| 描述： | This was an interesting set of waves to record, mainly a test just to see what would work and what would not. Recorded on a Marantz PMD661 (super mod from OadeBrothers) with 2 Rode NT1A mic's at 120 degree mic angle/20 cm's apart/SRA 42 degrees (kind of a narrower Olson stereo technique, which is 20cm/135 degrees/SRA 38.4), and about 24 inches off the ground. Also used 4inch long fur on the wind cage surrounding the mics, an enclosure I custombuilt to block the wind from the mics (kind of resembles a deerfeeder with 3 telescoping legs). It was recorded on Nov. 15, 2010 in the late afternoon at McFaddin Beach, about 12 miles west of Sabine Pass, Texas. Not too hard of a place to find since the highway that once connected Sabine Pass to High Island (Hwy 87), along the Gulf of Mexico, is no longer open too many hurricanes. I had difficulty with the waves on this day (no hurricanes, though). Winds were a steady 10 mph and offshore (meaning they were blowing from shore to water). You'll also notice a very distant but low, eerie vibration when the waves crash. I haven't figured that out yet. If you use a narrowband EQ in your software, and push the band's volume way up, you'll notice the sound even more. Very eerie. I assume it's the vibrations in the sand from the massive miles of waves continuously falling over. I also tried to enhance the lack of quiettoloud dynamics inside Wavelab using the free plugin, IQ4Gui (I like it far better than the Sonalksis DQ1 , but not just because it's free IQ4Gui allows you to make much more dramatic settings than the DQ1). The problem was that there was a constant roar the waves weren't getting quiet enough after crashing to where the detail of the aftercrash wavelets, which continued onto the beach another 20 feet, could be heard. I also read online in different sites that wind tends to be the main thing that generates waves in the Gulf of Mexico, rather than deep swells. Swells travel miles to get there (like on the East and West coasts) and continue to move even after the wind stops blowing. So, to give these waves a little help, I used the IQ4Gui plugin in downwardexpander mode. This mode basically causes the quiet sounds to drop even further in volume (or, to get quieter) when they drop under the threshold you manually set. Finally came up with what you hear in this segment, which is taken from the longer hourandtwentyminute recording. I discovered that I really needed to have been further out in the water to where the mics would be closer to the wavelets so as to capture the detail of their higher harmonics. Sadly, that part is hard to hear in this wav file :(. I was set up maybe 25 feet from the bulk of the waves crashing, right at the outer edge of the wavelet area. Given the massive saturation of harmonics, from the huge number of waves crashing up and down the coastline, it would have been better had I been out in the water with mic stand and recorder to zero in on the higher frequencies and detail of the wavelets, plus also those of the waves when they first fall over and you hear that initial crashing sound. Another reason for getting in closer is based on my understanding of the work of Michael Williams regarding the Stereophonic Zoom principal. This principal is essentially a technique for how to experiment with setting different spacings and angles of your microphones when recording in stereo so that the sounds in the image dont end up crowding to the outside of the playback image, or into the middle of the image too far complicated stuff, but very fascinating. Interesting graphs for seeing ahead of time how to stereomic stuff so that when you play your recordings back they spatially and positionally translate exactly like you miced them.
