Psychoacoustic Testing – Brüel & Kjær

I find it interesting how psychoacoustic testing has been developing a strong following in product development yet is not widely used in urban planning and environmental management

Psychoacoustic Test Bench Type 5301 is an advanced option to Sound Quality to assist in the tasks of:design and set-up of jury testsconducting jury testsdata collection and statistical processingcalculation of standard metrics on jury test samplesgeneration of combination metricsSubjective TestsFor each subjective test session, a play list and jury answer form are automatically produced. Jury preferences can be collected on-line using a web-based answer form and automatically transferred to an Excel worksheet for statistical and regression analysis. The program provides a fully detailed report score sheet for each jury session and saves the answer forms, play-lists and Excel worksheets for later reference. Psychoacoustic Test Bench supports both Paired Comparison and Semantic Differential tests.Objective TestsThe objective test tool calculates a set of metric values, for the sound samples used in the subjective test, from a set of user-selected metrics. The results are placed in an Excel worksheet for statistical and regression analysis. For binaural samples, left, right and mean values may be calculated.Statistical AnalysisThe statistical analysis function calculates the correlation between the objective and subjective tests. Regression analysis is used to determine and calculate the final combination metric. For validation, it also compares the predicted values from the combination metric to the actual results from the subjective listening tests.

The best VR headsets: The virtual reality race is on

Virtual reality is here – 2016 is the year when the likes of Oculus Rift, PlayStation VR and the HTC Vive take the medium mainstream.

And it’s well on its way.For the uninitiated, VR is an immersive experience in which your head movements are tracked in a three-dimensional world, making it ideally suited to games and even movies.Explained: How does VR actually work?While VR was a non-starter back in the 90s, developers are now creating mind-blowing experiences that look set to revolutionise gaming and entertainment.But what are the best VR headsets and which one should you choose? We’ve put together the definitive selection of the most gob-smackingly awesome devices just waiting to be strapped to your face. Read on for the full list…

Rondo360 | Dysonics

Rondo360 renders all audio formats and file types to our custom 360° MTB (motion-tracked binaural) format for hyper-realistic VR audio playback. Whether your project is new or old, whether it’s Stereo or Ambisonics or 1000 sources, you can open Rondo360 in your DAW, spatialize tracks, and output one immersive MTB file. We’ll also support other output formats like B-format (Ambisonics)

They seem to be aiming at a complete workflow

The microphone however only seems to have capsules on the horizontal so is not recording height information as per standard Ambisonics

Planar Magnetic Microphones

This seems like a very interesting addition to the Ambisonic mic cupboard. It needs NO phantom power. Here is a link for more technical details on how this technology works.

Planar Magnetic Microphones
Think you have a large diaphragm condenser microphone? Not so much anymore! At 100mm diameter Audeze’s new mics give the phrase “large diaphragm” a whole new meaning. Instruments like snare drum, slap bass, triangle, acoustic guitar really come alive with our microphones.

Tetrahedral microphone
Your brain is smarter than you think it is: If the audio does not correlate to the video images, your brain knows this, and your visuals never make that final step towards successful virtual reality. When you see someone talking 20 feet away and 30 degrees to the left in a certain acoustical environment, your brain instinctively knows what it should sound like. It knows if the audio was really recorded in a studio, and the electronic reverb does not match the original acoustical space. So your user never “suspends disbelief.” And you never deliver the complete alternate realm experience. Our VR Tetrahedral mic records all the audio around you and up to about 70 feet away – it also lets you manipulate the audio objects in that space after the fact – you can move objects left/right/up/down/front / back during mixdown. Because it supports the Ambisonics B format, you can easily generate alternate down-mixes to 7.1, 5.1, stereo, etc. This microphone is the only solution like this available today. It’s not just the answer for VR, it also works great for recording of live music.

Finally a complete production/reproduction solution. Now you can achieve more accurate monitoring using Audeze microphones and headphones; the same technology used for recording and monitoring creates a more accurate mix.

Available in:
Mono $995, Stereo $1995, and Tetrahedral $3995 versions.
EQ software plug-in included free of charge, and they work with Pro Tools, Logic, etc.
