Voyage Audio Spatial Mic User Guide
When working with ambisonics, sometimes the raw capsule signals, pre-encode, are collectively
called
​ A-Format ​ , while encoded signals are called ​ B-Format ​ . Ambisonics encoders, decoders
and processors vary in the expected sequencing of the spatial harmonics and their encoded
level (sometimes called weighting). The two most common are
​ AmbiX ​ and ​ FuMa ​ . Make sure
the expected format for a given ambisonic processor matches the audio being sent to it.
Spatial Mic Converter encodes the raw capsule signals from Spatial mic to second order (9
channels) B-Format. Once in B-Format, audio can be sent to numerous sound crafting plugins.
Here are some that work with Higher Order Ambisonics:
● SSA
● Blue Ripple Sound
● Nosiemakers
● IEM Plugin Suite
● SPARTA
Ambisonics may be
​ decoded ​ to almost any format desired (including channel-based) and
stored in formats like ​ ​ MPEG-H ​ . The most common decoding method for ambisonics is called
binaural, which is played back on stereo headphones. When decoding to binaural a Head
Related Transfer Function (HRTF) is used to approximate how human anatomy affects spatial
perception. For example, how does the frequency response of a single sound source change as
you rotate your head in front of it? An HRTF aims to take this into account.
Ambisonics moves us beyond what has been possible with channel based formats, enabling
applications in Augmented and Virtual Reality, music production, broadcasting and immersive
environments. While ambisonics can be used in nearly any type of audio production, adoption is
becoming more widespread. Here are some useful resources:
