History of the Sound Card :: essays research papers
History of the Sound Card: How it Came About The very first sound card every manufactured was a Sound Blaster card. Far West was the manufacturer of the first Sound Blaster sound card. LetÃ¢â¬â¢s step back a little in time to take a look back at when sound cards havenÃ¢â¬â¢t even yet existed. Ã¢â¬Å"Computers were never designed to handle sound.Ã¢â¬ Before sound cards were invented, the only sounds you would hear from a computer would be the beeps that would tell you if something was wrong with the computer. ThatÃ¢â¬â¢s all! No sounds would accompany any games, you couldnÃ¢â¬â¢t play music at all, nothing! Computer programmers wanted to use the beeps for games they created, and so they would program the beeps into their games. However, it would be Ã¢â¬Å"awful music as an accompaniment to games like Space InvadersÃ¢â¬ . Far West came up with the solution, thus the invention of the first Sound Blaster sound card. It still wasnÃ¢â¬â¢t good quality music, but it was a big step up from just the beeps. Ã¢â¬Å"It could record real audio and play it back, something of a quantum leap. It also had a MIDI interface, still common on sound cards today, which could control synthesizers, samplers and other electronic music equipmentÃ¢â¬ . The first sound card was of 8 bit 11 kHz audio quality, similar to an AM radio. There are two parts to the Ã¢â¬Å"complicated piece of electronicsÃ¢â¬ , the sound card. ADC and DAC were they. ADC is the analog-to-digital converter and DAC being the opposite (digital-to-analog converter). ADC took an analog signal from a device and converts it to digital signals for the computer to use, as DAC did the exact opposite, taking a digital signal and converting it to analog. However, in the future, there will be no use of ADC and DAC since Ã¢â¬Å"both speakers and microphones will be able to directly record and playback digital signals directlyÃ¢â¬ . An example of ADC would be a sound through the microphone being recorded into the computer. A CD player is an example of a device that uses DAC. Ã Ã Ã Ã Ã Digital audio has its advantages. One would be that Ã¢â¬Å"no matter how many times it is copied it remains identicalÃ¢â¬ . It does not degrade analogue sources. An example of an analogue source is vinyl. A leap up to 16 bit 44.1 kHz was a major development. This is the quality of a CD. This became a problem for the ISA bus.
