Answer 1

error: Microsoft Visual C++ 14.0 is required download visual c++ build tools: https://visualstudio.microsoft.com/visual-cpp-build-tools/

Answer 2

https://pypi.org/project/PyAudio/#files

It shows wheels for python 2.7, 3.4, 3.5 & 3.6.. And since you do not have bdist_wheel AND you are on python 3.9, source installation is done.

And because pyaudio has native code parts that need to be compiled (because wheel is not available) - you need to have working Visual Studio installed on your machine. Exactly as ther error message says:
