The first problem is that
libportaudio is not available in the 64-bit RpiOS.
The deeper problem is that the advice you have been following is perhaps not very good -- I won't say definitely, because I'm not a user of pyaudio, but it smells like it a bit. My major reason for suspecting this is that there is a
python-pyaudio package available in 64 (and 32) -bit, and has been at least since buster and most likely for a long time before that.
Yet the article you link does not mention this even once, which implies the author was not aware and did not have a good understanding of linux package management systems. The python module is
pyaudio, so if it is available in the distro, very likely that is in the package name, and in fact there is a simple logic that can be observed in python package names such that we might assume this package is most likely called
python-pyaudio. But let's just search for pyaudio first:
> apt search pyaudio

Documentation for Python bindings for PortAudio v19
python3-pyaudio/oldstable 0.2.11-1+b2 arm64
Python3 bindings for PortAudio v19
There are a couple more packages in the list returned that I have left off.
It is interesting that these are in
oldstable and not the
stable; this is a buster system so it means that package has been there since stretch, which is going back 4-5 years.1 The version listed here is explicitly for "PortAudio v19", which if we dig into their website a bit reveals that this is the current version.
It is important to understand that if the package manager installs something in its default mode, that software is ready to use. A major purpose of a package management system is that it manages dependencies for you.
There is both a python and python3 package available. Here's more about the latter:

Description: Python3 bindings for PortAudio v19
There are dependencies there including
libportaudio2, which presumably replaced
libportaudio0. Again: You do not have to go through the list of dependencies and install them all one at a time manually. By installing
python-pyaudio, those dependencies will be included.
So, what you should have tried first was just:
sudo apt install python3-pyaudio
Presuming you want the python3 version. I can't promise this does work, but it is not hard to try.
- Meaning it was there when that article was written. This is actually good, since it implies that all the rigmarole there was not because the pyaudio package was broken but because the author was not aware it existed.
