This fork will allow you to use the WASAPI device as loopback using PyAudio.
So you can use speakers to record audio ✨
If you want to record sound from speakers in python, then this fork is for you.
PyAudioW(indows|ASAPI)Patch come only with WMME, DirectX and WASAPI support if you need more -> create an issue
The Windows Audio Session API (WASAPI) allows you to use output devices (that support this API) in loopback mode. At the time of release, it was impossible to achieve this using the original version of PyAudio.
Note: Now WASAPI loopback devices are duplicated at the end of the list as virtual devices. That is, to record from speakers, you need to use not just a WASAPI device, but its loopback analogue. All loopback devices are input devices.
Read -> Install -> Enjoy!
pip install PyAudioWPatchWheels are available for Windows, Python 3.{7,8,9,10,11}.
All wheels support APIs: WMME, WASAPI, DirectX(DSound).
With new features:
import pyaudiowpatch as pyaudio
with pyaudio.PyAudio() as p:
# Open PyA manager via context manager
with p.open(...) as stream:
# Open audio stream via context manager
# Do some stuff
...Or in original PyAudio way:
import pyaudiowpatch as pyaudio
p = pyaudio.PyAudio()
stream = p.open(...)
# Do some stuff
...
stream.stop_stream()
stream.close()
# close PyAudio
p.terminate()- The behavior of all standard methods is unchanged
- Added several life-improving methods
- Fixed problem with name encoding
- Ability to record audio from WASAPI loopback devices (see example)
-

-
new features:
- Context manager support, for PyAudio(manager) and Stream classes
- Run
python -m pyaudiowpatchto get list of devices(likeprint_detailed_system_infocall)
- 🆕 Sequential recording from speakers
- Play sine, using 'new context manager'
- Record audio from default speakers
- Simple recording app
- Cross-platform concept (Not example)
The following were taken as a basis:
- PortAudio v19 [8b6d16f26ad660e68a97743842ac29b939f3c0c1]
- PyAudio v0.2.12
- Build PortAudio (using the instructions in the README)
Installpython- run in the PyAudioWPatch directory:
python setup.py install - ???
- Profit.
Also you can build wheels:
pip install cibuildwheel- Run in Cygwin:
./cygwin_cibuildwheel_build.sh
- Get your wheels in the
./wheelhousefolder
PyAudio provides Python bindings for PortAudio v19, the cross-platform audio I/O library. With PyAudio, you can easily use Python to play and record audio on a variety of platforms, such as GNU/Linux, Microsoft Windows, and Apple macOS.
PyAudio is distributed under the MIT License.
See the INSTALLATION file in the source distribution for details. In summary, install PyAudio using pip on most platforms.
python -m pip install pyaudioThis installs the precompiled PyAudio library with PortAudio v19 19.7.0 included. The library is compiled with support for Windows MME API, DirectSound, WASAPI, and WDM-KS. It does not include support for ASIO. If you require support for APIs not included, you will need to compile PortAudio and PyAudio.
Use Homebrew to install the prerequisite portaudio library, then install PyAudio using pip:
brew install portaudio
pip install pyaudioUse the package manager to install PyAudio. For example, on Debian-based systems:
sudo apt install python3-pyaudioAlternatively, if the latest version of PyAudio is not available, install it using pip. Be sure to first install development libraries for portaudio19 and python3.
See the INSTALLATION file.
