I am new to the forum, but love what Sitter and you folks are doing here. I have a sweet set up: Mac Pro, 2 Dual-Core Intel Xeon, 2 X 20 inch Cinema displays, a pair of Mackie HR824, an Apogee Ensemble, a MCU, C4 and a couple of nice AKG mics. Can life get much better? One thing that I havenâ??t done is acoustically treat my studio space. In Oct 06 I was brand new to all of this, and for the last year I have been studying Logic Pro and am just now starting to bring my compositions to the mastering stage. I have been studying a few books on mixing and mastering and read that a Real-Time Analyzer, Pink noise, a 31-band graphic equalizer and a calibrated microphone can compensate for acoustically treating a room. This is what I did. I plugged my AKG C414B microphone into my first Audio Track and I then inserted an AU 31 band EQ and the Logic Multimeter. On the second track I inserted the test Oscillator for my pink noise. In record enabled mode I was able to pick up the pink noise on my mic and adjust the EQ to get a flat analysis on the Multimeter. I then saved the Audio Units EQ setting for my room. My question is, did I do it right? Do I then put the AU EQ on the Out 1-2 track? What about mastering? Do I use the same EQ setup on Waveburner. I still having trouble with a burned AIFF file that sounds good on a Car stereo. Sorry to be long winded.
