Unbelievably, some "mastering engineers" have been known to deliberately clip the track in pursuit of loudness, often at an ADC stage, and then turn the level down a fraction so it doesnt clip on playback. unfortunately, lots of DACs will produce inter-sample peaks under these conditions, which leads to that awful sound.
> Pretty sure that first MGMT album clips all over the place.
I haven't heard their first album but I'm surprised at this. In my experience, most indie acts have greater creative control over mastering and just about every indie act I listen to (with the exception of some of the heavier stuff) is very light on the "loudness". By contrast, some of the more "pop" stuff I like, even songs that should be clean and distortion free, are unnecessarily jacked up way past the redline. A great example is John Mayer's "Heavier Things" album, with clipping and distortion on the lightest, cleanest tracks, and it gets worse with each of his albums after. It's frustrating because I know he's a brilliant musician who knows better, but I imagine it's the label who has the final creative control over what sound is heard on the CD.
