Extraction of sound sources is a technique which belongs to our core IP and was a subject of intensive R&D over the past years.

Yes, you can live monitor any of your recordings.

The current version of ZYLIA ZM-1 has 19 microphones and audio is recorded in 48 KHz/24 bit quality. The system records 19 tracks from physical microphones and an arbitrary number of virtual microphones that are defined in software by the user. Each virtual microphone is recorded as a separate track.

​These are software defined microphone beams that can be directed in any position in the 3D space. ZYLIA can detect audio sources through a localization process and steer appropriate virtual microphone beams towards them.

Thanks to our virtual microphone technology, it is possible to set microphone beams in many directions simultaneously. In this way you can record in mono, stereo, 5.1, 5.4.1, 7.1 , 22.2 or in any other arrangement of your liking.

​Yes, the microphone and recording software work without any Internet connection.

With Remote control feature in ZYLIA Studio you are able to control the recording process by using a web browser in your smartphone or tablet. Internet connection is required to use this feature.

No, there is no need to use pre-amps or audio interfaces to record with ZYLIA ZM-1. ZM-1 connects to the computer using a USB cable. The device converts the analog signal to digital itself, so you don't need any additional audio interface. You can choose ZM-1 as your audio device in DAW (you should choose an application which supports at least 19-channels per track e.g Reaper or Ardour) or record in dedicated software - ZYLIA Studio. Our device and software record audio signal with 48 kHz sampling rate and 24-bit depth. Sensitivity of ZM-1 microphones is fixed in order to assure the same gain for all 19 capsules.

Because the ZM-1 is a digital microphone, it doesn't require a preamp, meaning that the ideal gain level from ZYLIA Control Panel should be set at minimum to avoid clipping distortion.
ZYLIA Studio's stereo preview uses Left and Right channels of the ZM-1 with Peak normalization.

Calibration let us better separate tracks and increase their quality by locating positions of all instruments. The calibration process doesn’t influence on RAW 19 channel recording.

ZYLIA Studio monitors all 19 channels in real time. If for one or more capsules it is likely that it is not working properly then user is informed about it by a popup window during the recording or during the startup of application.

Using fewer capsules results in a less accurate representation of the spherical harmonics. Using Reaper or other DAW you can select which channels from a track you can work with, however, this is raw signal without beamforming. On this Link, you can see the positioning of each channel in the cartesian and spherical coordinates systems. https://www.zylia.co/white-paper.html

ZM-1 and ZM-1S are using the internal clock, so it is not possible to synchronize the DAC in output interface and ADC in ZM-1. ZM-1S has an timecode input which can be used for synchronization.

Regarding the Ambisonics results, there may be two main causes of poor elevation perception: the renderer itself and microphone construction (lack of a microphone capsule at the bottom and the tripod stand of the ZM-1). In case you are interested, we will be presenting more on this topic in Engineering Brief at the incoming AES Convention .

Streaming latency depends on the configuration of audio and video codecs that you use. For example, video cameras can introduce their own latency, In order to avoid that you should manually adjust the delay between audio and video in your streaming application. For example in OBS you can do this like this https://streamshark.io/obs-guide/audio-delayIn terms of ambisonics delay it depends on the configuration of your audio buffer in DAW, eg. Reaper. ZYLIA Ambisonics converter introduce itself an algorithmic delay of 512 samples - 10 msyou can find more about streaming with Zylia here https://www.zylia.co/blog/how-to-stream-music-and-audio-to-twitch-youtube-and-facebook-with-zylia-zm-1-microphone or here https://www.zylia.co/blog/how-to-stream-3d-audio-in-binaural-format-with-zylia-zm-1-and-zylia-ambisonics-converter-plugin

For playback sound recorded with Zylia, you can use ZAC to convert to Ambisonics and then convert to atmos format by using ec. O3A DECODING by Blue Ripple Sound. You can also use beamforming to separate sounds from soundfield and then encode mono sounds to atmos format in ec. Pro Tools with Dolby Atmos Production Suite.
