SPAT Revolution only accepts 1st order microphones. Most of the time, ambisonic microphones output A-Format, which is a raw format (not encoded). Accepted microphones are grouped into two groups, defined by the channel order:

• Type I, represented by TSL Soundfield (ST250, ST450, SPS200), Core Sound TetraMic, Sennheiser Ambeo, and Rode NT-SF1 microphone. The channel order is Front Left Up, Front Right Down, Back Left Down, and Back Right Up.
• Type II, represented by DPA-4 microphone and Oktava MK4012. The channel order is Front Left Down, Front Right Up, Back Left Up, Back Right Down.

Note that some recording devices like the Zoom H2n could output B-Format or HOA.

Careful: Selecting a microphone of the dedicated may not be optimum be could be simpler to test. We strongly recommend using the company plugin or software to encode the audio data in B-Format or HOA 1st order AmbiX.

If your microphone is not listed but has the same channel order as the one before, you can use one similar microphone temporarily, and contact us: you can provide information to help us to complete the list.

In the case of HOA, an additional transcoding is required as ‘binaural monitoring’ only works with channel based stream. The transcoder output format is automatically set as soon as it is connected to a ‘binaural monitoring’ block.

If you have audio sources that are already binaural encoded, you won’t be able to decode and spatialize these in SPAT Revolution. In this case, just merge your binaural sources with the binaural room’s output using a sum block.

There are two types of transcoding blocks into SPAT Revolution:

• Input transcoder: it allows to transcode HOA or A-Format inputs into channel-based sources, in order to spatialize them into a room.
• Master transcoder: it allows you to transcode HOA inputs into your monitoring speakers setup.

SPAT Revolution offers different methods of transcoding. To access these settings, just select an input transcoder or an output transcoder item on the Setup page.

You’ll find all details concerning the transcoding parameter in SPAT Revolution documentation – Ambisonic transcoding.
