About this project
Why 3D sound?
Human hearing is binaural, which by definition means used with both ears. Our ears and brain enable us to recognize 3D cues relating to location, distance, and movement of sound in 3D space. Hence, we naturally hear in 3D sound.
Why a CrispMic™–3D?
Sound recorded by the CrispMic–3D microphone preserves 3D cues so the listener can hear sound the way our human ears hear it. The 3D microphone has multiple microphone elements to work as “ears” and a DSP processor to work as the “brain”. It is the first portable microphone that can record in binaural, stereo, and mono sound simultaneously in one device. When you listen to the recorded audio with headphones, you will experience 3D/binaural sound. When you listen with two loudspeakers, you will hear stereo sound.
The CrispMic–3D has a standard USB interface and plugs into a laptop, computer, or tablet. You can record any audio sounds and easily save them to your laptop as .WAV files. The binaural sound is saved in stereo sound format. You don't need to install any software.

The hardware design of PCB is complete (pictured). DSP algorithms, software, and the PCB drives have been developed.
Most of the R&D has been done. With your support, we will conduct an additional round of model parameter measurement to support wider frequency bands for professional music recording.
We are at the concept stage with our industrial design (pictured with a third party mini stand showing a possible setup scenario). The enclosure design will be iterated and finalized.
With your backing, we will finish product development and industrial design. Our suppliers and manufacturers have been selected, and we will place our orders as soon as final quantities are known.
- Back our project: We are excited about our CrispMic–3D microphone, and we really think you will be too. We want everyone to experience and enjoy recording and listening to 3D sound.
- Send us your suggestions: We want to know how we can make our 3D microphone better. Tell us how you plan to use it, so we can consider your needs as we finalize the design.

Risks and challenges
Design Risks: We have iterated the PCB design multiple times and solved the major mechanical, electrical, and acoustic issues. We expect to have one or two more industrial design iterations before going into production.
Manufacturing Risks: We have been working with several manufacturers for a number of years on other products (www.crispmic.com), and have successfully manufactured through them. Our contract manufacturers can handle large volume orders without encountering delays.
Supply Chain Risks: All our supplier relationships are in place. Our 3D microphone shares many of the components used in our previous CrispMic™ products, For the new components we have initiated supplier relationships. We will place orders as soon as final quantities are known.Learn about accountability on Kickstarter
We have developed software with this functionality called 3D sound synthesis, but it is not offered with this hardware only project. Please contact us for licensing options.
I have other 360 degree microphones, which have very high quality audio sensors for right and left (front and rear). Your device has more sensors but what type are they?
It sounds like your device has two uni-directional microphones. Our 3D microphone has 8 microphone elements which form 8 narrow acoustic beams that provide finer beam directionality. It provides 3D cues by filtering the directional signals with head related transfer functions (HRTF). Overall, it provides 3D (binaural) effects rather than just right and left effect.
This version has been designed with a USB interface only. We can add 3.5mm jack or XLR interfaces if there is enough customer demand.
No, the 3D microphone derives its power from the USB.
No, the 3D microphone will come with preinstalled device drivers.
Yes, the 3D microphone is designed for live recording. Please check with your chat software to determine how it handles stereo microphones.
Yes, we tested it successfully with Ubuntu 10.10.
No, we have no current plans to open source this product. We are open to licensing agreements. We are willing to work with partners on specific versions or embedding the 3D microphone in partner products.
This is a completely different product. The output is stereo binaural signal rather than the CrispMic’s mono signal. Its eight microphones form multiple acoustic beams to provide 360 degree coverage rather than the CrispMic’s fixed beam pattern for front only coverage.
We don’t know. We are relying on this Kickstarter to help fund final development and manufacturing costs.
I am used to having a monitor on the microphone that shows whether there is any clipping taking place. Will there be some sort of LCD display to go with this?
No, the recording level can be controlled by your computer's microphone input selection. You can monitor the clipping with any recording software.
