Sound card Wikipedia. A sound card also known as an audio card is an internal expansion card that provides input and output of audio signals to and from a computer under control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment games and video projection. Sound functionality can also be integrated onto the motherboard, using components similar to those found on plug in cards. The integrated sound system is often still referred to as a sound card. Sound processing hardware is also present on modern video cards with HDMI to output sound along with the video using that connector previously they used a SPDIF connection to the motherboard or sound card.

The output signal is connected to an amplifier, headphones, or external device using standard interconnects, such as a TRS phone connector or an RCA connector. If the number and size of connectors is too large for the space on the backplate, the connectors will be off board, typically using a breakout box, an auxiliary backplate, or a panel mounted at the front.

More advanced cards usually include more than one sound chip to support higher data rates and multiple simultaneous functionality, for example digital production of synthesized sounds, usually for real time generation of music and sound effects using minimal data and CPU time. Most sound cards have a line in connector for an input signal from a cassette tape or other sound source that has higher voltage levels than a microphone. The sound card digitizes this signal. The DMAC transfers the samples to the main memory, from where a recording software may write it to the hard disk for storage, editing, or further processing. Another common external connector is the microphone connector, for signals from a microphone or other low level input device. Input through a microphone jack can be used, for example, by speech recognition or voice over IP applications. Sound channels and polyphonyeditAn important sound card characteristic is polyphony, which refers to its ability to process and output multiple independent voices or sounds simultaneously. These distinct channels are seen as the number of audio outputs, which may correspond to a speaker configuration such as 2. Sometimes, the terms voice and channel are used interchangeably to indicate the degree of polyphony, not the output speaker configuration. For example, many older sound chips could accommodate three voices, but only one audio channel i. Later cards, such as the Ad.

For some years, most PC sound cards have had multiple FM synthesis voices typically 9 or 1. MIDI music. The full capabilities of advanced cards are often not fully used only one mono or two stereo voices and channels are usually dedicated to playback of digital sound samples, and playing back more than one digital sound sample usually requires a software downmix at a fixed sampling rate. Modern low cost integrated soundcards i. AC9. 7 standard and even some lower cost expansion sound cards still work this way. These devices may provide more than two sound output channels typically 5. MIDI reproduction these tasks are performed entirely in software. This is similar to the way inexpensive softmodems perform modem tasks in software rather than in hardware. Also, in the early days of wavetable sample based synthesis, some sound card manufacturers advertised polyphony solely on the MIDI capabilities alone. In this case, the cards output channel is irrelevant typically, the card is only capable of two channels of digital sound. Instead, the polyphony measurement solely applies to the number of MIDI instruments the sound card is capable of producing at one given time.

Today, a sound card providing actual hardware polyphony, regardless of the number of output channels, is typically referred to as a hardware audio accelerator, although actual voice polyphony is not the sole or even a necessary prerequisite, with other aspects such as hardware acceleration of 3. D sound, positional audio and real time DSP effects being more important. Since digital sound playback has become available and single and provided better performance than synthesis, modern soundcards with hardware polyphony do not actually use DACs with as many channels as voices instead, they perform voice mixing and effects processing in hardware, eventually performing digital filtering and conversions to and from the frequency domain for applying certain effects, inside a dedicated DSP. The final playback stage is performed by an external in reference to the DSP chips DAC with significantly fewer channels than voices e.
