Analyzer support

important: if the Analyzer does not show any signal, please make sure that it has access to the built-in microphone here: settings -> privacy -> microphone
The Analyzer is an universal App designed to work smoothly on iPad and iPhone. Due to the different display sizes there’s only one main difference: while the iPad main view provides a frequency and a SPL Meter view on iPhone the SPL Meter view is available only in portrait mode. We integrated an autorotation lock function for the iPhone to prevent unwanted view changes.

Main view

Navigation and zoom are provided using the usual touch gestures:



The frequency view shows frequency over time graphs. An overview:



For accessing the menu respectively the properties of the graphs there are icons in the upper right corner:

mainView_icons@2x Snapshots
The Analyzer offers the possibility to take snapshots of frequency over time graphs (depending on your device up to 14). A snapshot is created if you start a Leq measurement, press the hold button or the snapshot button. Each snapshot has its own bar / line graph, an icon (which represents a live updating miniature of its corresponding graph) and it’s unique color. Touch the icon to save, export, clone, change color or remove the corresponding snapshot.


The workspace is the summary of all snapshots and the actual graph. Touch the workspace icon and save the whole workspace (including color settings), export it, change the background color or remove it for clearing the display.

Save & export

Each snapshot and even whole workspaces can be saved in the Analyzers own proprietary data format. All records are listed in the menu under records. They can be loaded, shared via email or iCloud and exported to images (.png) or text files (.csv). When exporting a workspace to a png file all graph and background colors are preserved while the export of a snapshot creates a black on white picture.


Use thecog wheel in the upper right corner to access the menu. Here you can manage your records, change various settings, visit the store or make use of the sophisticated in-app help.


The left column shows your records. If you select a record a preview appears in the right column. It is zoomable like your main view. If you push the load button the graph shows in your main view. You can delete it, export it to .png or .csv files, send it via mail or move it between local storage (on your iDevice) or iCloud if activated. You can open and share .png and .csv files in appropriate Apps like FileBrowser or Dropbox.


If you want your records available on all your devices you can activate iCloud storage. Go to the iDevice settings -> Analyzer and turn iCloud to on. Now you can move your records between local storage and iCloud storage using the export function!

Audio IO settings

The Analyzer uses either the built-in microphone, an audio source attached to the headset input jack or any suitable USB class-compliant audio hardware attached via the dock connector. The iOS automatically detects which audio input and output are used. If the audio IO route changes the Analyzer automatically blends in the current  audio route.

You can select input and output routing in this menu.

When a class-compliant USB audio interface is attached the Analyzer will work always on channel 1&2, 3-8 are not accessible at the moment. We tested successfully and can recommend: Apogee’s One, Duet and Quartet, the RME Fireface UCX, the Alesis IO dock and the Midiface Audioface II.


The frequency range defines the maximum range of the frequency (horizontal) axis.

A single band can either show the sum of energies of each FFT point between left and right border of the band (summed energy) or the mean over the whole band. This decision is made with the band filter mode setting. In sum mode a pink noise input shows a horizontal line and a white noise input shows a line with 3dB / octave  rise. In average mode a pink noise input shows a 3dB / octave drop and a white noise input shows a horizontal line:

band filter mode_sum_enband filter mode average_en

It is possible to view a normalized spectrum. If the normalization is activated, the level in the frequency view is always normalized to full scale.

The dB range defines the maximum range (dB) of the vertical axis. It is of course only available when normalization is deactivated.

The block size defines the length of the analysis interval.

With the reference frequency you define the “middle” of the frequency scale. Very common for measurements is 1000Hz. We added 440Hz also because this is the “musical” reference (A4).

Window functions

With the window function you can influence the leakage of the FFT. Available are Rectangular, Hamming, Hann, Blackman, Blackman-Harris and Flat Top. For more information on fft & windowing go here.

Here are some properties and usages for the different window functions:

    I want to enter a note and find out what frequency it is how do I do that?

    • dan

      Here’s how you can do it easily: touch the workspace icon in the right upper corner, select caption -> peaks. Now you see lines: the vertical lines show the 3 most prominent frequency peaks (the one with the highest level is the one you’re looking for), the horizontal lines show the corresponding levels.

      Dear Mr,

      I downloaded a while ago Analyzer and purchased an I436 micW mic.
      when i installed this special callibrated feature i need to give there a number from my callibrated i436. which is on the manual .
      this is 5.6mV/Pa.

      My question is ; Is this correct to give 5.6mV/Pa ?,, as i gor a quite low input on the mic . Less even as on my ipad 4 int.mic .

      Thnx for reply ahead .

    Hi DSP Mobile

    I’ve bought the analyzer app and for the most part I’m very pleased with it. There is a couple of issues I would like to address. First of all, it seems that the response button in analyzer mode doesn’t really do anything? Or maybe it’s just that the frame rate of the bars is to low but the result is that it’s difficult to get a good average. The competition analyzer app from onyx3 seems to get it right but lacks many other vital functions.
    Another thing I would like would be to change the overall color scheme of the app.
    Other than that it a really great app that I use every week. 🙂

    With kind regards

      The Analyzer is a combination of SPL Meter and frequency analyzer. The Response button is for selecting the IEC conform SPL Meter response times and don’t affect the frequency display. But we got the idea… Maybe there will be a settings option for adjusting the response of the frequency graphics in a future version.
      We already made the background colors and graph colors user adjustable – so there are only the buttons (which will stay as they are), the font color (we will think about it) and the grid color left… We take this into account when discussing the next improvements!

