The Immersive Audio team has shared a new teaser video of their work on the 737NG CFM Immersion Soundpack V2.
This video preview highlights the current build using the PMDG NGXu built-in sound engine. This means that depending on the altitude your aircraft is at, you will hear the sound levels change. As demonstrated in the video, the higher your altitude, the less you will be able to hear the engine noises. The video above gives you just a flavour of what to expect.
In addition, the new update means you will be able to independently change the volumes of internal engine bass and external engine sound.
The update itself should be released this weekend according to the Facebook post.
