Affordable Measuring Microphones Shootout – Part-3

This page is the follow up of Part-2, here you will find the outcome of my measurements, pros and cons about the 1/4″ Class 2 electret capsule measuring microphone shootout.

Neutrik 3382 vs iSEMic 725TR
Neutrik 3382 vs iSEMic 725TR

Results and findings; after measuring the three microphones the first what struck me was the recorded SPL deviation between the MicW i436 and the other two microphones (the reference – Neutrik 3382, and the other measured microphone – iSEMic 725TR).
All SPL levels below 85 dB the MicW i436 measured 0.5d dB to 0,6 dB of  scale (comparing to the two other microphones).
At levels above the 85dB the differences gradually did lessen to zero around 94 dB (where it was calibrated).

Below the results of the three 1/4″ Class 2 measurement microphones shootout mentioned earlier in Part-1.

A Neutrik (NTI) 3382 was used as reference.

Equalizer APO

A few months ago I ran into a Windows program called Equalizer APO (beta)  while I was searching on the Internet for a Windows counterpart of the OS X based program Audio Hijack 3.

Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented as an Audio Processing Object (APO) for the system effect infrastructure introduced with Windows Vista.
(APIs like ASIO or WASAPI exclusive mode can not be used)

Affordable Measuring Microphones Shootout – Part-1

Like me most of the audio enthusiasts are interested in measuring their own loudspeakers and/or room. A professional Class 1 measuring microphone could cost € 1000,- or more. Most people have not that much money to spend so what are decent and affordable Class 2 measuring microphones?

I’ve found and tested several 1/4″ Class 2 measuring microphones in the € 20,- to € 200,- range. They have all in common that they can be used with a mobile device (like; iPhone, iPad, Android or Windows mobile phone/tablet), but also with a notebook or PC.

For the tests I’ve used an old Neutrik (NTI) 3382 measuring microphone (with frequency correction files) as reference. The measurements were taken in my living room using a pair of bi-amped Philips VN3100-25 (OEM Stage Accompany Blue Box, SA4525). The distance between the measuring microphones and loudspeaker was set at 0.5 meter and 1 meter distances.

Using MicW i436 with Smaart v7 Di – Part-3.

Follow up of “Using MicW i436 with Smaart v7 Di – Part-2

A couple of weeks ago I finally hooked up the MicW i436 Kit to my MacBook Pro to take some measurements of my loudspeaker set in my living room. I own a set of Philips VN3100-25 active loudspeakers which inhabits the famous Stage Accompany SA8525 Ribbon Compact Driver and a SA1513 woofer,

The SA8525 RCD with its frequency range from 1 kHz to 30 kHz is the ideal driver to test the MicW i436 Kit with Smaart v7 Di.

The MicW i436 (designed primarily for  iPhone, iPad and iPod Touch) uses a 4-conductor 2.5mm phone connector (CTIA/AHJ standard) that fits into any mobile device, notebook or PC with a headphone/mic socket following that standard. For one-channel measurements like SPL measurements the MicW i436 can be hooked up directly to a headphones/mic socket of a notebook, for example a MacBook Pro.
