描述：By request, first three minutes of http://www.freesound.org/samplesViewSingle.php?id49801 (20080302.guadiamar.midside.flac) with original Mid/side encoding. That is, the left channel has the sounds captured by the middle mic (Sennheiser MKH60), and the right channel has the sound taken from the sides by figure8 Sennheiser MKH30. Both mics were plugged into a Shure FP24 preamp, recorded with Edirol R09As for the content, you'll listen to weird funny sounds produced by birds (male Coot calling, fighting/splashing around, Sand Martins, Swallows, Little Greb, Mallard). Sheep bleats in background.
