This is an obsolete module and is only available for backward compatibility.
Please check the new Audio Recording Module.
The Audio Input Output Module (AIOM) allows users to record from single or multiple audio track sources to a wav / bwav file format, in parallel to the video recording to a StreamPix sequence file. Great care has been taken so that the module maintains accurate synchronization between audio and video, provided there is sufficient disk bandwidth available to allow recording of both media. To access the audio source devices (sound card), as well for playback, the module can either use a MME/DirectX or an ASIO driver.
Which driver interface should be selected? The MME/DirectX driver interface is always available, for all Windows compatible audio devices. The DX driver is somewhat limited, and can support only up to 2 audio channels. The ASIO driver typically exists with all professional related audio devices but ASIO4ALL is a hardware independent, low latency ASIO driver for WDM audio devices (http://www.asio4all.com).
The ASIO device driver, when available, is always preferable. It allows for better control of all the device properties, and can provide better quality data. Among the module features we can mention:
