![]() Higher bit-depth samples offer the potential for a higher signal-to-noise ratio. In addition, ASIO supports 24-bit samples, unlike Windows NT 5.x MME and DirectSound which truncate 24-bit samples to the upper 16 bits, whereas Windows NT 6.x mixer provides 32-bit floating point output. Audio Stream Input/Output (ASIO) is a computer sound card driver protocol for digital audio specified by Steinberg, providing a low-latency and high fidelity interface between a software application and a computers sound card. Unlike KMixer, an unmixed ASIO output is "bit identical" or "bit perfect" that is, the bits sent to or received from the audio interface are identical to those of the original source, thus potentially providing higher audio fidelity. Its main strength lies in its method of bypassing the inherently high latency and poor-quality mixing and sample rate conversion of Windows NT 5.x audio mixing kernels (KMixer), allowing direct, high speed communication with audio hardware. In this way ASIO offers a relatively simple way of accessing multiple audio inputs and outputs independently. ![]() Select Search automatically for updated driver software. Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update. 64-Bit, Mac OS 10.6.7 32-Bit Improved driver performance receiving audio input. Update the device driver In the search box on the taskbar, enter device manager, then select Device Manager. Each layer that is bypassed means a reduction in latency (the delay between an application sending audio information and it being reproduced by the sound card, or input signals from the sound card being available to the application). This package installs the software (Audio driver) to enable the following device. This is the final driver release for the Fast Track USB. Whereas Microsoft’s DirectSound is commonly used as an intermediary signal path for non-professional users, ASIO allows musicians and sound engineers to access external hardware directly.ĪSIO bypasses the normal audio path from a user application through layers of intermediary Windows operating system software so that an application connects directly to the sound card hardware. ![]() Audio Stream Input/Output ( ASIO) is a computer sound card driver protocol for digital audio specified by Steinberg, providing a low-latency and high fidelity interface between a software application and a computer's sound card.
