ProVideo PV-957 WDM Audio capture is a sound card produced by ProVideo Co. Ltd. Audio capture refers to the process of obtaining audio stream live from the source and changing into a file format that a computer can understand. The format of the audio file comprises several chunks. The header chunk is responsible for the description of this format as well as the quantity of samples. The two common formats of the file are AIFF, an acronym for Audio Interchange File Format and WAVE which is also an acronym for Waveform Audio. Thus the user is able to record sound such as music as well as voice from an audio device. With video capture, it is possible to record the audio as it is playing live or to copy the audio from a CD in which it has been pre- recorded.
Unless you update your drivers regularly you may face hardware performance issues.
To check your drivers you should manually verify every device on your system for driver updates
When buying a video card, there are three important things which a user should look at; the input types, the format that will be generated and the question of whether the generated content will come from one or more servers. When it comes to the inputs, it is important for the user to settle for those of high quality. The user should consider a camera which has 3-CCD capture chipset then utilize S-video in the connection of camera to input of the media card to be used for streaming. It is also advisable not to use the on-camera microphone in the process of audio capture as it will add some noise which the audio codec may find hard to translate. It is better to use an external microphone or a wireless microphone. The bit rates as well as content should also be determined. The required input ratio for multiple codecs as well as bit rates was 1:1. The final step is to determine the delivery of the captured audio and this can be done directly from capturing device or through other servers.
