Tone Framework

A Swift package for working with AudioKit and allows to perceive and filter tones (frequencies)

Requirements

• Swift 5.3+
• IOS 13+

Usage

---

import ToneListen

// Instance tone framework by passing client ID
let toneFramework = ToneFramework(clientID: {{ Your client ID }})

//Start listen service:
toneFramework.start()

//To stop service:
toneFramework.stop()

//If you need to be notified when a valid tone was caught, you will need to subscribe to 'notificationName' from NotificationHandler:

// By publishing this property we can ensure that our subscriber (notificationName) will be
// re-rendered when the property changes (i.e. whenever there's a new notification)
@Published var newNotification: String? {
    didSet {
        guard notifiedValue != nil else { return }            
    }
}

notificationSub = NotificationCenter.default.publisher(for: NotificationsHandler.notificationName)
            .map { notification in notification.object as? String }   // Transform the notification into a simple string
            .assign(to: \notifiedValue, on: self)  // Assign the msg to a property using a keypath

// 'notifiedValue' saves an URL or PhoneNumber (string), depending what tone was caught. 

NOTE:

You need to add "Background modes" capabilites to your project to allow using microphone and location services in background.

Also you need to add "frequencies_table.json" file to your project.
