kandi X-RAY | rtaudio Summary
RtAudio is a set of C++ classes that provides a common API (Application Programming Interface) for realtime audio input/output across Linux (native ALSA, JACK, PulseAudio and OSS), Macintosh OS X and Windows (DirectSound, ASIO and WASAPI) operating systems. RtAudio significantly simplifies the process of interacting with computer audio hardware. It was designed with the following objectives:. RtAudio incorporates the concept of audio streams, which represent audio output (playback) and/or input (recording). Available audio devices and their capabilities can be enumerated and then specified when opening a stream. Where applicable, multiple API support can be compiled and a particular API specified when creating an RtAudio instance. See the \ref apinotes section for information specific to each of the supported audio APIs.

I'm trying to use RtAudio in Linux. To start, I've compiled it with jack enabled:...

For anyone else who might be dealing with the same problem, here is how I fixed it:
I have two similar projects on the same machine. Their difference is that one is using GUI (Qt and Qwt) and the other is not. As the result, the one that has Qt is using qmake to compile and the other one cmake.
The project itself is about signal processing and working with audio. I decided to use RtAudio for capturing audio signal. I can compile and run the example code fine when I'm compiling with cmake but when I try to compile the other project using qmake, it fails.
The problem is
jack (audio library) which is not found when compiling using qmake. But first, let's start with the project that works. Here's what I have in my

To let qmake know where to find the lib please add
An audio library I'm using takes a callback function as an argument, which writes audio into a buffer.
I'm writing a class called
Instrument, in which I have a method
oscillator() which writes a sine wave to the buffer:

RtAudio::openStream() takes a user-defined parameter as input to the callback, per the documentation:
I’m using C++ on visual studio 2019 and having issues trying to link my project to PortAudio. When I use the RtAudio header file in a project, I get the error message "MidiInDummy: This class provides no functionality." Most solutions I can find online say to add
__WINDOWS_MM__ to the pre-processor definitions and link to winmm.lib (as instructed on https://www.music.mcgill.ca/~gary/rtmidi/) However, having done this, I am still getting the same problem.

I get the error message "MidiInDummy: This class provides no functionality."
This warns that no valid MIDI API was defined. The warning is issued from the constructor of the
MidiInDummy class in
rtMidi.cpp, which is just a placeholder without functional implementation.
__WIN_MM__to the pre-processor definitions
That is the wrong
#define for the Windows build, which explains the
MidiInDummy warning. The correct definition, listed on the reference page under Compiling is:
I'm trying to make an audio software (a DAW) using Electron to create the window and c++ to play audio / generate audio / apply audio effects.
I have been searching for a simple, powerful, and cross-platform library to play and process audio, and I've found
The Synthesis Toolkit and I'm really happy with it.
Here is the code (it's from the STK demo programs):...

Finnaly ! I've found by myself !
The answer is really dumb: in my
binding.gyp file, I just had to replace
I just had to change from a relative path to an absolute one...
And it took me a day to figure it out...
And I hate myself =)
