COMPARISON BETWEEN MONO, STEREO AND BINAURAL AUDIO FROM AMBISONICS

This video showcases the difference between three sound reproduction techniques – mono, stereo and binaural from Ambisonics. Notice how at the beginning the audio is like a point in the middle, then it gains more spaciousness by changing to stereo, and finally – it surrounds you from every side when it’s binaural. Binaural audio lets you experience the recorded moments so naturally, as if you were there – such realistic reproduction cannot be achieved with standard recording techniques.

Microphone capsules

The 19-capsule ZYLIA ZM-1 microphone array has been equipped with XENSIV™ digital MEMS microphones from German-based Infineon Technologies. With a 69dB signal-to-noise ratio, the capsules deliver a 105dB dynamic range and high output linearity up to 130dB Sound Pressure Level. The application benefits are crystal clear audio signals, extended pick-up distance, and sensitivity to both soft and loud signals – from whispered speech to rock concerts. Matched and constant over-time parameters mean that the microphones do not require re-calibration.
 

Summary of features

  • 69 dB(A) signal-to-noise ratio
  • Below 1 percent distortions at 128 dBSPL (AOP – 130 dBSPL)
  • Digital (PDM) interface with 6 μs group delay at 1 kHz
  • Tight sensitivity (-36 ±1 dB) and phase (± 2 deg) tolerances
  • 28 Hz low-frequency roll-off

Benefits

  • High-fidelity and far-field audio recording
  •  Matched, noise and distortion-free audio signals for advanced audio signal processing
  • Ultra-low group delay for latency-critical applications
  • No analog components required

High-quality Ambisonics audio representation due to digital MEMS microphones
The output of the ZYLIA ZM-1 Ambisonics microphone is not the output of any physical capsule but the output of the b-format. That is a combination of signals from all microphone arrays microphones and the quality of DSP behind it. It is crucial that all microphone capsules have exactly the same sensitivity parameters and do not change over time.

No need for ZYLIA ZM-1 microphone re-calibration
Digital MEMS microphones keep their parameters, such as sensitivity, over time. Therefore, usage of Infineon XENSIV™ MEMS meets the requirements of high-quality output Ambisonics signal.

Matched sensitivity parameters
All Zylia microphone arrays are calibrated in an anechoic chamber using a reference microphone and loudspeaker. Based on these measurements, the sensitivity of 19 microphone capsules is corrected to match the same value +/-0.1 dB. Moreover, calibration data are stored on internal memory inside ZYLIA ZM-1.

Ambisonics filters and B-Format
Based on anechoic measurements, dedicated filters are created that are used to generate b-format (Ambisonics) files. There are around 1000 measurement points during this procedure. Those filters are included in ZYLIA Ambisonics converters, plugins and applications.

Comparison to electret or condenser-based microphone arrays
Therefore, the advantage to other microphone arrays based on electret or condenser microphones is that there is no need to calibrate ZM-1; it is already calibrated. If just one of the microphone capsules changes its parameters over time (sensitivity), the recordings will be distorted with additional noise. Therefore, Electret or condenser-based microphone array has to be recalibrated every 2-3 months. Re-calibration is not needed with ZYLIA ZM-1. All microphones are calibrated before shipping to customers with a maximum sensitivity variance of 0.1 dB.

Digital MEMS vs. analog circuits
Infineon digital MEMS used in ZYLIA ZM-1 does not contain analog components. Therefore, they do not introduce any additional noise. In the case of electret or condenser microphones, there is a need to use a preamplifier and analog-to-digital converter. Therefore, the total Signal to Noise (SNR) parameter is a sum of the microphone, pre-amplifier, and ADC. These components can also variable SNR over time or be influenced by temperature. Digital MEMS used in ZYLIA ZM-1 always provide the highest possible SNR.

High-order spatial and Ambisonics audio for binaural recordings
ZYLIA ZM-1 is a 3rd Ambisonics microphone due to 19 capsules. Therefore, it is possible to downscale it to 2nd or 1st order. However, in the case of binaural recordings, a high order of Ambisonics is a must. The higher, the better. Ambisonics order is responsible for the spatial resolution and the overall quality of produced binaural audio.

ZYLIA ZM-1S

ZYLIA ZM-1S AMBISONICS MICROPHONE ARRAY

The 3rd order Ambisonics microphone array with 19 calibrated capsules (MEMS sensors), high-end 24-bit recording resolution and timecode input channel allowing for synchronization of multiple ZM-1S microphones ZYLIA ZM-1S as well as other devices connected to the recording systems such as video cameras.

Timecode input

It allows for the synchronization of multiple ZM-1S microphones as well as other devices connected to the recording systems such as video cameras.
Timecode input specification:
> Can be controlled by an external timecode signal
> Audio line input
   > Full-Scale voltage input (single-ended): 2.1 VRMS
   > ADC sampling rate: 48 kHz
   > ADC bit resolution: 24 bit
Timecode support: 
> SMPTE Timecode Rates: 23.98, 24, 25, 29.97, 29.97DF and 30 FPS
> General audio

Support for multiple ZM-1S recording system (ZYLIA 6DoF VR/AR set)

ZM-1S contains a dedicated chip that allows for the connection of multiple ZM-1S through the USB interface in a single computer. That is, signals from multiple ZM-1S microphones can be aggregated and streamed through a single USB interface. It is possible to connect around 20 ZM-1S to a single USB 2.0 interface. However, if a computer has more USB controllers then it is possible to aggregate more signals. In that case, the only limit for connecting ZM-1S is hard disk speed. For modern SSD disks, it should be possible to record more than 150 ZM-1S connected to a single computer.
Typically, each USB port on laptops has a dedicated USB controller.
