00:00:00,240 --> 00:00:05,760
It wasn't too long ago that if you wanted good or even passable sound from your computer,

2
00:00:05,760 --> 00:00:08,820
you'd need a dedicated sound card.

3
00:00:08,820 --> 00:00:14,160
But nowadays, even though you can still buy them, most PC enthusiasts recommend you skip the sound card

4
00:00:14,160 --> 00:00:18,280
entirely and just instead use the audio that's integrated into your motherboard.

5
00:00:18,280 --> 00:00:21,520
So how did this happen? To understand, we need to take a look back

6
00:00:21,520 --> 00:00:25,160
at why dedicated sound cards even existed in the first place.

7
00:00:25,160 --> 00:00:29,720
You know that little PC speaker that comes with some other boards that beeps at you

8
00:00:29,920 --> 00:00:33,640
to let you know that your computer booted okay or has some kind of issue?

9
00:00:33,640 --> 00:00:36,680
Well, way back during the 1980s,

10
00:00:36,680 --> 00:00:40,240
when the original IBM PC and compatibles ruled the day,

11
00:00:40,240 --> 00:00:45,480
a larger version of that little speaker was the only source of sound for many users.

12
00:00:45,480 --> 00:00:50,120
This means that you would be limited to just beeps and boops, though there were some tricks

13
00:00:50,120 --> 00:00:54,840
that programmers used to get the PC speaker to make other sounds, such as this box piece

14
00:00:54,840 --> 00:00:57,880
that was used as the intro to a 1982 classic

15
00:00:57,880 --> 00:01:02,080
called Paratrooper. As you can tell, the speaker didn't exactly sound

16
00:01:02,080 --> 00:01:05,320
all that great and early PC CPUs also had

17
00:01:05,320 --> 00:01:10,320
to more or less drop everything else they were doing while that speaker was trying to chirp at you.

18
00:01:10,320 --> 00:01:16,560
So obviously a better solution was needed. So the idea was to offload audio processing

19
00:01:16,560 --> 00:01:22,240
to a separate sound card so that the system wouldn't have to depend solely on the main CPU.

20
00:01:22,240 --> 00:01:27,400
And as the years went by, sound cards supported more and more features and better and better audio quality,

21
00:01:27,400 --> 00:01:32,520
partly due to their role as hardware accelerators, meaning that the extra hardware on the sound card

22
00:01:32,520 --> 00:01:37,400
could do the heavy lifting of processing all that audio instead of leaving it all to the CPU.

23
00:01:37,400 --> 00:01:42,600
Similar actually to the difference between having a discrete graphics card and onboard graphics,

24
00:01:42,600 --> 00:01:46,480
except without a dedicated area on the CPU die for audio.

25
00:01:46,480 --> 00:01:51,840
And while it is true that integrated audio for motherboards became more prevalent in the late 1990s

26
00:01:51,840 --> 00:01:57,200
thanks to Intel's AC97 audio codec that got incorporated into onboard chips,

27
00:01:57,200 --> 00:02:02,440
sound cards were still more powerful solutions that delivered noticeably better quality.

28
00:02:02,440 --> 00:02:07,340
So folks that care about audio didn't have much reason to ditch sound cards just yet.

29
00:02:07,340 --> 00:02:12,280
That said, sound cards weren't perfect. Because hardware acceleration for audio

30
00:02:12,280 --> 00:02:15,400
was implemented differently by different manufacturers,

31
00:02:15,400 --> 00:02:18,960
you needed a specific driver for your car to work properly.

32
00:02:18,960 --> 00:02:23,840
Kind of like how you need a specific AMD or NVIDIA driver these days for your graphics card

33
00:02:23,840 --> 00:02:28,080
to function. These drivers were often notoriously poorly written

34
00:02:28,080 --> 00:02:31,080
and unstable. So starting in Windows Vista,

35
00:02:31,080 --> 00:02:34,400
Microsoft tried to standardize how audio was handled,

36
00:02:34,400 --> 00:02:39,320
which also enabled features like per application volume control from the operating system itself.

37
00:02:39,320 --> 00:02:43,040
And did it by forcing the system to handle audio in software

38
00:02:43,040 --> 00:02:48,080
instead of through a hardware accelerated card. This meant that the CPU was suddenly handling

39
00:02:48,080 --> 00:02:51,880
a lot more audio processing. And in games and other applications

40
00:02:51,880 --> 00:02:56,040
that were built around hardware acceleration in the form of a sound card,

41
00:02:56,040 --> 00:03:01,360
many users experienced buggy audio and performance issues early on.

42
00:03:01,360 --> 00:03:06,160
However, the good news is that by this point, CPUs were already powerful enough

43
00:03:06,160 --> 00:03:09,760
to handle audio processing without a big performance hit,

44
00:03:09,760 --> 00:03:12,860
a far cry from the early PCs we mentioned previously.

45
00:03:12,860 --> 00:03:16,440
So as applications started to catch up and support software based standards

46
00:03:16,440 --> 00:03:21,000
like Microsoft's universal audio architecture, it became the case that all you needed

47
00:03:21,000 --> 00:03:25,880
for good quality sound was a modern CPU and an audio device that supported UAA,

48
00:03:25,880 --> 00:03:31,200
such as those real tech HD audio chips that are now ubiquitous on all motherboards.

49
00:03:31,200 --> 00:03:34,720
These chips are much simpler than full blown sound cards.

50
00:03:34,720 --> 00:03:37,720
As much of the work that would be done by a sound card's processor

51
00:03:37,720 --> 00:03:43,160
can be handled by the main CPU of the system, leaving the real tech chip to handle simpler tasks

52
00:03:43,160 --> 00:03:48,640
like digital to analog conversion. And as quality has improved on the real tech chips themselves

53
00:03:48,640 --> 00:03:52,320
and motherboard manufacturers have taken care in designing their audio circuits

54
00:03:52,320 --> 00:03:56,300
so that they won't be as affected by electrical interference from the rest of the system,

55
00:03:56,300 --> 00:04:00,600
today we're at the point where onboard audio is actually quite good.

56
00:04:00,600 --> 00:04:04,560
Separate sound cards, while they can still give slightly better audio quality,

57
00:04:04,560 --> 00:04:09,280
are often only recommended for enthusiasts who need the extra processing muscle

58
00:04:09,280 --> 00:04:13,800
for a niche applications or for specific ports. But even users who need a bit more power

59
00:04:13,800 --> 00:04:19,360
for their high impedance headphones are often advised to get an external DAC slash amp

60
00:04:19,360 --> 00:04:23,400
instead of a sound card. As external solutions are often isolated completely

61
00:04:23,400 --> 00:04:27,020
from the electrically noisy environment inside a PC.

62
00:04:27,020 --> 00:04:30,720
But if you do end up needing a sound card for some reason,

63
00:04:30,720 --> 00:04:36,480
don't think that their development has been totally neglected. I mean, after all, you can get them with RGB.
