What the bloody heck is "mid-bass"?
I always love the goofy adjectives and language that my fellow audio-enthusiasts come-up with.
I realize "mid-bass" isn't a new moniker, I have old Stereophile magazines from the early 90's that use it, I suppose that was the first time I came across the term. But I have no idea exactly what "mid-bass" is as it is most commonly used.
So what frequency range are we referring to when we say mid-bass? I'm thinking it's probably something around 60Hz to 110 Hz or something?
Maybe a bit higher? Is there a "high-bass" as well?
Where does "bass" end and "mid-bass" begin...
What other names are there in the musical spectrum? :)
The chart's sub-heading...
...says it all, "fundamental frequencies"...
The upper limit of 18-20kHz includes the harmonics and overtones which provide our ears info re: the type of instrument producing it's unique sound.
There are what is referred to as fundamental waveforms(square, sawtooth, sine, etc.). The apparent character or envelope is shaped by the instrument producing them and further contributes specific harmonic frequencies allowing identification of them. Obviously, there are things such as attack and decay, but the fundamentals and upper harmonics are the most salient features. You can pluck it or you can bow it, but a violin still "fundamentally" sounds like a violin.
Additionally, access to these upper frequencies is what provides for the "air" and such to the sound we preceive in our audio reproduction systems.
