Best CUDA book for audio applications

Hello, I am new to the world of GPU CUDA programming. My interests in CUDA relate to using it for audio applications. I was interested in purchasing a book on CUDA and was wondering if there might be one which is particularly well suited for learning how to use it for audio applications? Also are there any other online resources, libraries, etc. that anyone would recommend checking out? Excited to start some cool projects.

Also does anyone know if one can use the VRWorksAudioSDK with NVIDIA GPU Cloud services?

Seems like VRWorksAudioSDK might not be compatible with the cloud services. I was looking for an entry level GPU that is based on the Nvidia Maxwell architecture that would be compatible with older Windows 7 Dell desktop towers. Does anyone have any recommendations? Looking to pick something up relatively cheap that would allow me to play around with the SDK.
