ios - Track Frequency from Microphone using AudioKit -


creating swift-ios project tracks audio frequency microphone. using audiokit 3.0 framework. have following code working in xcode simulator when run on device doesn't appear reading microphone signal correctly.

    // prepare microphone     let mic = akmicrophone()       // connect microphone high pass filter     let mixer = akmixer(mic)     let highpassfilter = akhighpassfilter(mic)      // set parameters of hi pass filter     highpassfilter.cutofffrequency = 7000 // hz     highpassfilter.resonance = 0 // db       let tracker = akfrequencytracker(highpassfilter, minimumfrequency: 7000, maximumfrequency: 8000)     highpassfilter.play()     audiokit.audiooutput = tracker     audiokit.start()      akplaygroundloop(every: 0.1) {         let freq = tracker.frequency         print(freq)     }

i use code audiokit 3 , works fine:

    let mic = akmicrophone()     amplitudetracker = akamplitudetracker(mic)     aksettings.audioinputenabled = true     audiokit.output = amplitudetracker     audiokit.start()     mic.start()     amplitudetracker.start()

this akamplitudetracker situation same you. try aksettings.audioinputenabled = true

hope helps.

r - Update two sets of radiobuttons reactively - shiny -

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
