the frequency response of the iPhone 17 Pro microphone by positioning a lab-grade reference microphone (PCB model 378B02) approximately 1mm away from the phone (facing the mic) in our anechoic chamber. The reference mic was connected directly to input 1 of a model 485B39 dual channel USB interface. The iPhone microphone signal was routed directly to a USB-C to 3.5mm headphone adapter using SignalScope’s audio play through function (with measurement mode enabled) and from there to input 2 of the 485B39. The response between the 2 microphones was measured with SignalScope’s Dual FFT Analyzer (on a Mac) with the microphones facing toward and away from a loudspeaker which was generating a swept sine excitation signal. The […]

Measured: iPhone 16 Pro microphone frequency response and directivity
Frequency Response In order to measure the frequency response of the iPhone 16 Pro’s microphone, a lab-grade reference microphone (PCB model 378B02 1/2-inch pre-polarized free-field condenser microphone) was positioned facing the iPhone mic approximately 1mm away from the phone within our anechoic chamber. The speaker was behind the PCB mic, facing the iPhone. Both microphone signals were fed into a 485B39 USB stereo ICP signal conditioner and the response of the iPhone relative to the reference mic was measured using SignalScope’s Dual FFT Analyzer. Then, the iPhone and PCB mic were rotated 180 degrees, keeping the same orientation and position relative to each other, and the response was measured again. The 2 resulting frequency response measurements were averaged. Each averaged […]

Measured: iPhone 15 Pro Max microphone frequency response and directivity
In the early days of the iPhone app store, I posted frequency response measurements of some iPhone microphones, including before and after certain iOS updates. This post represents the beginning of a new effort to measure the performance characteristics of iPhone microphones. Similar to the recent post on the Vision Pro microphone, two important metrics will be frequency response (magnitude) as well as the directional response of the primary (bottom) iPhone microphone. Frequency Response In order to measure the frequency response of the iPhone’s microphone, a lab-grade reference microphone (PCB model 378B02 1/2-inch pre-polarized free-field condenser microphone) was positioned facing the iPhone mic approximately 1 mm away from it. The speaker was behind the PCB mic, facing the iPhone. Both […]

With the release of SoundMeter X and SoundMeter Pro 2022, version 12.5, SoundMeter’s companion app for Apple Watch has been completely re-written for better performance and improved support for newer versions of watchOS. In addition to sporting modernized software code, the SoundMeter watch app includes an interface for the Max Levels tool and adds max and peak levels to the sound level meter display. It should be noted that the SoundMeter watch app serves as a remote control for the corresponding app running on the iPhone–it doesn’t analyze or process any signals coming directly from the watch’s built-in microphone. On iPhone and iPad, SoundMeter 12.5 offers improved handling of data and audio files. On newer versions of iOS, external files […]

Measured: Apple Vision Pro microphone directivity and frequency response
Since SignalScope is available on Apple Vision Pro, it is important to understand the behavior of the Vision Pro’s built-in microphone to make the most of it. Although Apple states that the Vision Pro actually has a “Six-mic array with directional beamforming,” SignalScope only has access to one of these microphones–
