basically a sound card does turn an analogue signal into digital is true. People who only use software won't need it. |

Hey, someone comes out of the bog with something smart. And its my contention that most people use software pretty much exclusively. |
cronodevir and orTofønChiLd, there are huge holes in your knowledge. before you start arguing a point, it usually helps if you actually know what you are talking about. otherwise, you just come off looking like retards (like what has happened in every thread you post in).
the main reason people buy soundcards is for the better digital to audio converters. your onboard soundcard would have piss poor DAC, in the range of ~90db SNR, with very high jitter. my echo audiofire has 113db SNR, and very low jitter. every 3db is DOUBLE the percieved loudness. hence, my output is over 700% better, in terms of loudness in SNR. latency has NOTHING to do with DAC. latency is a software buffer. DAC is a digital circuit in hardware. at any latency, my soundcard will STILL be more than 700% better, in terms of SNR loudness.
why is this important? YOU NEED ACCURATE OUTPUT TO BE ABLE TO HEAR ALL THE DETAILS IN YOUR SONG. your onboard soundcard does not give you accurate output, because it is a piece of shit. you need accurate output REGARDLESS of whether you are using hardware OR SOFTWARE.
another reason why your onboard soundcard sucks is because it has shit quality opamps, which amplify the signal. professional soundcards have high quality opamps and only ever output at line level. likewise, since your soundcard is part of your motherboard, the DAC is not isolated from interference from other things inside your computer. your CPU fan, hard drives and even just crosstalk from circuit tracks that are too close, will cause interference. hence, onboard soundcards also have a VERY high amount of distortion, due to interference. even PCI soundcards distance the circuits far away enough to solve this problem. the best solution, however, is obviously to have an external card.
latency has NO effect on sound quality. if your buffer is too low, however, you will get gaps in the audio stream. gaps != lower quality. latency is just a buffer. the buffer exists because your computer cannot output a constant stream, so the computer needs to "read ahead" a certain amount of time, to avoid problems when the CPU spikes and can't provide a constant audio stream. when you run out of buffer, because your CPU can't handle the load, then you get clipping because the audio stream gets gaps in it. having a larger buffer makes absolutely NO difference on sound quality.
