Of course you can.

If you are combining multiple files into one queue and getting a different result than when the system combines multiple audio queues, then there is either something wrong with your code or your perception. I suppose it's possible that you're listening on a laptop, and the built-in audio compensation is reacting differently, although that is unlikely, but if you use the digital outputs or a well-known audio interface, then you should be able to get identical results either way. There is a Playback Gain for each Audio Queue, have you examined these? Unless the overall graph has some kind of dynamic plugin inserted, there should be no automatic gain with Audio Queues.

can I reach the same volume with one audio queue as I can with multiple queues?

When I run multiple audio queues (for example playback multiple audio files at the same time), I can reach a higher volume than if I just added the buffer signals into one audio queue (which clips).
Is there any way to achieve higher volumes with just one audio queue? Like, is there a volume setting that I can increase?
