A sound card is a computer component responsible for generating and recording audio.
It enables users to connect analog speakers, headphones and microphones to their computer.
Most modern computers have a built-in sound card in the motherboard..
Sound cards use a digital-to-analog converter (DAC), which converts recorded or generated digital signal data into an analog format.
The output signal is connected to an amplifier, headphones, or external device using standard interconnects, such as a TRS phone connector..
A sound card allows a computer to create and record real, high-quality sound.

Before the invention of the sound card, a PC could make one sound - a beep.
Although the computer could change the beep's frequency and duration, it couldn't change the volume or create other sounds..

The main function of a sound card is to convert audio information between analog sound and digital data.
Sound cards can be built into a motherboard or added later as a dedicated audio device.
However, dedicated sound cards typically offer higher audio quality because they are made with better components..
Some clever people recognized that the sound cards were, in essence, data acquisition systems themselves.
They could take analog data and convert them to computer-readable files or take computer readable files and convert them to analog outputs.
Of course, you can multiply your measuring power by running the output of the distortion analyzer into the sound card measurement system, allowing it to be monitored in the time domain (i.e., virtual oscilloscope) or the frequency domain (i.e., spectrum analyzer).
Use MATLAB to acquire and analyze data from Windows sound cards.
Ready to install.
MATLAB ® and Data Acquisition Toolbox™ support Windows ® compatible sound cards that use the DirectSound driver.
You can purchase entry-level sound cards for $20 or less, or you can choose feature-laden professional models for hundreds of dollars.
At its introduction in mid-1995, the Creative Labs AWE-32 listed for $399 and sold at a street price of approximately $169, or about what a higher-performance version from the same vendor costs today.
