SignalScope X 13.1 Adds Support for miniDSP EARS Pro

Hardware, News

Early this year, miniDSP released EARS Pro, a test fixture for headphones and earphones that, unlike the original EARS device, offers standard ear canal simulators (IEC 60318-4) and stereo output channels with a headphone amplifier (when purchased with the optional USB 2×2 audio interface). This makes the EARS Pro a much better device for performing dual-FFT-based frequency response measurements of both headphones and earphones. SignalScope X 13.1 adds specialized support for the EARS Pro test fixture’s USB audio interface and makes it so easy to get up and running with compensated frequency response measurements. When the interface is connected to your device, SignalScope will automatically read the serial number from its unique hardware identifier and download factory-supplied microphone sensitivity and […]

MultiTool, Perpetual License Option Added to SoundMeter X 13

iOS, iPad, iPhone, News

Following a major update to SignalScope X, which brought MultiTool access to all Tool Set license tiers, SoundMeter X version 13 also shares internal perpetual license purchase options in addition to the look and feel of Liquid Glass on iOS 26. SoundMeter X is the successor to the original, and most accurate, sound level meter app for iPhone. What’s New at a Glance New Licensing Options Perpetual Licenses: From its original launch in 2018, SoundMeter X has been subscription-based for licensing pro tools and features. For perpetual licensing (pay once, use indefinitely), we published separate apps (e.g. SoundMeter Pro 2020/2022). One of the downsides to this approach was that there was no option for us to offer discounts on new versions […]

SignalScope XM 13 Is a Free Upgrade for Existing Users

Mac, News

SignalScope XM 13 Is Available Now Version 13 represents a major upgrade, matching the tools and features of the recently released SignalScope X 13. The major difference between the 2 apps is that SignalScope XM is a Mac-only application that can be downloaded outside Apple’s App Store directly from FaberAcoustical.com. Despite the significant upgrades to SignalScope XM 13, existing version 12 licenses work in the new version as well as the old, which makes this a free upgrade for current license holders. Why Choose SignalScope XM vs SignalScope X? SignalScope XM provides a Mac-only perpetual license solution for individuals, schools, and businesses at a reduced cost compared to SignalScope X’s cross-platform licenses. App downloads and license purchases can be made […]

Measured: iPhone 17 Pro microphone frequency response and directivity

Hardware, iOS, iPhone, News

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

Hardware, iPhone

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

Hardware, iPhone, News

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 […]
