What is spatial audio?

Spatializing sound allows audio to carry positional data – front/behind, above/below and left/right. G’Audio’s tools enable the accurate placement of sound anywhere within a 3D environment, creating source direction, distance, depth and movement relative to the listener. The accurate sense of localization becomes remarkable in our six-degrees-of-freedom (6 DOF) settings.

What is GAO format?

GAO is a hyper-real sound format that delivers a superior sense of localization and sound quality compared to existing industry offerings. This proprietary format was developed to guarantee the best sound quality and replication of the mix exactly as it will be heard in the final VR environment. GAO format carries any combination of objects, channels, and Ambisonics, with up to 256 simultaneous audio elements. The exported content in GAO format can be read and reproduced using G’Audio Sol SDK or any players integrating our Sol SDK.

What is G’Audio Works?

G’Audio Works is a spatial audio plug-in for Digital Audio Workstations that empowers creatives to design realistic and immersive entertainment experiences, especially 360° virtual reality cinematic projects. Works enables the placement of sound anywhere within a virtual environment, creating accurate source direction, distance, depth and movement relative to the listener.

What is G’Audio Craft?

G’Audio Craft is an interactive 3D audio plug-in for game engines that applies actual human hearing mechanisms (like HRTF) with groundbreaking algorithms to replicate real-life sound effects in game scenes. It can be integrated into major VR hardware systems including Oculus, HTC Vive and Samsung Gear VR while running on Microsoft Windows, macOS, iOS and Android.

What is G’Audio Sol?

G’Audio Sol is a quality 3D audio renderer SDK available for custom integration into Android, Windows, macOS and iOS apps as well as mobile devices. It is the only renderer that supports G’Audio’s proprietary GAO format, which delivers the industry’s highest quality 3D audio. The reference player G’Player has Sol integrated already and is publicly available.

What do I need to start using G’Audio Works?

G’Audio Works requires MAC OSX 10.10.5 (or later version) with Pro Tools 11.2.0 (or later version). Support for Windows and other Digital Audio Workstations will be added in the near future.

What do I need to start using G’Audio Craft?

What is GWorksSlave?

GWorksSlave is a plug-in you should add to each sound track you want to spatialize. It supports a variety of input audio signals (object, channel, and Ambisonics) and it creates a binaurally rendered signal using the geometrical information of audio sources as well as the user's head orientation.

What is GWorksMaster?

GWorksMaster provides an intuitive graphical interface for users to master the audio signals on a 360° video. It generates the geometrical metadata of the audio source as well as the user's head orientation, and delivers this data to GWorksSlave in order to create a binaurally rendered signal. With GWorksSlave, GWorksMaster provides a binaurally rendered audio signal in real-time during the mastering stage.

How do I spatialize audio sources with G’Audio Works?

After installation, add automation parameters (Azimuth, Elevation, Distance) on the source tracks with GWorksSlave plug-in. Then, change the status of the track to Write, Touch, or Latch. Go to the GWorksMaster plug-in and select the desired audio source from the Track List. Afterwards, write the audio source’s position by dragging your mouse on the video view. Please refer to the user manual for more details.

What kinds of formats does G’Audio Works can export?

There are three ways you can choose to export your audio - FOA, FOA+Stereo, and GAO. FOA is supported in YouTube while FOA+Stereo is supported in Facebook. You can test your final output of these formats after uploading your file on YouTube or Facebook. GAO format, which guarantees the best sound quality and localization, can be played on G’Audio Sol Player or any VR players integrating our Sol SDK.

Is there any tutorial on how to use G’Audio Works?

Yes! Please check out the tutorials on our YouTube channel.

How do I play my 360° video output on an HMD (or G’Player)?

G’Player is currently available for both Gear VR (from Oculus Store) and Cardboard (from Google Play Store). Please make sure to install the appropriate G’Player for your device. Copy and paste your exported video and GAO files with the same name to the “G’Player” folder on your device. Please refer to the G’Player manual on the G’Audio Sol page for more details with images and screenshots.

How do I play my stereoscopic video output on an HMD (or G’Player)?

Please make sure that the G’Player app is installed on your device. Copy and paste your exported video and GAO files with the same name to the “G’Player” folder on your device. Note that you need to add an identifier on your file name based on the video’s stereoscopic types (table below). Please refer to the G’Audio Sol page for more details with images and screenshots.

Problems we’re fixing known issues

GWorksSlave is not automatically loaded onto GWorksMaster.

Applicable for Works 1.0.0 to 1.2.0

This may happen when GWorksMaster is inserted in the first track on the top. Please insert GWorksMaster in the very last track at the bottom. If you already saved a session with the first track having the GWorksMaster, move this track to the bottom and then save the session again. Once you reload the session, all the metadata would be stored.

SupportFig1

ProTools turns off by itself.
Applicable for Works 1.0.0 to 1.2.0

This may occur when

  • Grabber Tool is used in Edit Windows
  • User bounce the files with only GWorksSlaves and no GWorksMaster are inserted
  • [Track Recode Enable] or [Track Input Monitor] are used in the track with a GWorksSlave
Files are not created correctly after exporting.

Applicable for Works 1.0.0 to 1.2.0

This may happen when output path of the track with GWorksSlaves is missing as in the image below. Please check the output paths of the tracks with GWorksSlaves.

SupportFig2

Audio is not in sync with the video.

Applicable for Works 1.0.0 to 1.2.0

This may happen because the start point of the video that is loaded on GWorksMaster is 00:00:00 (beginning of the session). Please note that all your works must be done with the session starting at 00:00:00.

SupportFig3

Volume Automation is not working.

Applicable for Works 1.0.0 to 1.2.0

This happens because the signal flow of G'Audio Works is different from that of Pro Tools. To work around it, you can use an AUX Track instead as in the image below. Please check the user manual or session example for more details.

SupportFig4

Videos are choppy on GWorksMaster.

Applicable for Works 1.0.0 to 1.2.0

The resolution of a video can affect video play and the performance of Pro Tools. It is recommended to encode a high resolution video to a lower resolution for GWorksMaster. You can easily transcode the video into a lower bitrate on Mac OS with the following procedure:

  • Right click on the video file
  • Select Encode Selected Video Files
  • Adjust the Setting to 480p and Encode for Greater compatibility

I’m experiencing latency and choppy sounds in my output.
Applicable for Sol 1.3.2 to 1.4.1

This may happen

  • when G’Player is played via Bluetooth devices.
  • because the performance of G’Player depends on the RAM size and CPU performance of your working device. In this case, latency problems can be eased by decreasing the number of GWorksSlave plugins in your session.
FOA and AAC formats are not played properly.

Applicable for Sol 1.3.2 to 1.4.1

These formats will be supported in the near future. Please sign up for our newsletter to get relevant updates.
