Hello Ray,

if you need to see more details in the higher frequencies just zoom in and use touch gestures to navigate to the desired range.

I’m using a 4th gen iPad – I can’t seem to display the entire frequency spectrum from 20cps to 20,000cps on any setting. It only displays up to 16,000cps (approx)

The scales are logarithmic: they show dB (SPL or FS) on vertical scale (dB is logarithmic) and frequency (logarithmic) on horizontal scale. And if you export we don’t change this – every exported png or csv has logarithmic scale!

Can I export screens showing logarithmic scale?

For the last couple weeks there are missing vertical bars in the low frequency display on my iPhone. The update of 29 April did not change that. What is the problem? Am I doing something wrong?

At the moment we are offering freqeuncy compensations only for MicW Products. But we are working on cooperations with some other external mics as well – hopefully they will be available very soon. Calibration files are not supported.

Hi Jack,

damit ist die Frequenzgangkompensation für das Messmikrofon i436 von Mic-W gemeint. Sie passt den Frequenzgang dem Mikrofon an und ermöglicht eine direkte Pegelkalibrierung.

In Stereoplay (Ausgabe 04-2013) wird im Artikel Mini-Messlabor (Seite 126) ihr Analyzer app beschrieben. De Autor spricht auch von eine Ergänzung für 8,99. Welche Ergänzung wird hier gemeint?

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.

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
