Inside each Pro II is a matched pair of DPA 4060 lavalier microphones.
3DIO BINAURAL MICROPHONE FREE
The Free Space Pro II is so expensive because of the microphones that it uses. Why Is The Pro II More Expensive If It’s Not As Good? However, with the Free Space capable of recording painfully loud sounds up to 120 dB, this SPL difference is of little importance (unless you want to record jet aircraft taking off). The Pro II can record sounds up to 134 dB without distortion. SPL measures the maximum loudness a microphone can record before distortion occurs. The only advantage the Free Space Pro II has is that it has a higher SPL. In comparison, the Free Space is more sensitive, has quieter performance, and costs less! Takeaways:Īs is clearly shown, the Free Space if capable of recording much quieter sounds with less hiss than the Free Space Pro II. SNR values range from 0 dB to 94 dB with higher values indicating less noise. The specification to look for the signal-to-noise ratio, often abbreviated as SNR. If a microphone makes too much noise, the hissing sound will be very loud and distracting in the final recording. Noise is an extremely important specification when recording quiet sounds. For this reason, noise levels of microphones varies tremendously. However, manufacturers can limit the amount of noise a microphone produces by optimizing the electronic components used for low-noise operation. Since electrons need to move for electronic devices to work, microphones will always produce some amount of noise. This sound is largely produced by electrons moving around in circuits. When microphones are turned on, they produce noise that sounds like hissing static. The factor that sets microphones apart from one other is noise. When it comes to recording quiet sounds, some microphones are far better than others. Continue to the next section to learn more about these specifications. The reason I emphasize this is because recording quiet sounds is very difficult, and certain specifications are very important in determining a microphone’s ability to record such sounds. In any case, the point I want to make here is that the average consumer purchasing a 3Dio microphone is intending to use it to record very quiet sounds, whether that’s the sound of brushing one’s hair, or the sound of a quiet dawn chorus. However, they are also used by nature field recordists and others wanting to record a soundscape as accurately as humans would hear it. Without a doubt, 3Dio microphones are most commonly used by ASMR content creators.
Theoretically, this could be done in post-production with an EQ curve, but using 3D molded human ears is not only easier, it produces better results. The shape of our ears naturally amplifies some frequencies and reduces others. They claim that this achieves the most realistic, binaural sound in comparison to human hearing. Their unique selling point is that their microphones are mounted in hyper-realistic human ears made of silicone. 3Dio is a company who manufactures binaural microphones and accessories.
