comyar / tuningfork Goto Github PK

I am wondering if there is a way to filter the sound to only a specific instrument (e.g. piano, guitar or vocal)?

Does not run under OS X 10.11.1 complaining it cannot find CsoundLib.framework. If I check in /System/Library/Frameworks it is not there.

I noticed AudioKit is compatible with tvOS, if TuningFork is compatible too it would be great to add support in pod file even to tvOS too

Hello! I don't know what's wrong with my code but I'm receiving this output:

0dBFS level = 32768.0
Csound version 6.05 (float samples) Sep 18 2015
libsndfile-1.0.26pre6
    2015-11-03 10:22:25.253 TuningForkTest[260:15546] 1 MIDI sources
2015-11-03 10:22:25.258 TuningForkTest[260:15546] MIDI source 0: Session 1

This is my code:

import UIKit
import TuningFork

class ViewController: UIViewController, TunerDelegate {

    let tuner = Tuner()

    override func viewDidLoad() {
        super.viewDidLoad()
        tuner.delegate = self
        tuner.start()
    }

    func tunerDidUpdate(tuner: Tuner, output: TunerOutput) {
        print(output.pitch)
        print(output.octave)
    }
}

I am trying build a UI around the values of output.frequency, but it seems like the values I get to work with are jumping. How can I get smoother values? Tuning a guitar with constantly jumping values is difficult. Thank you!

Followed instructions to use TuningFork in project by adding line in cocoapods and installing but doesn't compile in XCode 8.3. Error saying to check dependencies:
“Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.
If I follow this conversion to current swift syntax, then I get 119 errors in Chronos-Swift and Tuning Fork which are locked files.
Please help. I've heard TuningFork is great, but obviously no good with these errors!

Frequency Jumping value Issue:

First of all, thank you to all contributors to make such a beautiful library for audio signal processing.
I am working with the TuningFork in Swift language.
I am getting Frequency values using these lines of source code:

` let tuner = Tuner2(threshold: 0.07, smoothing: 100)
tuner.delegate = self
tuner.start()

func tunerUpdate(frequency: Double, amplitude: Double, output: TunerOutput?) {
print(frequency)
DispatchQueue.main.async {
self.frequencyLabel2.text = "(frequency)"
self.frequencyLabel.text = "(output?.frequency)"
}
}
`

I tried to play with the smoothing factor as well, but didn't get the expected result. I know underneath of it, it uses Audio kit class to fetch frequency.
I'm playing constant tone of 440HZ using Online Tone Generator
I'm getting following output on the console:

It is not giving me that much accurate frequency values as I am getting in TE Tuner application.
Here is an example of both application with the same frequency:

Audio kit is not compatible with swift 4. please update

Swift compiler error in TuningFork.swift

Module compiled with Swift 3.1 cannot be imported in Swift 3.2

App is constantly at 100% and over CPU usage. Any way to reduce this?

Waiting on AudioKit migration to Swift 3.0
