Thank you for the additional info. The fact that the i437L is working rules out some possibilities (like mic access being disallowed in the Mac's Privacy & Security settings). I just tested things out with an i436 mic and I found that if you reduce the gain all the way in the Audio MIDI Setup app, the Mute will…

Hi @korim, Since the version of SoundMeter you purchased is so old, you would need to run it on an iPhone with iOS 12 or older (which you can still do if you have such a device). The good news is that you can download SoundMeter X for free and it offers all the functionality of the original SoundMeter for free.

@crawford, Which version of SignalScope Pro you are running? Which operating system are you running it on? On which device (Mac, iPhone, iPad, which model)? The gain setting should be set according to your specific needs. Depending on the specific hardware you are using, a lower gain (-24 dB) should allow the mic to…

At present, the Level Meter only supports a single channel at a time. However, you can select 4 channels in the Octave Analyzer which will measure the same quantities as the Level Meter, plus spectral data. You could run the Octave Analyzer and the Recorder at the same time in the MultiTool. This requires that your 4…

The differences in measured levels can be due to a number of factors, including microphone frequency response, the acoustical environment in which the measurements are made, the microphone positions within that environment, the nature of the sound being measured, etc. I'm not sure what this means. Perhaps, you could…

Glad it's working for you!

Your units are set up just fine (Pa/FS). FS stands for 'full-scale' and is just a relative value that allows us to convert real-world (analog) values to (digital) values that the software can use. Since you have your own calibrator, you can ignore the sensitivity provided by the manufacturer. In the input channel…
-
If you are measuring ambient levels that are clearly wrong, that suggests an incorrect calibration. Please make sure that your units are correct for the input channel and try calibrating again. You will want to perform your calibration on the input channel, not on the input device. In this case, it may not matter what your…

I assume that you are referring to the MicW i436. I recommend that you read How do I calibrate my microphone with SignalScope or SoundMeter? on our blog. It explains the units associated with microphone input calibration, as well as the calibration process. Not necessarily, but you can. In any case, you need a Lightning to…

You have a couple options in SignalScope X, depending on what kind of analysis you are trying to perform. If you are measuring an acoustic response (frequency response or impulse response) with an impact hammer, then the Dual FFT Analyzer tool is what you need (requires Pro Tool Set subscription). The Dual FFT Analyzer…

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…
