Sound AC97

It revealed the soundcard Genius SoundMaker 5.1 and revealed old lady - Creative Sound Blaster 5.1 live!

Workstation was replaced. On the motherboard is established the sound codec AC97 Azalia. It listened to - and it arrived into the horror. Sounding reminded me of almost already forgotten grand-dad AC97 of codecs - device covox.

When this was? It does seem, it was 1993? In the friend was the modem! At station BBS of I download small file with description DAC for LPT Covox. Everything proved to be simply - resistance DSP. Usual chain R-2R diagram. For the assembling to me it was necessary to purchase boot-tree LPT and sixteen resistors. It soldered and placed diagram in the case from the toothbrush. To connect the made article to the computer greatly feared. Multicatd they cost very and very dearly. It connected. Smoke and the smell of burned down multicard it did not feel. Run FastTracker and opened file “at.mod”. Here is it - MIRACLE created by its own hands. It is possible to say that precisely from this day began my “unhealthy” enthusiasm by music. But further they were Space Quest and King’s Quest, Wolfenstein 3D and tracking music.

But I will return to codec AC97 Azalia. Already it described about grand-dad AC97. Grandson inherited genes and to qualitatively reproduce sound it is not categorically capable. As a whole codec AC97 this is good. Sounding it manages. Windows, ICQ and periodically “You have new mail message”.

AC97 codec - microcircuit. The microcircuit, whose output signal, is not capable to maintain the load of my headphones. Usual linear output for the connection of “active acoustics”. Usual headphones do not have the built-in amplifier and possess resistance in the range from 0.032 to 0.050 kilohms with the connection of headphones their low resistance it causes the short circuit of the “linear output” of codec. Don’t fear - codec from this not burning down, but here the quality of signal seriously deteriorates. Sound will be very and very quiet, and from its spectrum it is disappeared all low-frequency constituting.

The whole day on the work without the dear headphones and without the sound. In the evening house it began searches in the distant cabinet. It revealed the soundcard Genius SoundMaker 5.1 and revealed old lady - Creative Sound Blaster 5.1 live! It purchased I it in the fall of 1998. In this year to the soundcard OF EIGHT years. Period on the computer measures is enormous. Established SoundBlaster into the computer. Here Is IT! Present valuable map is prepared on chip EMU10K1. In the headphones customary completeness and low-frequency sound immediately appeared. Yesterday l0ner came to me in guests to the cup of coffee. It can confirm that the headphones play excellently! ;-)

Certainly, in AC97 codecs there are focusings from the digital signals of those going along the tires of motherboard. There are no digital circuits of the filtering capacitors. Yes you will look themselves - chip is located, that to maximally simplify the separation of motherboard, but not to improve the quality of sounding. To take the second card which I brought to work Genius SoundMaker 5.1. On the quality was obtained the sound from AC97 codec. Components on the map very cheap, processor weak, and the device of amplifier - are lower than any criticism. It rejected map into the debris bucket, where for it place itself.

So that to you personal request - do not be satisfied by the possibilities of the built-in sound. Not limit their own perception of music, films and games. However, the built-in codec AC’97 for this is unfit. Better you will accumulate money on the decent sound card.

p.s. For those, who remembers the grandfather covox - here it is possible to load that AT.MOD.

p.p.s. But where now your covox?

Абхазия
Реферат подготовила Удинцова С.Н. Особенности природы Абхазия - типичная горная республика. Горы занимают 64% территории. Это главный Кавказский (или Водораздельный), Гагрский, Бзыбский, Абхазский, Кодорский хребты и их отроги. Высшая точка Абхазии - гора Домбай-Ульген на границе с Россией (4046 м). Горы прорезаны долинами коротких, но полноводных порожистых рек; это Псоу, Бзыбь, Гумиста, Келасури, Кодори, Ингури.
