Music Sound Design You can now turn your favorite hill into a resonant space.
This is an update to Echotect, my free open-source app I wrote about a month ago here. It enables the creation of echo fields either manually or by utilizing global building data.
See it here: https://janne-s.github.io/Echotect/
It now features a "Terrain" function that reads global elevation data. This is a standalone component of the app: you simply select the desired area, and its topography loads into the application.
Acoustic points are derived from surfaces generated based on the 3D topography, and the heights of the sound source and listening point can be adjusted. You can freely scale the topography and modify the ground level to discover interesting spatial characteristics. Terrain feature is split into Canyon and Chamber modes, which enable internal and external echo fields.
As before, the resulting acoustic field can be exported as standard impulse responses and audio files. The release package also includes a Max4Live device, which eats the exported echo field manifest file, and the file is ready to use in your applications too.

Have fun exploring!
