Thanks for the response. I don't understand what it has to do with the speakers. I record with a direct line from bass into my DAW and therein I was looking at the waveforms. Not sure what the speakers have to do with it Do you know why waves are not symmetrical. I have noticed this too in my...

How is that different to my interpretation? That is why i was recording my bass looking at the waveforms... to see the polarity

They all seem the same to me. Here are 3 pics. one of the wave when slapping down on the strings you can clearly see positive leading edge but when plucking the strings it seems different. I will add the low E string waveform pic and the high G waveform pic so you can see

Thanks for the reply. When playing the bass normally with my fingers the "leading edge" of the waveform is negative but before playing I actually did a test and hit down on the strings with the palm of my hand. The reason why I did this is because I wanted to see what the polarity was in my DAW...

Sorry if this is the wrong place for this question. I am a musician and recording engineer trying to learn about why my bass guitar recordings sometime appear with the waveform going up first (positive polarity) and other times going down first (negative polarity) in my DAW (digital audio...

Thanks, it is good to have a plan B :) Do you think my plan is OK though? Can you see if it has any flaws in it?

Not really, I just need humidification and maybe some cooling in summer but because I am in the basement but it really doesn't get too hot down there. I was going to use a mini split system which will be completely independent to the ventilation. My plan is to have the supply register close to...

On an acoustic forum where I have done most my reading, the advice is to let the duct run straight before reaching the register/grille. So there can be bends in the duct work but not too close to the opening. Although I must say that I am a bit confused by this because I only have two options...

Thanks, I was planning on having the return register at around 75% of the room length as in the diagram. Do you think 1 exhaust vent is sufficient for a 20 X 13ft room? The other option is to use something like this (see pic). This way I could put two registers in the room at different location...

Ok great! And does it matter that the path of air has to squiggle through all the baffle boxes. I am sure they create static pressure but from a physics perspective, can the fresh air intake suffer as a result of the static pressure caused by the silencer/baffle boxes? Here is a picture of one...

here is a side view of the room where I plan to have the exhaust duct. The other side is identical but just without a fan. I am not sure if I should put a fan on the other side. On an acoustics forum they said this may cause "aerodynamic stalling" if you use two fans and that it is best to just...

yes exactly, there will be a hole on either side of the room with ducts attached to silencers/baffles to not let the sound inside.

There would be two holes in this airtight soundproof room. One hole on one side of the room with an exhaust duct and fan attached onto the outside of it and another hole on another side of the room with only duct attached to the outside of it. Would this work? Here is an aerial view plan of my...

Hello! I am building a recording studio which will be air tight and will need fresh air intake and stale air exhaust. I have a general question regarding which is better, using one or two inline fans for the job? I was told that that you could have one fan on the exhaust duct which can pull out...
