USB Audio 2.0 Class Driver for Windows

Features      Supported Platforms      Demo      Prices      

Thesycon’s USB audio class driver TUSBAudio targets USB audio devices for professional and semi-professional use and highest quality audiophile HiFi systems. The driver supports devices which are compliant to the USB Audio 2.0 or USB Audio 1.0 device class specification. The driver provides an ASIO 2.2 compliant software interface and integrates with Windows as a standard WDM/DirectX compatible sound device. If the device provides MIDI features the driver exposes standard Windows MIDI ports.

To meet professional audio requirements, the audio class driver is optimized for low latency and low CPU load. Buffer depths can be adjusted by the user to optimize settings for a given computer. The driver implements a transparent (bit-perfect) playback and recording data path.

Device and Firmware Requirements

The USB Audio 2.0 Class Driver for Windows implements the USB Audio 2.0 and 1.0 device class specification and is independent of the specific silicon and firmware solution used in a given device. As long as the hardware and firmware implement the descriptors, endpoints and requests defined in the class specification the driver should work. However, there are some requirements and assumptions as listed below.

The free evaluation version of the TUSBAudio device driver includes all features but has a time-bomb restriction. After the device is connected, the evaluation driver works for an interval of 60 minutes without any limitation. After that interval has expired the driver inserts a short beep tone into all input and output audio channels every five minutes. The driver stops receiving and sending MIDI data after the interval has expired. The evaluation interval can be restarted by unplugging and re-plugging the device.
