- Manually adjust audio sample rates, even up to 192 kHz, depending on input hardware.
- Assign engineering units to your input signals and calibrate external transducers for accurate measurements.
- Save acquired measurement data to CSV, TXT (tab-delimited), or MAT files.
- Save high-resolution analyzer display images to PDF files.
- Retrieve your data files via Files (iCloud Drive), iTunes File Sharing, or through a web browser on another device.

- Level Meter - Overall signal level meter
- Noise Dosimeter
- Data Recorder - Stream up to 8 channels to WAV, AIF, or CAF audio files.
- Stereo Signal Generator
Pro Tools: (Pro Tool Set subscription includes basic and advanced tools)
- Dual-channel System Analyzer (Frequency Response Magnitude/Phase, Phase Delay, Group Delay, Coherence, Impulse Response and Cross-Correlation)
- Room Acoustics Analyzer (T20, T30, T60, nonlinearity, EDT, Early Decay Time, Center Time, Clarity, and Definition in various frequency bands, adjustable Schroeder integration limits)
- MultiTool - Powerful data monitoring and project management (Add up to 2 subtools on iPhone, 6 subtools on iPad Pro with 10.5-inch or larger display, 4 subtools on other iPad models, and save an arbitrary number of different configurations for easy recall at a later time.)
- Multi-channel Audio File Player - Analyze pre-recorded data.
Additional Pro Features:
- Data logging support in the Level Meter, Octave Analyzer, and Noise Dosimeter
- Percentile exceeded sound levels in the Level Meter and Octave Analyzer
- NC, RNC, and NR references curves, NC, SIL, and NR values in the Octave Analyzer
- Payment will be charged to your iTunes Account at the end of the free trial period, unless you have turned off automatic renewal. If the free trial has already expired, payment will be charged at confirmation of subscription purchase.
- Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.

- You may manage your subscriptions and auto-renewal may be turned off by going to your iTunes Account Settings after purchase.
- Any unused portion of the free trial period will be forfeited when you purchase a subscription, where applicable.
- Added support for new screen sizes of iPhone XS Max, iPhone XR, and iPad Pro 11-inch.
- Added 'lbf' and 'N' to available input channel units, to support force measurement with impact hammers.
- The Octave Analyzer and Level Meter now support Leq averaging over 1/8 and whole second intervals, which are akin to the Fast and Slow response times of the Lq levels, respectively. A Max level is also now shown for Leq in the Meter tool and the Octave tool can display an Leq Max secondary level.
- Vertical Autoscale works properly for static data loaded from files and plotted in the FFT, Octave, and DFFT tools.
- The HTTP file server is properly restarted when the app becomes active after having been inactive in the background for some time.
- Cosmetic improvements and minor bug fixes.
Ratings and Reviews
Great audio analysis tools
SignalScope X audio analysis tools offer quite a lot of signal information in exchange for the monthly subscription rate.
With the newest release, Faber Acoustical gives the user even more bang for their buck with the addition of new sound analysis tools such as “RoomScope,” and enhanced file handling capabilities which can be used even without a subscription.
The variety of subscription plans and rates provide pro audio analysis solutions that accommodate any budget.
While this is a great 5-star app, it's way to pricey for me. For less than the cost of a yearly subscription to the advanced tools, I bought a handheld rechargeable digital color oscilloscope that does FFTs, measures voltages, and supports 2 channels simultaneously. Much more versatile without the need for my phone. It may not have all the features this app has, but you gotta draw the line on over-priced software. Maybe if I owned a high-end recording facility...
I've found so many uses for the hand-held scope. And I get free upgrades for life as new features come out. Oh, yeah, it also self-calibrates.
When software is more expensive than a stand-alone device, somethings wrong.
Developer Response ,
We're pleased to hear that you think SignalScope X "is a great 5-star app." We would certainly appreciate your 5-star rating.
Would you be willing to share with us the make and model of the handheld scope you mentioned? Does it offer any functionality that is germane to SignalScope X's Advanced Tool Set or is it more comparable to the Basic Tool Set, which is considerably less expensive?
I’m on board with everyone else. While the app is very full featured, I can’t justify the continuing costs, and rather expensive costs at that. I can go with a one time cost of the very good Studio Six apps for the same cost. And now I just read that the existing Faber apps won’t work next month when iOS 12 is released. Very disappointing. I understand that subscriptions are an attractive model to go after, but you have to evaluate your client base and understand what their pressure points are when it comes to recurring costs. Very disappointed.

We're sorry to hear of your disappointment regarding the cost of SignalScope X. If you feel that the software has value, as you indicated, we would appreciate a star rating that reflects the quality of the app. Certainly, it is not so expensive as to merit a 1-star rating.
Regarding iOS 12, we have been testing our legacy apps on iOS 12 beta releases and have not yet found any compatibility issues, so the idea that they will suddenly stop working when iOS 12 is released is simply untrue. Where did you read that?
