| other | We've been passionate about 3D sound for quite a long time and set up Blue Ripple Sound in 2008 to turn that passion into reality. We use some maths generally known as "Higher Order Ambisonics", which are fairly well understood in academia and link to some important equations from acoustics. What we've done is take this rather theoretical material, work out a few bits that were missing, and turn the results into simple stuff that people can just use! | https://www.blueripplesound.com/ |
| other | These plugins aren't intended for normal studio use; that is what the O3A plugins are for. Instead, the O7A plugins are for research applications and studios with high-end computer equipment. The O7A plugins use 64 channels in tracks and buses rather than the 16 used by O3A (or the 4 used by 1970s first order ambisonics). This provides very accurate spatial imaging, but makes some quite heavy demands of your hardware. | https://www.blueripplesound.com/ |
| other | For plugin hosting, seventh order ambisonic support has been available in Pro Tools Ultimate since version 2023.6, and Reaper has had 64 channel support for a long time. | https://www.blueripplesound.com/ |

Limitations and open questions
Known constraints and missing evidence from the collected pages.
The collected pages do not mention any competitor products. Evidence gaps include lack of detailed pricing beyond the one-time fee, no customer reviews or ratings, and no explicit security or compliance certifications. Open questions remain about the exact performance characteristics and the status of the 'in flux' project mentioned in the BBC R&D demo S75.
Sources, method, and limitations

This report is based on 15 collected pages from blueripplesound.com, including product pages, news, and update pages. The evidence catalog includes features, pricing, integrations, and change logs. External proof search was performed but only discovered a case study link without content. Limitations: no first-party customer reviews, no detailed documentation pages, and some claims are from news announcements that may be dated.
