Portaudio Windows ASIO with MSVC

[Chris Share]

Ooops... I forgot about the PA_NO_ASIO definition which needs to be
commented out.

If someone could try this that would be great!

Here's the tutorial:



Portaudio Windows ASIO with MSVC

ASIO is a low latency audio API from Steinberg. To compile an ASIO
application, you must first download the ASIO SDK from Steinberg. You
also need to obtain ASIO drivers for your audio device.

First, #include the portaudio header file (“portaudio.h”) in the project.

Next, add the following ASIO-related .cpp files to the project:

pa_asio.cpp (Portaudio\pa_asio)
asio.cpp (Portaudio\build\msvc\common)
asiodrivers.cpp (Portaudio\build\msvc\host)
asiolist.cpp (Portaudio\build\msvc\host\pc)

Then, add the following Portaudio-related .c files to the project:

pa_allocation.c (Portaudio\src\common)
pa_converters.c (Portaudio\src\common)
pa_cpuload.c (Portaudio\src\common)
pa_dither.c (Portaudio\src\common)
pa_front.c (Portaudio\src\common)
pa_process.c (Portaudio\src\common)
pa_skeleton.c (Portaudio\src\common)
pa_stream.c (Portaudio\src\common)
pa_trace.c (Portaudio\src\common)
pa_win_hostapis.c (Portaudio\src\os\win)
pa_win_util.c (Portaudio\src\os\win)
pa_win_wmme.c (Portaudio\src\hostapi\wmme)
pa_x86_plain_converters.c (Portaudio\src\os\win)

Then, add the following include paths to the project:

portaudio\include
portaudio\src\common
portaudio\build\msvc\common
portaudio\build\msvc\host
portaudio\build\msvc\host\pc

Finally, open the “pa_win_hostapis.c” file and go to line 60. Comment
out the “PA_NO_ASIO” definition.

You should now try compiling the "Portaudio\test\patest_saw.c" file
because it is the simplest of the test files.

Hi

Perhaps nothing is wrong. It is reporting that the device is unavailable.
Perhaps you have more than one ASIO driver installed and the first one is
for a device which isn't connected?

Have you tried compiling pa_devs to see what ASIO devices are listed?

Ross.

Hey

I am new here and I hope that I am posting this in the most applicable thread. My question is quite basic, but here it goes.

I have recently read the Steinberg ASIO API (2.2) and was wondering how PortAudio is related? Are the two completely mutually exclusive or do they perform the same function? Apologies if my question is vague, but I am uncertain about the purpose of each one.

Typically, acquiring data from a sound card requires a host application communicating with a driver that directly accesses the soundcard. Is ASIO the "driver" in this case (as well as Direct Sound, WASAPI, WDMKS and WMME?) where PortAudio is the "host application"?

Thanks for the help.

Perhaps it is time for a diagram of portaudio?

Portaudio live on top of ASIO, which is probably best described as a  
class of drivers though I'm not really an expert on ASIO, so someone  
will probably jump in and say "but it's so much more...". Portaudio  
simplifies and makes audio apps portable to multiple classes of  
hardware drivers, and even simplifies the process of porting to other  
OSes. It also lets you interface with things that look, act and smell  
like audio drivers, but serve other purposes, such as Jack.

Hope that helps.

Attached. Is it more or less accurate? Should I upload it to the wiki  
somewhere (perhaps as a png)? Changes?

The diagram makes it look like PortAudio talk directly to the sound
cards. Also one soundcards can be accessed my multiple audio APIs.

Perhaps it could be layered like this:

Application
     |
PortAudio Common
     |
PortAudio API Interface
    /     \
WMME    ASIO   etc
   \      /
   SoundCard

Excellent points. I'll give it another go. Thanks Phil!

Hi Bjorn

Looking good, I have some suggestions though:

- I'm not sure why some APIs have one star (soundcard) and some have more
than one.. there doesn't seem to be a good reason for this.

- What you've called "Driver Types" are probably best called "Host APIs"
since this is what PA talks to, and the real driver situation is often much
more complicated (an ASIO driver might just be a wrapper for a WDM driver
for example). The arrows from PortAudio should point to the host API, the
full layering is (given WMME as an example)

PortAudio -> WMME (host API) -> Driver (??) -> SoundCard

- The OS is not really part of the layering.. your diagram implies this
because of the way you've put soundcard/driver/os in boxes at the right.

My 2 cents as usual

Cheers

Ross.

Thanks to everyone who helped out with this issue.

It really cleared things up for me.
