Well , we might have just find the grandaddy of all audiophile euphony apps , perfect for the most of import music snob in your life : you .
Of course , if you give care about sound caliber , you already have nice headphones .
Canopener for iOS ( $ 4 ) , is about what happens decent before the sound leaves your iPhone , but before it gets to your “ ear goggles . ” It ’s a medicine participant app , meaning that its developer , Good Hertz , is go for you ’ll utilize it instead of Apple ’s own Music app . This also means it does n’t work with streaming music or subscription service — just your own downloads . Other than that nitpick , quite honestly , we can not think of a individual reason you would n’t wantthis app , if you care about sound quality .
It looks good . Great invention . But that ’s not what this app is for . fortuitously , Good Hertz LLC , the company behind this app , whose father , proprietor , and run developer Devin Kerr is a demented sound recording scientist , producer , instrumentalist , and legal engineer who really knows what he ’s doing .
This app almost does too many thing for us to note , but we ’ll essay , below . To summarize its collection : This isthe iOS sound timber appfor people who do n’t believe in lots of weird , notional processing to add together “ quad ” to a strait . CanOpener‘s approach is anythiung but snake oil — it ’s science .
The most canonical thing this app does is sum crosstalk to your headphones — as much or as footling as you want . Crosstalk is what makes speaker unit vocalize different from earpiece , because a piddling act of the left speaker gets to your right spike , and a little bit of the veracious speaker puzzle to your leftover ear — thus the term “ crosstalk . ” Normally , earphone eliminate all crosstalk ; CanOpener puts it back , which you ca n’t hear in this blog Charles William Post , but the ascendancy depend like this :
Meanwhile , a “ mastering - grade baxandall equaliser ” let you sculpt sound flop from the spectrogram . First you see the sound :
Then you sculpture it with your fingers :
Or choose a preset :
CanOpener also chase your current SPL ( heavy pressure level , more commonly bonk as intensity ) , as well as your lifetime mediocre SPL , and the act of moment of music you have listened to in the app :
Devin Kerr , player , couturier , and possessor / developer of Good Hertz , tells Evolver.fm that he ’s noticed some interesting patterns in how people are using the app so far .
“ We have n’t complete any conventional data analysis yet , but one thing we are very pleased with so far with is the modal listening level that most of our users are using CanOpener at , ” said Kerr via email . “ Only around 10 percent of our users have average listening grade over 85 dB SPL ( which is the generally accepted doorsill where sense of hearing damage is potential ) , and the highest percentage of our users have average hearing levels between 65 and 75 dB SPL , which we consider ideal . At least preliminarily , this datum suggests that when using CanOpener ’s Dosimeter , user may be more aware of their listening levels and thus choose sizeable volumes . ”
Moving on , you may choose your headphones in the app to verify it ’s assure the preferences properly for your mannequin . If yours are n’t included , you’re able to dig up the specification and add them to the app manually :
This is the first music app we have catch , we think , that let in a bibliography citing the sources upon which its science is based :
CanOpenerdoes all of this and more , but one thing it does not do is apply some weird “ spatializer ” algorithm or whatever to all of your music , the way many apps that purport to improve sound character do .
Evolver.fm follow , tracks and canvas the medicine apps scene , with the belief that it ’s crucial to how humans experience euphony , and how that experience is evolving . ( Top range : iMarin )
