It’s a 3D sound!īut as with everything else in life, there are always choices so we’ve painstakingly researched the marketplace and put six of the most popular binaural microphones under the microscope to help you make an informed purchasing decision and start recording.
If the drummer’s behind you, that’s where you’ll hear him or her on the recording. Imagine yourself in the middle of a jazz quartet recording the performance. Using headphones, this approach to recording and playing music is often described as truly immersive and that’s an accurate definition. You could of course shell out $8,000 on a Neumann KU 100 dummy head, but if that prospect sends your wallet into cardiac arrest then fear not because we’ve bundled together a collection of somewhat more affordable alternatives to satisfy your binaural audio desires and enhance your binaural recordings. Using headphones is the best way to experience the sonic soundstage. The doubling of ear gain is quite apparent and in many cases using the system's eq to take down 4 kHz a few notches helps.We have to say straight off the bat that the purchase of a binaural microphone for 3D audio probably won’t be high on the agenda (or even on the agenda at all) for most performing and recording musicians.īut if you have a hankering to record a performance in 360-degree 3D panoramic binaural audio splendor and then play it back and hear sound exactly as it was recorded, then you need a binaural microphone. I also included Harman Target in the graph for reference. For Unknown Headphone profile, I added the AKG K371's measurements as it's a good representation of the Harman Target. Then I added the measurements of each respective headphones from autoeq repo. I measured GC7 with SXFI in the following scenarios: They do have some preset eqs for various headphone models.
I've recorded the frequency responses of the front channels ( for example from front left speaker to left ear) in REW and it kind of follows the Harman target (when smoothed) with a massive ear gain and bass boost of higher magnitude. They advertising materials indicate that they calculate the transfer functions between each speaker (in a 7.1 system) and ear based on photos you submit. One of such personalized virtual surround sound solutions is Creative's Super X-Fi. I have experienced the double ear gain issue. I'm not too versed in binaural / spatial / 3D /. Harman-Target).īut content that is being post-processed with HRTF simulations (be it generic of personalized) will likely need a linear transfer function, since any influence of the head is already being included in the processing.Īt least that's my current understanding of the topic.
This probably is also caused by how the content in question is created - anything that you create while listening to speakers will result in content that will sound best over speakers (or headphones having similar timbre to speakers, e.g. FacebookMeta's "Reality Labs" department has published a few papers on the topic (search for papers for Isaac Engel et al).Įngel's research seems to point towards a linear (measured linear at the DRP) transfer function of the headphone being preferred for binaural content (vs Harman-esque curves being preferred for stereo content). No, there's nothing inherent about a specific construction type that would make it more suited to binaural content.Īs to " what frequency response should a headphone exhibit in order to be suitable for binaural content", that is actually a great question, and one that is being actively researched in the AR/VR developer community right now.
