kandi X-RAY | rtaudio Summary

rtaudio is a C++ library. rtaudio has no bugs, it has no vulnerabilities and it has medium support. However rtaudio has a Non-SPDX License. You can download it from GitHub.

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.

            Making RtAudio use jack for audio capture
            Asked 2022-Feb-17 at 22:27

            Linking with jack using qmake
            Asked 2022-Feb-15 at 03:26

            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 CMakeLists.txt file:

            How can I pass a non-static class method as a callback function in C++?
            Asked 2021-Feb-17 at 02:16

            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:

            Answered 2021-Feb-17 at 02:16

            RtAudio::openStream() takes a user-defined parameter as input to the callback, per the documentation:

            How to compile RtMidi API properly on Windows
            Asked 2020-Dec-25 at 19:19

            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.

            add __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 just had to change from a relative path to an absolute one...
