a little test re: sound-quality
a little test re: sound-quality
.. since obviously so many of you are concerned or insecure about the sound quality of their tools I want to invite you to do a little test with me on this grey sunday. ( at least in Berlin).
Here are three soundfiles:
http://www.monolake.de/files_audio/temporary/A.wav
http://www.monolake.de/files_audio/temporary/B.wav
http://www.monolake.de/files_audio/temporary/C.wav
All three files are technically 44.1kHz Stereo, 16 bit.
before I tell you more, I would just be curious to know what you think is the difference between the files.
And, this test has nothing to do with Live, it is really just about perception of sound quality versus technical quality!

oh, sorry, upload problem.... please throw files away if you already took them and grab them again....

Re: a little test re: sound-quality
SPOILER BELOW
They're identical. Phase inversion nulls them completely.
But quality-wise it sounds great. I'm not really sure what I'm supposed to say.

Re: a little test re: sound-quality
Ok, I listened to it using my Sennheiser HD-25
and the linear HD-250. I've written down my
results - won't post them yet so nobody will
be influenced...

No, they are not identical bitwise. Please try downloading them again! And try again !Komodovaran wrote:SPOILER BELOW

Re: a little test re: sound-quality
maybe PM your findings, and I collect them and post them in say 3 days to give people enough time to try.. ?

Yep, they're different (but the same size, so that's good):
Code: Select all

I found phase inversion does cancel a lot, but not completely.Komodovaran wrote:SPOILER BELOW

Re: a little test re: sound-quality
of course not, they are not all identical.
the question is: which one sounds 'better' and why so ?

Re: a little test re: sound-quality
B & C sound identical and with a little more presence and clarity in relation to A

Re: a little test re: sound-quality
I find them to be so very identical, that the only difference is the one I'm making up in my head from the stream of thoughts that vary every second.
If you had never said they were different, I could be listening to the "same song" for all eternity. Now that I know they're different I will subconsciously come up with different listening results.
Okay, so not completely null, but still I'd call that inaudible unless you're making things up in your head.

Re: a little test re: sound-quality
Yeah, I heard that _sometimes_, but then I'd listen again and it would evaporate. I even heard it as a slightly 'deeper' low end a few times. Maybe my ears are too old, or maybe my headphones are crap. "A" seemed to sound a teeeny bit more flat most of the time.Magik_10 wrote:B & C sound identical and with a little more presence and clarity in relation to A
Never realized there was so much chorus on the vocal on that track. Haven't listened to that in a long time.
Re: a little test re: sound-quality
Yeah, the difference is there, but its _really_ subtle. Maybe it's dithering or something? There may be some hidden message in there at -120db that will make us all go mad.Komodovaran wrote:I find them to be so very identical, that the only difference is the one I'm making up in my head from the stream of thoughts that vary every second.

Re: a little test re: sound-quality
I agree the difference is subtle. The question is: which ones do you like more / which versions sound 'better', and if so, what does 'better' mean....
