Ok so its pretty rare that I post anything and for that I am sorry to everyone, but I have something on my mind that I know has been discussed here before but it just seems that I am having a hard time capturing. Depth is a sticky subject and really can be up to the listener to interpret what level of depth/3d feeling the mix creates. I understand that classically the idea for creating depth for an instrument in a mix would be to use reverb and then to possibly place a low pass filter on the track to remove some of the highs to create the image that the object/instrument sets farther back in the mix. As a alternative to this method some people use delays set for a really short time in the tempo of the song to create a "wet" feeling but to allow the instrument to still be more present. Also the an eq can be used to create a more forward feeling by boosting highs and high mids and possibly reducing the lows. I know there is a whole lot more to the idea of creating a 3D feeling to a mix, but it seems to be difficult to achieve. So I have been working on this band for a while, I just finally finished with them and got a chance to go with them to have their CD mastered. They went to Studio B in Charlotte NC, with Dave Harris and he really seemed to bring the mix alive to me. It seems that what I had done for the mix was flat/ not as 3D as how he made it sound. So basically what I am getting at is what is the tips or tricks that everyone has for creating depth in a mix?
