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)

Dynamic Range Meter

A couple of months ago I’ve found a very interesting website which fights against the loudness war; Dynamic Range Database.

dr-meter-windowsThe Dynamic Range Database uses a sliding scale from 1 to 20 (1 being the worst, 20 being the best) to rank the dynamic quality of each of the recordings they list. This number represents the difference between the peak decibel level on a recording and the recording’s average loudness.

Dynamic Range Database applies the following descriptors to these ranges:
1-7=bad; 8-13=transition; and 14-20=good.

Evaluation for each album on the website includes the album’s average dynamic range, the track with the weakest dynamic range, and the track with the greatest. The Dynamic Range Database also provides individual dynamic range measurements for each track on the album. Below on this page you find three free downloads to test your own collection of CDs, DVDs, LPs or your music files. You can also share and add your results to the Dynamic Range Database by simply fill in the form and upload your data. Continue reading Dynamic Range Meter

Measurement and display of the Dynamic Rangeas well as splitting the dynamics into whole number values is not without complexity, as we have discovered through the research and development stages of finding this solution.

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.

What I like the most about Pro Audio ?

Many people declare me insane when they see my two Stage Accompany (SA) Blue Box enclosures standing in my living room. They always ask me how my wife feels about these “monsters” taken so much place of our living room.

I know that the WAF (Wife Acceptance Factor) of the SA Blue Box is rather low so many women will prohibit their husbands to place such “monsters” in the living room. Fortunately my wife doesn’t care about the size of the enclosures as long as I’m happy she’s happy.

Finally at last I’ve got the change to listen to a set of Stage Accompany M57 studio monitors (in combination with the new Stage Accompany DS50’s from the SA Digital Series). This was the first time the M57’s were used with DS50 digital amps.

Because other people were also anxious about the M57 and the DS50 I’ve invited them to a listen session in a restaurant called “Pegasus” at Ridderkerk (same Dutch town as the residence of Stage Accompany).
