@balavignesh002 @Passive_audio_enthusiast we have many (mis)conceptions about digital media, that I belive purely came from analog world. Just to give you some example that causes variability in analog recording -
1. Recording deck
2. Recorder settings
3. Quality/brand of recording tape/cassette
All these three factors affects recording quality in analog cassette. Moreover, copying a cassette degrades its sounds. All these are proven facts. Surprisingly, anyone can find these concepts in digital worlds too. Just like the following points to summerise -
1. CD copy affects sound quality
2. Burner have an effect on copied material
3. Burning software have an effect on copy quality
4. Different brand of disk have impact on copy quality
Now, all these point are summerised on the basis on what I "think". Thinking anything doesnt prove a matter. Digital copying works in a differrent way than analog copy method. And the copied out files can easily be checked by various tools for errors coupled with human perception tools. Since our auditory perception is faulty, and majority time our brain "fool" us, it is good to check the copied files for any copy error using different available tools if someone is really inclined to. There is another point I need to mention, I came across many statements in various places about the apparent difference of output of a copied audio CD, but never saw a discussion about the quality of a copied data CD. If quality suffers in audio CD, it should suffers in data CD too. But do it happens? I can give you some classic example in this regard if you guys are really inclined in this.
Regarding the four points that I have summerised above about my "thinking", I can say that I am already conducting a blindfold test regarding the point 1, i.e. SQ change during CD copy here in hfv. Exciting result of the test is expected. I have plan to conduct similar blindfold test regarding other points too.
@balavignesh002 you can visit my thread regarding the blindfold test if you are interested in the following link.
Hello All, There is a common saying that the sound of the Original Audio CD degrades/changes when it is copied, just like the degradation of sound during Audio Cassette copy. Here I am presenting a Blindfold Test through public polling regarding this issue to address the phenomenon. The test...
