 DLLs for Windows (32-bit and 64-bit)
 ------------------------------------
 
-The DLLs include all available host APIs, namely WMME, DirectSound, WDM/KS,
-WASAPI and ASIO.  For more informaton about the ASIO SDK see
+There are two sets of DLL files,
+one including the default host APIs,
+namely MME, DirectSound, WDM/KS and WASAPI,
+and another one (`*-asio.dll`) where ASIO is enabled as well.
+For more information about the ASIO SDK see
 http://www.steinberg.net/en/company/developers.html.
 
-The DLLs were created on a Debian GNU/Linux system using [MXE](http://mxe.cc/)
-([this version](https://github.com/mxe/mxe/tree/95649828bc29334d5f9abef2718d49a55d9a5407),
-using `pa_stable_v190700_20210406.tgz`)
-with the following commands (after installing the
-[dependencies](http://mxe.cc/#requirements)):
+dylib for macOS (64-bit, "universal")
+----------------------------------------
 
-    git clone https://github.com/mxe/mxe.git
-    wget http://www.steinberg.net/sdk_downloads/asiosdk2.3.zip
-    export PATH=$(pwd)"/mxe/usr/bin:$PATH"
+The file `libportaudio.dylib` is compatible both
+with Intel (`x86_64`) and with Apple Silicon (`arm64`) CPUs.
 
-Open the file `mxe/src/portaudio.mk` and change
-`--with-winapi=wmme,directx,wdmks,wasapi` to
-`--with-winapi=wmme,directx,wdmks,wasapi,asio` (and make sure to keep the
-backslash at the end of the line).
-To the first line starting with "$(MAKE)", append " EXAMPLES= SELFTESTS=" (without the quotes).
-Delete the 4 lines before the last line (i.e. keep the line with "endef").

-        unzip asiosdk2.3.zip

-A different set of DLLs (compiled with Visual Studio) is available at
-https://github.com/adfernandes/precompiled-portaudio-windows.
-
-dylib for Mac OS X (64-bit)
----------------------------
-
-The dylib was created on a Mac OS X system using XCode.
-The XCode CLI tools were installed with:
-
-    xcode-select --install
-
-The following commands were used for compilation:
-
-    curl -O http://files.portaudio.com/archives/pa_stable_v190700_20210406.tgz
-    tar xvf pa_stable_v190700_20210406.tgz
-    cd portaudio
-    # in configure: replace "-Werror" (just search for it) with "-DNDEBUG"
-    ./configure MACOSX_DEPLOYMENT_TARGET=10.6
-    make
-    cd ..
-    cp portaudio/lib/.libs/libportaudio.2.dylib libportaudio.dylib
+All files were auto-created with Github Actions.
+For all the details, see [the config file](.github/workflows/build-libs.yml).
