if i put the shape slider to +10 and raise the volume on the bass slider will it change the entire shape, meaning cut some lower frequencies as it amplifies the mid range ones? or does it simply add gain like an eq?
Hi Hydro!
The Bass Boost algorithm is a multi-stage Parametric EQ with intelligent protection limiting. The Boost/Cut sliders affect the amount of Boost / Cut for all the different stages.
The Shape slider affects the frequency region of the boost / cut. If Boost/Cut is set to 0, Shape has no effect.
If you turn shape UP (positive values), the bass boost will affect higher frequencies (mid bass) as well. If you turn it up even more, it will affect lower frequencies (sub bass) less, and higher frequencies more.
If you turn shape DOWN, the frequency center will lower (that is, affect sub-bass more). If you turn shape down even further, it will center around 50hz, and also start narrowing (lower Q-value) – for that extra-special thump suitable for booty-bass music among other genres 😉.
Hope this clears things up. 😉

A frequency graph for this function would surely help in mentally visualizing the boost/cut responses for various slider positions. 😉
Visualizing? I don’t know man – I usually listen with my ears 🙂.
Actually, the hard part about visualizing is that it’s not just one function, and it’s also not a static function, but dynamic. Part of the boost happens before the multiband compressor, which means the boost will be program-dependent.
One way to make a graph (even if it won’t be completely accurate) may be to play a slow sweep tone, log 20-20000hz, at a low level (maybe -20dB) through Breakaway, and with Range and Power set to minimum.
This way, the compressor will not affect it much (if at all), and you could record the output through your sound card, and simply look at the level of the waveform you recorded. Make sure you use Reference Settings for this.
Even with Bass Boost turned off, It won’t be *perfectly* flat due to the multiband crossovers, but it should be very close.

hmmm … yes program dependent boost would complicate things a bit wouldn’t it.
But my request was not for precision, rather a series of curves to better explain the slider position and the relative boos/cut/Q responses they present using a fixed or normalized input. Kind of like the graphs shown for parametric eq’s.
But you’re right the ears really do the visualizing…
