Why Hang Loose Convolver?
The purpose of HLConvolver is to determine one's preference for one eq filter over another while listening to music using speakers or headphones.

If you are eq’ing loudspeakers and headphones, and who isn’t these days, how do you know if the eq sounds better or worse than with no eq? Or how do you know if Filter A sounds better or worse than Filter B? There is science behind how this works which is designed into HLConvolver.

Hang Loose is designed to switch between level-matched "eq" filters in real-time with no audible gaps or artifacts. HLConvolver’s design is based on two scientific principles when it comes to A/B comparison testing in audio.

Fast and seamless switching of filters satisfies the brains processing of short-term audio memory called echoic memory.

"Echoic memory is the sensory memory that register specific auditory information (sounds). Once an auditory stimulus is heard, it is stored in memory so that it can be processed and understood."

Summarizing the science, echoic memory lasts between 1 to 10 seconds. This is "why" the requirement for fast and seamless switching between filters (and bypass) so one can focus on the full echoic memory during the first 10 seconds of a filter switch (or bypass).
Fast and seamless filter switching
Level matched filters to bypass level
Hang Loose is designed so that each Filterbank has its own gain slider to adjust the level of the filter. This allows one to "level match" each filter to another (and bypass) either by ear or instrumentation assisted using pink noise and a sound level meter.

Summarizing the science, if one sound pressure level (SPL) is higher than the other, almost always the higher level "wins" as "better" sounding. This is due to our ears nonlinear frequency response often referred to as the Fletcher Munson (now ISO 226) equal loudness contour curves.

Simply put:
· at lower listening volumes mid-range frequencies sound more prominent, while the low and high frequency ranges seem comparatively quieter.
· at higher listening volumes the lows and highs sound more prominent while the mid-range seems comparatively quieter.

Therefore, our ears interpret louder sound to have a fuller bass and more clarity on the top end. Conversely, we perceive quieter sounds to be thinner and duller. Even an increase of 1 dB SPL can create the illusion of “better” sound.
This is "why" filter level matching is critical in determining one's filter preference.
The "Autogain" feature calculates the DC gain (section 2.2.4) of the FIR filter and automatically applies that to the filter gain slider as a starting point for level matching the filters. Depending on the frequency response of the FIR eq correction filter will determine how much gain is to be applied during the level matching procedure. This is due to equal loudness contours previously discussed.

The "Master Trim" level controls the overall gain of the convolver. The idea is to "level match" the gain of the filters with the "bypass" level. Using the "Output Level" meters, one can ensure no clipping is occurring in the convolver. If clipping occurs, one can reduce the master trim level so the bypass level goes down and one can increase the Filterbank gain slider level so that no clipping occurs, but now the filter is level matched to the bypass level.

The "Presets" allows one to store up to 6 Filterbanks per preset. Dozens of filters can be available at one’s fingertips for comparison. Or simply a "preset" for a particular media like music versus movies or for a genre like rock versus orchestra or a particular headphone or speaker setup.

Standalone application and plugin modes of operation on multiple operation systems allows Hang Loose to operate on system wide audio and application specific audio across the broadest range of audio sources possible.

Conclusion
Hang Loose Convolver allows one to compare filters in a scientific way without having to mess with the mechanics of level matching filters and seamless filter switching. It is easy to operate on the widest range of audio sources which allows you to "hang loose" and focus on which filter you prefer.

Please take the time to read the operations guide to get the most value out of Hang Loose.
I hope you enjoy it!
