An underground parking is a place where you don't feel safe. A squeaky door, a car in approach or simply someone playing with keys. Once again you will have a lot of possibility with those surround sounds for creating space and depth.
This is an Ambisonics sound effects library - and by using the free SoundField SurroundZone 2
plugin you can convert the B-format files into your preferred format (stereo, 5.0, 5.1, 6.0, 6.1, 7.0 or 7.1 surround). Note: The library also contains ready-made stereo mixdowns for your convenience.
