as pointed out by others, python is just one of the languages for which
Ecasound's ECI API is available. But it was one of the first, so there are
quite a lot of options (plus history) related to it.
There are actually two separate implementations of ECI API for python:
1) native implementation (pyecasound.so)
- built against the Python module API (python.h)
- installed as pyecasound.so
- enabled by passing '--enable-pyecasound=c' to configure
- potentially a bit faster, but depends on python runtime and
major+minor version (needs to be rebuilt if python is upgraded)
2) standalone implementation (ecacontrol.py)
- installed as python scripts -> ecacontrol.py
- installed unless explicitly disable by passing
'--disable-pyecasound' to configure
- forks '/usr/bin/ecasound' on the background and communicates
via pipes to implement the ECI API (e.g. python is running
in separate process context than the ecasound binary)
- no build-time dependency to python
Python applications can use pyeca.py, which provides an automatic fallback
from (1) to (2) if pyecasound.so is not available (or does not work).
As for your question, if the native implementation builds against python3
headers, you should be fine. The standalone implementation has to be
tested at runtime (e.g. if you can pass the unit tests under
ecasound/pyecasound/ with python3 installed, you should be fine).
The standalone implementation is portable in the sense that you can use
it with different python versions. The native implementation has to be
built against a specific python module API (e.g. pythonx.y).
