  • 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, (Quote) 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. (Quote) It would help if you could send a v…
  • Hi Berry74, (Quote) SignalScope Advanced 2020 supports macOS 10.15 or later and the graphics use Metal for hardware acceleration. (Quote) 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 l…
  • 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 m…
  • 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…
  • 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 …
  • 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…
  • 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 axi…
  • 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. Althoug…
  • 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 a…
  • 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 tappin…
  • 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 unrealisti…
  • 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 ave…
  • 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 …
  • 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 custo…
  • (Quote) No problem. I hope you enjoyed your fishing expedition. Ben
  • (Quote) 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 y…
  • Hi Kangaroo1, I'm glad that SoundMeter has been working well for you and I'm sorry that your iPhone died. (Quote) If the SoundMeter app was part of the backup, it should have been restored. What happened when you tried to restore it? Once the dev…
  • Unfortunately, iOS 13 broke compatibility with legacy versions of our apps. End of support for these apps was announced in January, 2018 and they were removed from sale on the App Store in July, 2018. At that time (when iOS 11 was current), we could…
  • The end of support for the legacy version of SignalScope Pro was announced in January of 2018. The final update was published in March, 2018, and the app was removed from sale on the App Store in July, 2018. Faber Acoustical Releases SignalScope X f…
  • According to MicW's current instructions, you should set the device gain to Mid and the device units to FS. Then, set the sensitivity for the input channel according to the value that was written on the sheet that came with your i437L (e.g. 19.9 Pa/…
  • It's true that there are no physical knobs for adjusting the Oscilloscope display. Perhaps, you have already found that if you look in the Display tab of the drawer on the bottom side of the Oscilloscope window, you'll see the software controls for…
  • Hello Martijn, Which MicW model are you using? Which version of SoundMeter? If you are not seeing the option to select between FS and V for the device, that suggests that your MicW is either not connected properly, or that you have the built-in mi…
  • Unfortunately, the i437L presents itself as if it were a standard headset jack. This means that apps like SoundMeter cannot automatically distinguish between an i437L and a standard headset jack. Your approach is correct (i.e. Device Units = FS, Ch…
  • Yes. With those settings, you'll get the average sound level over 20 seconds in each whole or 1/3 octave band, plus an overall (full bandwidth) average level. You can see the overall level by tapping the graph to turn on the cursor.
  • Based on your description, I would recommend that you look in the Octave Analyzer options menu and set Level Type to Leq, turn on Auto Stop, and set the duration to 20 seconds.
  • What would you like to do with averaging?
  • In SignalScope, you'll see an info button (a little 'i' in a circle) on the right side of the toolbar at the top of the screen. Tap that, and then tap on Help.
  • Hi, The Octave analyzer tool (RTA) supports both exponential (Lp) and linear (Leq) averaging of the signal in each whole or 1/3-octave frequency band. For exponential averaging, Fast, Slow, and Impulse time weightings are supported. For linear aver…
  • Steve, If you are trying to perform dual-channel measurements (e.g. frequency or impulse response), I would point you to the tutorial on the blog for reference. Frequency Response Measurement with Electroacoustics Toolbox 3 Why can't you use the o…
