Here’s a simple, quick example: Let’s say you’re recording some hip-hop and want the trademark heavy bass. You’re using Reason or FL to create a beat. You start with a string line that’s been in your head for days. All is well so far. You then put down a nice, crisp hi-hat. Still fine. Now you move on to an 808 kick/bass sound. You hear it, but it doesn’t push well, so you turn it up. It still doesn’t sound like it does in your head, so you crank 60 or 80 Hz up a few decibels. Still not enough. You crank it a little more. It gets a little louder, but you heard a little crackle of distortion, so you back it off until it sounds clean, then you move on to your snare. Fast forward now to a point where you love the beat and you want to cruise around in your car and critique and enjoy it. You pop it in, turn it up and BLAM! distortion and HUGE, OVERPOWERING BASS EVERYWHERE! Obviously, this is not acceptable. This is caused by your tiny laptop speakers’ inability to produce bass, making you turn it up louder than it should be.
