.....or anyone else in the know: Preface: Back in my younger days (I won't say how long ago that was... ), I used to work out alot at what was then Presidents Health Club. One of the trainer guys was telling me that their term for bulky, well-defined triceps was "muscle-cuts". I have adopted this term in describing the lower end of the audio spectrum. In looking at numerous FFT graphs of great sounding, punchy tunes, I have noticed that the low-mid (I mean, mud) region (~130Hz-400Hz) is well "cut". It looks as if it were intenionally and deliberatly carved out to look/sound a particular way. In other words, the shape of the graph in that region has very defined slopes. The term "muscle cuts" applies here as these freqs. along with the bottom end really do provide the muscle (punch/drive) of the song. If the bottom end is flabby, the whole song sounds flabby. OK - Understanding that this spectral region can make or break a tune.... ....how do you big boys do it? ("cut" the bottom end)...EQ?, M/B compression?, What? Is it a secret? We little guys would really appreciate some hints from you heavyweights! Thanks.