    Can you suggest a good program settings for most performance to mesure a PA System, I mean ( weighting ? ; bandwidth? scale? band filter mode?and window funtion -i mean best settings of this!
    Best regards Martin

    • dan

      Replied on: 21/04/2013, 23:03

      Hi Martin,

      you should first turn off weighting because this applies the weighting filter curves from SPL measurement to the spectrum. If you’re using pink noise for measurement you should use bandfilter mode “summed”, with white noise “average” – both means you’re seeing a horizontal line as a flat frequency response. If you don’t care about levels and want to compare different snapshots / curves it’s great to use the normalized view – if absolute levels are important you should deactivate normalization. For detecting feedback we built in an automatic peak detector. You can activate it in the frequency view by touching the workspace icon and setting caption to”peaks”. As for the window function: they all work well, Blackman or Blackman Harris are great for mixed signals, flat top is perfect for sinusoidal signals.

      Hello Andres,

      The guy who made the test in the factory wrote down not the transfer factor (mv/Pa) which the App requires but the sensitivity (dB). Your value corresponds to “sensitivity” of 7.0 mv/Pa which is the value you need for Analyzer calibration.

    Hello. Sorry, me again. After restarting the iPhone 5s, it worked. Then I switched to a different audio app (Shazam) to detect a song. Switched out of that and back to your analyzer, it stopped working. It seems I’ve got to restart my iPhone every time I want to use this app?

    • dan

      Replied on: 29/01/2014, 11:08

      Hello Mark,

      this is strange. Concerning audio input the Analyzer should behave as any other App, catching the input stream from the iOS when put to front. It is possible though that other Apps use background audio preventing the Analyzer to get access to the microphone while they are running in background. If the problem continues please make sure to turn off other audio apps (double click the home button and swipe them upwards). And please make sure the Analyzer has access to the microphone (settings -> privacy -> microphone ).

    Speaking of professional , I am not one, so here goes my question:

    I have looked at your Analizer app along with the i436 Omni Measurement Mic & i436 Kit Package

      of course both work fine. But: The Analyzer is much more “mobile” and miniature because it’s working on iPad and iPhone. TrueRTA is a great software. Along with laptop and audio interface and measurement microphone it is a lot of equipment though. True RTA offers a sweep, which analyzer does not at the moment. Analyzer has much more detailed Graphics and resolution far beyond TrueRTA. So it’s your choice in the end – may be both?

    The most recent update – April 9th, has complely broken calibration. Yes I can still calibrate it but it after updating everything shows up about 10db higher than before. I can no longer trust the accuracy of the app. I am using the built-in mic and have calibrated it before with a calibrator. I know it’s not a great mic so it’s not perfect, but if was close-within a few db. Now it is way off. Any idea why this may have happened? Or a way to restore this without having to have the calibration set to -12db? Before it was -2.4. Even at -12 if doesn’t seem as condistent as before….

      Hello Robert,

      please make sure the Analyzer has access to the built-in Microphone. You’ll find this under settings -> privacy -> microphone. Sometimes this is deactivated after an update.

        The app only run in my ipad if i open after restart the ipad, but the second time i try to open the app not work any more until i restart again the ipad.
        Allso the noise generator not work.
        The app take more time than normal to open when not work.

        I have this app long time ago and before it was working very well.

        Please, solve the problem.

    Can you please advise about 2 things:
    1. a class 1 mic which works with Analyzer
    2. a compliant audio interface (preferably 4 inputs) which works with iPad mini retina display. I know Alesis has the new iO Mix with 4 channels input, but it apparently only docks an iPad standard size, not a mini retina

    I e-mailed my test.dspgraph from my iPhone 5s to my Lenovo PC, however ‘this file cannot be previewed because there is no previewer installed for it’.
    Which ‘previewer’ would you reccomend me to install in order to view dspgraph files correctly?
    Thank you, and best regards,

    • dan

      Replied on: 17/08/2014, 00:11

      The *.dspgraph is a data format exclusively used by the Analyzer. Export your data as .csv, then you can open it and get all measurement data into other applications.

    it would be convenient if your software displays the actual value corresponding to the frequency whose level is the highest.
    just above this frequency, for example.
    this would allow a bit more readable.
    could you do this?

    • dan

      Replied on: 13/08/2014, 11:49

      The Analyzer can do this: in frequency view select the workspace icon (the one with the grid) in the upper right corner, choose caption-> peaks.

    iPhone 5s with iOS 8.0.2 and update 2.5 for analyzer from 9/27 applied. Portrait display doesn’t show any level and says -247…

    I checked the settings > privacy and it does have access to the mic.

    Landscape display shows no signal either.

    Great app and I’m sure I am not using it to its full capability!

      Hello Roger,

      there are sometimes issues with iOS and the Audiobus engine. Please try the following:
      – quit the Analyzer and all other audio apps by double pressing home button and up swipe.
      – go to settings -> Analyzer -> privacy -> microphone -> and turn allowance off.
      – start Analyzer again and quit it again.
      – turn allowance for microphone use on again.
      – restart the Analyzer

      It seems a little complicated and stupid but it actually worked on my own 5S – since this procedure it’s running perfectly on it.

      Quit the Analyzer (double hit home button and swish up). Restart Airplay (I did all this successfully with AirServer on my MacBook). Connect your iPhone with your mixer. Restart Analyzer – the signal generator now plays via Airplay.

    I would like to use your app (which I have already purchased) for analyzing a very low noise in the frequenzy range beween 20 an 80 Hz. Which of the microphones that are compatible with your app and that you are offering frequenzy compensation for would you recommend for this purpose?

    • dan

      Replied on: 02/03/2015, 12:04

      For very low frequencies use an omnidirectional measurement mic like i436 or the M372 from Gefell. Set the blokc size to maximum (65536 samples) for getting best low frequency resolution.
