Have a cooperative application, it's not too bad you can write aĭirectShow source filter that talks to the actual hardware device. What you ask is a surprisingly difficult and complicated task. Please point me to the right direction where I can get a quick start (sample code, articles, etc). > I'm an experienced Windows/C++ programmer but completely new to device driver programming. Hangs out there, and they are very responsive to questions. You might ask your question on the wdmaudio mailing list, Since you could write your filter as an LFX APO entirely in user mode. It may actually be easier to start with Vista,
Target platforms are XP, 2003 and later.īe aware that Vista uses an entirely different design and philosophy for The application should present itself as a device so that if a user chooses to use it instead of standard audio input hardware, it starts doing its job. After every reboot, it will work again for an additional 60 minutes.> I am planning to write an application which intercepts data from microphone, processes it, then hands over to upper level clients. The trial version of LoopBeAudio works for 60 minutes after its first use. Free Evaluation Copyĭownload our free evaluation copy here. It keeps LoopBeAudio's playback and record format in sync, displays details like format, monitor and default device and gives you fast access to the Sound Control Panel. LoopBeAudio's driver comes with a small system tray application. While using LoopBeAudio you can forward the audio data to your "real" audio output, without the need for matching formats A little Status Application in your System Tray. LoopBeAudio lets you configure an audio device with more than 8 channels, but Windows will not provide the speaker positions here, therefore LoopBeAudio will behave like a multichannel Line device Independent Monitoring LoopBeAudio's "Internal Playback" simulates virtual speakers with all possible surround configurations of Windows.Ĭonfigure up to 24 channels with Virtual Line devices Test every Surround Setup with Virtual SpeakersĬonfigure LoopBeAudio with the Windows Sound Control Panel like every other audio device. Programs do not need to link with special libraries, so LoopBeAudio works with every audio-capable Windows application. LoopBeAudio is a native Windows™ WDM kernel mode driver, so expect the lowest possible latency. Build a virtual 7.1 surround device, even though you don't have the built-in hardware. Configure up to 24 audio channels, a sample rate from 8000 Hz to 384000 Hz with a bit depth from 8 bit to 32 bit. The technical limits are only restricted through the Operating System. LoopBeAudio is a virtual audio device to transfer audio between computer programs, digitally, without any quality loss. LoopBeAudio A Virtual Audio Cable - An Audio Loopback Driver
