Distance cues that are modelled:\r\n\r\n- distance attenuation down to 0.125m, with large amplification possible (overload triggers compression)\r\n- geometric correction of the levels at each ear [see first graph]\r\n- geometric correction of the azimuth at each ear\r\n- spectral correction (proximity effect and head shadowing/occlusion) [see second graph]\r\n\r\nAll parameter changes are continuously interpolated and should be artifact free. An audio source (440Hz tone) under rapid modulation of distance and azimuth, including 12dB of limiting, is shown in the third graph.\r\n\r\n![nearfield_dcgain](https://user-images.githubusercontent.com/13965157/36572231-5d7ad372-17ef-11e8-9d1c-01f26de6195e.png)\r\n![nearfield_dvf](https://user-images.githubusercontent.com/13965157/36572241-6b7e5700-17ef-11e8-9a08-733ee76b11b0.png)\r\n<img width=\"750\" alt=\"nearfield_tone_test\" src=\"https://user-images.githubusercontent.com/13965157/36572263-90eb3940-17ef-11e8-943a-e85b5b177da1.png\">\r\n"},"comment":{"url":"https://api.github.com/repos/highfidelity/hifi/issues/comments/369029029","html_url":"https://github.com/highfidelity/hifi/pull/12479#issuecomment-369029029","issue_url":"https://api.github.com/repos/highfidelity/hifi/issues/12479","id":369029029,"user":{"login":"hifi-gustavo","id":4554450,"avatar_url":"https://avatars0.githubusercontent.com/u/4554450?v=4","gravatar_id":"","url":"https://api.github.com/users/hifi-gustavo","html_url":"https://github.com/hifi-gustavo","followers_url":"https://api.github.com/users/hifi-gustavo/followers","following_url":"https://api.github.com/users/hifi-gustavo/following{/other_user}","gists_url":"https://api.github.com/users/hifi-gustavo/gists{/gist_id}","starred_url":"https://api.github.com/users/hifi-gustavo/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/hifi-gustavo/subscriptions","organizations_url":"https://api.github.com/users/hifi-gustavo/orgs","repos_url":"https://api.github.com/users/hifi-gustavo/repos","events_url":"https://api.github.com/users/hifi-gustavo/events{/privacy}","received_events_url":"https://api.github.com/users/hifi-gustavo/received_events","type":"User","site_admin":false},"created_at":"2018-02-27T21:17:11Z","updated_at":"2018-02-27T21:17:11Z","author_association":"NONE","body":"Mac OS X build is available at: https://deployment.highfidelity.com/jobs/pr-build/label%3Dmacos/7575/HighFidelity-Beta-PR12479-41ccf6afd8640d6f4547d4f72ce46804caf55267.dmg"}}
