Why? As mentioned, the H2n is widely used in VR sound. My undergraduate engineering thesis involved assessing how well sounds can be located on the horizontal plane using the Zoom H2n. My Thesis - Localising Sounds with Ambisonics The project was completed after I finished the internship, but basically the filtered method gave more consistent results than the recorded, and is generally a better method of virtual headphone testing. Effectively when you listen to one of these recordings you're hearing the test audio as it would sound on a particular headphone. As with the other method, these recordings are listened to on a single pair of monitor headphones during comparative tests. We worked on another method of virtual testing, the recorded method, which involves recording the test audio played through the physical headphones onto the dummy head. Voxengo's Deconvolver was used to extract the frequency responses from these recordings. To get the transfer functions, we played a sine sweep through each pair of headphones and recorded this with a Neumann KU-100 dummy head mic. Subjects listen to these recordings on a single pair of flat-response monitor headphones, hopefully eliminating any influence the physical attributes of the headphone have on the perceived sound quality. The test stimulus (music, speech etc) is then filtered according to this, effectively altering the sound of the test audio in the same way the physical headphone would. In one virtual method, the filtered method, the transfer functions of each headphone under test are measured. A way to get around this is using a virtual method, where one pair of headphones is used to test many. Getting unbiased results from comparative tests of headphones can be difficult, as impressions of sound quality are skewed by the brand, the price, the look and the feel of the headphones. We designed MUSHRA tests to gauge the spatial quality and overall sound quality of headphones and hence their suitability for VR use. Ambisonic Recording of a PerformanceДЄnother project I worked on was a comparative study of two virtual methods of testing headphones. I derived the equations for this in my engineering thesis.

The code works by matrixing the front left (Lf), front right (Rf), back left (Lb)В and back right (Rb) channels of the H2n recordings (AKA the A-format signals) into the 3 FOA components (AKA the B-format signals): W (omnidirectional component), X (front-back component)В and Y (left-right component).

You can find the code for the plugin on my GitHub, or go to Enda's blog and download the plugin with a manual and sample Reaper project. It was well received and it seems that a good few people are actually using it! The plugin was released to the online spatial audio community through various forums on social media. You'd have to use an Ambisonic encoder to get those back from the FOA files. While Zoom eventually included onboard FOA encoding for the H2n, it didn't afford the flexibility of keeping the 4-channel recordings as a pair of stereo recordings (front and back).

Why is this useful? The Zoom H2n is a popular, affordable and amazing microphone favoured by spatial audio and Ambisonics practitioners worldwide which comes bundled with Google's professional Jump VR camera rig. We Should Do A New Thread For IR Discussion.In 2016, I coded a plugin that converts 4-channel Zoom H2n recordings to horizontal-only First-Order Ambisonics (FOA). Maybe Do Some JS Automation FX For Filtering And Stuff To Get The Pure IR? Maybe I Will Make Some Tutorial About Making IRs From Rooms (But I Will Need My Recording Equipment For That, Which I Will Get Back Somewhen This Week).

But I Haven't Made Any IRs Myself So I Must Admit I Don't Know Anythnig About It.ДЄll I Know Is How To Get The IR From Digital Equipment, Though. I would like to experiment with stupid recordings I would make, in my bathroom for example, or in a very very tight space, just for fun.

And do you need the original 'click', without. When they say that basically, you record a 'click' in a church, so you can create the corresponding IR file, the part I am missing is, how do you transform the original record to the final file. Ok ! I did not have a chance to try, yet.ДЇor some reason I thought that I would need to 'extract' something from this file, before it is usable.
