I still can't understand/perceive attack

 

[matthewh133]

Attack is the amount of time it takes for a note to reach it's peak amplitude. So, I guess a practical example related to headphones is a faster attack will mean notes will be separated better and thus, won't blend in with each other which can sound muddy.

thanks, your explanation on the separation of notes made me finally understand it

I miss fatiguing, well after experiencing it with rubbish earphones, I kind of like not having it.

I've looked around for a definition of this phrase:  driver flex.  Used in conjunction with descriptions of IEM earphones.
 
Is there a commonly accepted definition?   

 

[jjmai]

I believe drive flex is the sound you hear with some dynamic IEMs when they are inserted into your ear - the diaphragm moves during that time as pressure changes, making this noise that sounds like crumpling aluminium foil.

 I've added:
- another, and hopefully more helpful, definition for Attack;
- a definition for Accurate;
- a definition for Treble.

When you do update things, please also edit the wiki entry which I created for this.

Thanks!

Subs..

how would you define "neutral" ?? and "fowarded"?

 

[peaceful1]

can some one say what roll off & cut off stands for?!
at first I thought when a graph falls suddenly it's called cut off but when it drops smoothly it's roll off but one of my friends told me when the graph drops in the high frequency it's roll off when it's about the low frequency it's cut-off 
I now the question sound stupid but it is  bothering me for a long time 
---------------------------------------
& can someone please explain what cold & worm sound actually means?!
 
 
I know these stuff are very basic but sometimes it make me feel confused

The natural sound of a headphone can have roll-off in the highs or lows, but it can't have cut-off, that's digital.
 
I believe that's what the difference is, unless someone would like to correct me.

I think these might help. Unfortunately, both concepts are beyond the intent of this glossary - to describe sound.

Forward (ness) is included on the list already. I I'll try and find a good definition for 'forward'.
