Correction: I believe that the output of your B&K power supply is single ended (i.e. 'unbalanced' in audio terms) and the max input voltage specified on most pro audio interface hardware is differential (balanced). So, the +24 dBu max input specified for the devices I mentioned previously would actually be limited to +18…
-
Thanks for the additional info. It looks like your best bet is an audio interface that offers line-level input up to +24 dBu (12.283 Vrms). For example: MOTU UltraLite mk5 RME Fireface UCX II RME ADI-2 Pro FSR BE Reference AD/DA Converter With a suitable USB-C adapter cable, or USB-C hub, you'll be able plug any of these…

We recently published an article on our blog about choosing a measurement microphone. You might get some additional insight relevant to your own needs if you take a look at it. Which Measurement Microphone Should I Use with iPhone, iPad, or Mac?
-
In short, you can use any USB Audio Class-compliant hardware interface with your iPhone. Since you are using a B&K 2807 power supply, you'll want to make sure that you choose an audio interface that supports the range of voltages that your 2807 will produce with your chosen microphone and the acoustic pressure you expect…

@salma31 this is a very old thread. The "3.0 upgrade" referred to dates back to 2009. Apple still does not support discounted upgrades to new app versions for existing customers. As a result, Faber Acoustical now offers a choice between the subscription-based SignalScope X and traditional perpetual license versions (for…

The SoundMeter Pro Apple Watch app is essentially a remote control for the app running on iPhone. It does not use the watch's built-in microphone.

Andy, Thank you for the feedback on the documentation with respect to visual adjustments. For future reference, there's an article on the blog that may also be helpful: How to Manually Adjust the Data Scale in SignalScope If you have a trackpad connected to your Mac, the relevant pinch and touch gestures are generally…

Hi @Andy_P, Thank you for your input on this. This is one of the few features from the older Mac version of SignalScope that haven't yet made it into newer versions. It is something we intend to bring back, although I can't confirm how soon that will happen. Although it wasn't intended for this purpose, there is at least…

Hi Apopp, If your files are on an iPad or iPhone, then you should be able to find them in the built-in Files app. In the Files app, go to Browse and then under Locations select On My iPhone. There, you'll find a list of apps, including whichever version of SignalScope you're using (including SignalScope X or any 2020 or…

I'm glad you're now able to select the Zoom device. I strongly suspect it had something to do with disabling Bluetooth connections. I don't expect disabling WiFi to make any difference. The continuation or completion of the measurement is currently the only indication of triggering. I see how that could be a concern with a…
-
Hi jpatynen, I'm sorry the input device selection isn't working for you. Hopefully, we can get you to a solution, quickly. The problem you have described is slightly different than what we have seen in our own testing of iOS 16/16.1. Are you using the Apple-branded Lightning to USB 3 camera adapter? We have had issues with…

Hi Will, The microphones built into the iPhone will typically have a fairly flat frequency response. However, there are various issues to consider when understanding what you have actually captured with the various iPhone models you mentioned. Much depends on the software used to make the recordings. iOS offers a…

Berry, Thank you for the screenshots and additional explanation. I have confirmed the strange behavior in the Recorder tool and will make sure it gets corrected in the next (free) update. Ben

Berry, but the graphic card does not support metal. Using something like opencore to install versions of macOS on hardware that otherwise wouldn't support it is not supported by any of our apps. It would help if you could send a video screen capture to show exactly what you are observing (i.e. what does 'stuck' mean?). You…
-
Hi Berry74, SignalScope Advanced 2020 supports macOS 10.15 or later and the graphics use Metal for hardware acceleration. I don't believe the Mac mini model 5,1 (Mid 2011) even supports macOS 10.15. It supports up to 10.13.6. The legacy SignalScope Pro 3 is still available on the Mac App Store and supports macOS 10.12 or…

You can perform 1/3 octave measurements with SignalScope Advanced or with SignalScope X and an Advanced Tool Set subscription. You can download SignalScope X and try out any of the subscriptions for free for up to 7 days. Note that if you need to measure percentile-exceeded sound levels in 1/3 octaves or you need…

Hi Steven, Airplay has proven to be quite tricky when used with apps, like SignalScope X, that use both audio input and output, although it generally works as you would expect for apps that support output only. For a time, iOS did not allow Airplay to even be used by apps that support input and output. A few years ago,…

The measurement was unweighted. The mic was placed in a Larson Davis CAL200 calibrator with the calibration level set to 114 dB. The clipping was so clean it appears to be digital clipping. So, the microphone capsule may accommodate sound levels as high as 125, but the UMIK-2 appears to clip the signal digitally before it…
-
SignalScope does not automatically adjust the gain (except to synchronize the two input channels of the UMIK-2 when you manually adjust either of them). It does listen for changes in the gain made in other apps (such as Apple's Audio MIDI Setup), so you might want to be sure that no other app is changing it. The gains on…
-
The units for the trigger threshold match the units of the input channel(s). So, if you are using a UMIK-2, and you have your channel units set to Pa (pascals), then the trigger threshold will be in pascals (and, yes, it will correspond to the Y axis scale in the Oscope). For reference, a threshold of 1 pascal would…

Yes, the Dual FFT analyzer is what you want for transfer function measurements. If you look at the iPhone Tutorials section of our blog, you'll see tutorials for headphone frequency response measurement and loudspeaker impedance measurement. Although they are geared toward specific hardware interfaces, those tutorials can…

I apologize for the confusion. The sample rate cannot be adjusted in SignalScope Basic. That requires the Advanced or Pro version. It can also be adjusted in SignalScope X, regardless of the subscription status. None of our iOS apps will currently allow you to select an FFT length that is a power of 2. Technically, it…
-
In SignalScope X, FFT length is defined by the frequency resolution selected in the FFT Analyzer Options menu, along with the current input device's sample rate. You can adjust the device sample rate in the I/O Configuration menu (accessed by tapping the microphone icon on the left side of SignalScope X's main toolbar).…

Hi Kobs, Of course, I'm sorry to hear that. It's unfortunate that we have received so many negative reviews since our switch to a subscription model for SignalScope and SoundMeter. Many of the reviews are based on misunderstandings and/or unrealistic expectations. Some users thought they would receive free upgrades forever…

SoundMeter X offers 3 averaging times for Leq measurements. The Leq average can be calculated for 1/8 or 1 second, in which case a completely new Leq value is calculated 8 times or 1 time per second, respectively. The third option is to have the average calculated over the entire duration of the measurement, from the time…

swredcam, There appears to be some misunderstanding, here. The original SignalScope for iOS was $24.99 and SoundMeter was $19.99. Currently, all the original functionality of SoundMeter, and more, can be downloaded and used indefinitely for free in SoundMeter X. SignalScope Basic 2020, which far exceeds the original…
-
swredcam, I can certainly understand your disappointment that an app you purchased is not compatible with the current version of iOS. What I don't appreciate is the suggestion that Faber is "trying to extort every last nickel out of their customers." It isn't free to update our apps to work with each new version of iOS. We…
-
No problem. I hope you enjoyed your fishing expedition. Ben

The original SoundMeter won't run on iOS 13 or later. In spite of that, you can still retrieve your data by following the instructions I gave. Your data should still be on your device as long as you haven't deleted SoundMeter from it since you restored from backup. Ben
-
Hi Kangaroo1, I'm glad that SoundMeter has been working well for you and I'm sorry that your iPhone died. If the SoundMeter app was part of the backup, it should have been restored. What happened when you tried to restore it? Once the device backup has been restored, you should be able to retrieve the files in one of the…
