How to get an audio from the simulation of my powertrain like engine sound or shifting sound?

Hallo everyone, I need a big favour from the Community. I am working on the hybrid powertrain development. I use frequently the Matlab/simulink to develop a vehicle model. From that, I want an audio from my real time simulation model. The símulation model which compiles the whole powertrain components like (Engine, gears, Electric motor,acceleration frequency, acoustis from the engine, etc). I need the sound of my engine behaviour and the shifting behaviour between the gears. Is there any special toolboxes are there? or can i integrate the model with some other sound systems? or is there any other posibilities? Please let me know# Thanks in advance
