MW Posts: 9	Posted - Tue May 13, 2003 9:29 am  Hi there, After using PC for more than 15 years in music I came to a crazy thingy. Using different different audio-applications on different machines all using W2K (no crack ****, we even bought Windows, just to mention my opinion again and again, if you are making money with music you have to pay for what you are working with, all other people should go with their attitute) and different audio interfaces MDelta, RME, Apogee. Just Installing a audioprogram and even not running, the sound is minimalistic different while playing instruments through the inputs. Installing another prog, again minimalistic different, deinstalling it, itīs like before. Itīs not remarkable. Itīs hearable only if you searching for it and we got it only through nice headphones. Whatīs the reason for it? Is it the driver-architecture ? Do the audio-apps changing driver-registry entries? Is it only with the PC/Windows ? Does anybody remarks this thingy, also ? Thanks MW

Or are you saying that sound recorded with one app sounds different to identical sound recorded with the same soundcard and a different app? I'm afraid it's not quite clear... _________________

However, if you are saying that different sound/audio cards sound marginally different, then they probably do. Essentially, they are pushing and audio signal through electronic circuitry which will have a greater or lesser degree of effect on that signal. After all, if you said "I can hear minor differences between two amplifiers" then nobody would be likely to disagree with you, would they? If, on the other hand, you are saying that the same audio interface is producing different sounds, dependent on the software it is plugged into, then I find that a lot harder to believe. Particularly as you are monitoring the input, not the output. _________________ Graeme Don't forget to join the new CEP forum at audiomastersforum

I did not touch the hardware between recordings, I simply recorded, saved the file, closed that program, open the next program, and repeated. I looked at the recordings in CE. Each one looked distinctly different than the others, when zoomed in far enough to see the wave forms at that low signal level. Also, the Statsistics results were enough different to appear not to be random. The results were repeatable. At that time I did not really know about Spectral View or Frequency Analysis; I don't believe I used anything except Edit View and Statistics to investigate. The card was one I eventually returned as being too noisy. I was mainly trying to bolster my position that the card was not good and the retailer should take it back, so I did not pursue this line after getting a new card and seeing that it was acceptable.

Each one looked distinctly different than the others -AndyH If you're recording noise floor, aren't you essentially getting whatever junk noise is flying around the computer busses at the time? That might vary depending on factors such as where things are loaded in memory. So I'm not surprised you would see differences. Repeatability is an interesting point, though. Quote: Using different different audio-applications on different machines all using W2K -MW MW, it sounds like you are changing almost everything, except the W2K and headphones. You are changing applications; machines; presumably (due to the machine change) soundcards, amplifiers; and maybe also what material gets played live or recorded. IMO it's pretty hard to start pinpointing the cause of sound differences when there are so many variables. Maybe we still just don't understand your question yet? :???: -clintfan

But this had me thinking when the thread first started: MW wrote: ...Just Installing a audioprogram and even not running, the sound is minimalistic different while playing instruments through the inputs. Installing another prog, again minimalistic different, deinstalling it, itīs like before. So. I'm wondering if this part of the question might be answered by the fact that a software installation can easily install/uninstall codecs, change associations, and of course, invoke the WaveMapper instead of addressing the audio card directly. These can make obvious changes in the way things sound. But I think we'll have to wait for clarification from MW as to exactly what was meant. Best... -Jon _________________
