making "hard to encode" samples?, any musician making it? Options

[iLLBeaTz]

I'm interested in audio compression
and thought why search for hard to encode
audio samples
why don't you just make one yourself
so I came up with one sample
which I made using my cheap
rhythmtrak-323 from zoom which I bought
like a monthago
its based on a drum loop plus
lots of percussion just jamming together
so anybody wants to try it
please do so
I dont have good ears nor good headphones
so I can't test how difficult encoding this sample
and now my actual question
are there any musicians here
specialising in hard to encode samples?
and finally just by adding many instrument
overall bitrate goes up giving you
hard to encode stuff am I right?
or are there specific instrument
which is hard to encode?
I really need some help I wanna
contribute to this wonderful HA society
you know
any help,suggestion,advice,tips
everything is welcome

i'll up the sample in a minute

thanx

Adding more instruments doesn't neccessarily make the bitrate go up. With more overall sound, there are also many more places to hide the noise introduced during encoding. A general statement like this can not be made.

Picture this: you're looking at a wide open plain with just a single tree on it. That tree represents an instrument or a specific sound and the plain with everything that's on it is the signal you want to encode. Now along comes your encoder and chops up the tree. Since that tree stands out so much, you will instantly notice if it changes, so the encoder has to be especially careful. On the other hand, you might also be looking at a whole forest. Again your encoder comes along and it has to chop up the individual trees real bad, because of limited storage space. But from your viewpoint you still see a whole forest even though the trees have gotten quite a beating. It could also happen that large patches of the forest have been completely removed and that would surely catch your eye. The thing is, it is hard to tell in advance.

or are there specific instrument
which is hard to encode?

The harpsichord has often caused trouble. It combines transient with highly tonal signals. Even in that case it will depend a lot on how it was recorded and post processed.

Also keep in mind that the codecs discussed here were designed to compress audio content and not the signal of your remote temperature meter.

really? thats cool
i'm gonna get some harpsichord
sample and play with it
