does anybody here know some good audio library that has much to offer
at tweaking source input level of recording a sound?
...and what would be the best mic used for recording largest sound spectrum possible with it?
...and if there is a mic that captures only sound that one is interested in - some kind of filter,
or it's the same if is 'filtered out' later by software? - probably not.
to test - laptop mic is enough

libraries:
-openAL: has AL_GAIN(srcLevel?) to tweak and some others, but i can't determine when playback is finished
 because AL_SOURCE_STATE seems to be always in AL_PLAYING state, and when i set AL_LOOPING to true,looping
 is there for some time, then it becomes 'scratchy' and stops playing - maybe there is some hokus-pokus
 to write or something so that it works properly though
-portAudio: maybe - didn't test the code yet - but seem it has less options to tweak(orEqual)
-SFML: easy sound rec integration - but has less options to tweak
