What value: decibels? Sample rate? Frequency? Pan?

Tell us what you're trying to do and we can be more helpful.

But first, a hint: DO NOT use mp3 audio in AE. Convert it to wav or aiff. Audio files are just too small in file size to take the risk of compressed audio behaving badly in AE... and it occasionally does.

1) i need to trim right audio file and i gonna write some code for the trimming

2) i need to tie some audio waves to some visual effects.
it's like "audio spectrim" and "audio wave forms".
i don't need using for example: audio spectrum + polar coordinaties + glow and etc. it's powerful effects.
but i need to make different effects, for example: talking cat - cats lips are changing on current audio stream.

it would be nice to get audio parameters at some time:
decibels, sample rate, frequency, pan and etc.

How about Convert Audio To Keyframes? Works pretty well for animating by volume. If you want to limit the frequency at which you animate the volume, look at Trapcode Soundkeys.

You see, some of this stuff has already been thought of.

And I'm scratching my head over the usefulness of trimming up an audio layer with a script. It seems like WAY more trouble than it's worth, not to mention a lot more time-consuming than scrubbing and keystroke combination.
