I'm a bit too much confused about the real use of 'a/the' articles.
I've recently read articles about compressors (it's a hardware or software tool for audio) and have two questions.
- They all start with 'a compressor' and then go with 'the compressor', like in this example:
A compressor includes several controls to help you control exactly how it behaves:
The level where the compressor begins working is called the threshold—you set it with a dB control to determine the parts of the signal the compressor acts on.
So first we say 'a compressor' because it's some abstract compressor, ok, then author says 'the compressor' like it's something specific, but it's still some compressor that aren't even on my or author's computer.
And the same with the other mentioned things: 'the level', 'the threshold', 'the signal' despite they wasn't even introduced. Btw, 'a dB control' doesn't have 'the' for some reason.
My only idea is that once a compressor is introduced, we imagine it and all of its parts as real things.
- Is this sentence correct?
In most sounds, the transient is the loudest moment in the signal.
As I understand, without 'In most sound' it would be 'a transient is the loudest moment in a signal', but 'most sounds' makes it specific?

Thanks for your help!
