Note that this is the complete settings list as of 30 April 2015. Review note: You might assume from various reviews that certain headphones - particularly the smaller, closed, on-ear variety - that are described as sounding 'constricted' or having a less-than-ideal soundstage, are basically unfixable with sonic bandaids such as EQ. Not any more. Most such headphones - as long as their response is within the audiophile 'ballpark' (i.e. not recessed or emphasized more than ~6 db) - can be tuned with this app to make the sound more 'open' with a much better soundstage, and with a smoother treble that's free or harshness and other irritations. This simple app has changed my life. Having owned about 90 different headphones (13 currently), I've struggled with equalizers in iTunes, Foobar2000, and the built-in i-device settings such as 'Bass Reducer' and 'Treble Reducer', in an effort to suppress peaks and other resonance effects in my headphones. I don't have a need to change the basic signature of a headphone from, say, dark and bassy to something lean and light - I just need to make the (usually) small adjustments to correct the irritant factors, so I can enjoy the unique flavor that each of these headphones provides. The Audioforge Equalizer app has 7 settings that correspond to 'bands' used in many other equalizers, but where most equalizers' bands are fixed at a center frequency such as 30 hz, 60 hz, 120 hz... and so on, the Audioforge Equalizer settings can be set to any frequency, and then to any amplitude plus or minus. This flexibility allows me to equalize a new headphone in 0.5 to 1 hours time, depending on the severity of any irritant factors as noted above. The basic settings can be worked out in 30 minutes or less, then various listening tests and comparisons to other headphones help to fine-tune the results. People who use the Audioforge Equalizer can read the technical manual and then determine whether they wish to experiment with the parametric features, i.e., shaping the width and slope of each adjustment curve to make corrections that are more precise. I don't do that. Since the equalizer displays a summation curve that combines the total effect of the 7 individual settings, I can see what I'm getting rather than what I asked for - i.e., when you push up 4 khz by 6 db and push down 5 khz by 6 db, the result is an increase of about 2.7 db at 3.7 khz and a decrease of about 2.7 db at 5.3 khz. You can certainly do better with parametric adjustments, but I've found that the improvements I get using the simple frequency-and-amplitude method are dramatic enough, and any further efforts incur greatly diminishing returns. I run a series of test tones before and after equalizing to be certain that I'm getting to the right targets, then I listen for overall balance to see if I need to increase or decrease a range of settings to achieve the proper balance, and then I perform the music tests and comparisons to other headphones to make sure the final sound is "in the ballpark", hi-fi-wise. I don't intend to make any of my headphones sound the same as another headphone, which isn't practical for a host of reasons, but there comes a point in the equalization process where the sound is just right for that headphone. It's not something I know in advance, and even then there may be a further change if subsequent listening points up one of those irritant factors that was corrected almost perfectly the first time, but not quite. Listed below are settings that I've worked out for several of my headphones. Note that the amplitude of many of those settings (i.e., plus 8 db, minus 6 db and so on) are not the actual corrections - refer to the above explanation of how the equalizer's summation curve works.
