This gives a simple reference * application for implementing a USB Audio Input device using the * basic USB Audio drivers in all modern OSes (i.e. no special drivers * required). * * On start-up the system will automatically enumerate and function * as a USB microphone. Incoming audio from the ADC channel 1 will * be sampled and sent to the host computer. * * To use, connect a microphone to the ADC channel 1. * * Under Windows, if a driver request dialogue pops up, select the option * to automatically install the appropriate drivers. * * \section SSec_Options Project Options * * The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value. * * <table> * <tr> * <td><b>Define Name:</b></td> * <td><b>Location:</b></td> * <td><b>Description:</b></td> * </tr> * <tr> * <td>MICROPHONE_BIASED_TO_HALF_RAIL</td> * <td>Makefile CDEFS</td> * <td>When defined, this alters the demo so that the half VCC bias of the microphone input is subtracted.</td> * </tr> * <tr> * <td>AUDIO_SAMPLE_FREQUENCY</td> * <td>Descriptors.h</td> * <td>Gives the audio sample rate per channel for the audio stream, in Hz.</td> * </tr> * </table> */Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
