A set of C++ classes that provide a common API for realtime audio input/output across Linux (native ALSA, JACK, PulseAudio and OSS), Macintosh OS X (CoreAudio and JACK), and Windows (DirectSound, ASIO, and WASAPI) operating systems. - thestk/rtaudio Attached to this post is a sample WASAPI exclusive-mode event-driven playback app, including amd64 and x86 binaries, source, and a modification of the ac3.wav Dolby Digital test tone to include a "fact" chunk. If i understood the API right the releaseBuffer call should tell the buffer which frames have already been read. I use the numAvailableFrames as Argument because i copy all the frames from the input buffer. Does anyone have experience with the WASAPI ? Sample - WASAPI loopback capture (record what you hear) I'd love to see a .NET port of this, too bad my C++ skills are too bad to wrap my head around this. Log in to Reply. Dan says: WASAPI is a C++-only API; it cannot be consumed directly from the .NET framework. Asio C++ Library Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach. Latest Stable Release A thorough tutorial in the use of NAudio, Audio Programming with NAudio. By Mark Heath. A thorough tutorial in the use of NAudio, an open source audio library for .NET. We'll then move on to look at how you can record using WASAPI. And in addition to regular recording, where you're All tutorials I saw on the internet about using the real tone cable with guitar rig teaches how to use it with Asio. I'd like to use wasapi because the latency is lower and I will be able to hear sounds from other programs, such as watching a youtube guitar tutorial or playing along my mp3s. Home Information Classes Download Usage Mail List Requirements Links FAQ Tutorial. Usage Documentation ASIO or WASAPI audio drivers. For DirectSound support Most STK classes are operating system independent and can be compiled using any current C++ compiler. STK assumes big The fiddly WASAPI stuff is encapsulated in C++ AudioOutput class with a very simple interface. Basically you create the AudioOutput, initialize it with a static callback function and an object pointer. 6 Responses to Real-Time Audio Generation Using WASAPI on Windows 8.1. Viktor To use PyAudio, first instantiate PyAudio using pyaudio.PyAudio() (1), which sets up the portaudio system. To record or play audio, open a stream on the desired device with the desired audio parameters using pyaudio.PyAudio.open() (2). This sets up a pyaudio.Stream to play or record audio. The ideas in this post apply equally to real-time audio programming on Windows, Mac OS X, iOS, and Linux using any number of APIs including JACK, ASIO, ALSA, CoreAudio AUHAL, RemoteIO, WASAPI, or portable APIs such as SDL, PortAudio and RTAudio.
