iPadOS 13.1.3 and Playgrounds 3.1(1084.29)

Heey, i try to use AKMixer, in last version of AudioKit, and i follow steps to play my mix, but, i can`t play.
this is my code:

let a1 = try? AKAudioFile(readFileName: "x.mp3", baseDir: .resources)
let a2 = try? AKAudioFile(readFileName: "y.mp3", baseDir: .resources)
let a3 = try? AKAudioFile(readFileName: "z.mp3", baseDir: .resources)

let mixer = try? AKMixer([AKAudioPlayer(file: a1!), AKAudioPlayer(file: a2!), AKAudioPlayer(file: a3!)])

AudioKit.output = mixer

do {
     mixer?.volume = 1
     try AudioKit.start()            
}catch {
     print("Fail!")
}

the result of this code: no sound comes out and following log message:

2018-07-19 17:18:22.250612-0300 AKForever[306:14884] [DYMTLInitPlatform] platform initialization successful

I am trying to run AudioKitPlaygrounds. Building an running the Hello World sample I get the following error messages:

I get the following error:

Module compiled with Swift 5.0 cannot be imported by the Swift 5.2.4 compiler: /Users/alexgawley/Documents/code/iOS/AudioKit/Playgrounds/Xcode/Pods/AudioKit/macOS/AudioKitUI.framework/Modules/AudioKitUI.swiftmodule/x86_64.swiftmodule

AkSliders in Playgrounds give this error. Which init method shoud I use?
Fatal error: Use of unimplemented initializer 'init(property:value:range:taper:format:frame:callback:)' for class 'AudioKitUI.AKSlider'

For example, this init is called in Playground.

AKSlider(property: "Modulating Multiplier",
                 value: fmBank.modulatingMultiplier,
                 range: 0 ... 2
) { multiplier in
    fmBank.modulatingMultiplier = multiplier
}

Xcode and Pod versions:
Xcode 12.2

  • AudioKit/UI (= 4.11.2)
• AudioKit/Core (4.11.2)
• AudioKit/UI (4.11.2):
  • AudioKit/Core

Here I am trying to display panning parameters inside my customised view with slider. I could run your code for,

addView(AKSlider(property: "Speed", value: effect.speed, range: 0.1 ... 25) { sliderValue in
                         effect.speed = sliderValue
                   })

But I need to run this inside my custom view and slider. How could I do this?

Sorry if this is something obvious but i'm struggling to get playgrounds to build.

I downloaded the latest version of the playgrounds zip from the git repo.

Did pod install (it installed audiokit 4.11.2)

Opened workspace and pressed build.

Received this build error

I changed the deployment target to 12.0, and then got these AKPlaygroundUgens issues.

Any help would be really appreciated, thanks

So I must to doing something simple wrong, but in the above you can see I've got it building (build succeeded message in the header there) but I still see the prebuild error No such module 'AudioKitPlaygrounds'

I had to switch it to "Rosetta" to get the build to succeed. I'm on an M1 MacBook Air.

I'm unable to build the playground on Xcode 12.0.1. I get this error message :

"{home"/Documents/code/Playgrounds/Xcode/Pods/Target Support Files/Pods-AudioKitPlaygrounds/Pods-AudioKitPlaygrounds.debug.xcconfig: unable to open file (in target "AudioKitPlaygrounds" in project "AudioKitPlaygrounds")"

Any ideas?

The drawbar playground is misleadingly simplistic. The AKOscillatorBank stop-note signals for the drawbars collide with those of additionally-played notes. I figured this out the hard way when trying to adapt the example to use with a MIDI controller. Hold key X, then press and release key Y, and all of the overlapping notes of key X turn off.

(I've been trying to construct a workable alternative, but I'm fairly new to AudioKit and haven't mastered the finer points yet. I suspect I need to get a better handle on AKOperation?)

Is there a compatibility issue? Current playgrounds version: 3.3.1
It says:
INVALID PLAYGROUND BOOK
Audiokit.playgroundmodule: Unable to open module.

The error message is something like:

expression failed to parse, fixed expression suggested:
#sourceLocation(file: "Introduction and Hello World.xcplaygroundpage", line: 1)

I get an error when trying to open the playground book in the latest Playgrounds app.

Some of the controls are off-screen and/or cut off.

This isn't a technical issue with AudioKit or this .playgroundbook themselves–it's more about clarifying some beginner questions I have 😃.

Well, I've just started playing with AudioKit's APIs–and I'm lovin' them all–aiming to implement a .playgroundbook project which consists of allowing readers to design and visualize–e.g. through { sine, square, sawtooth }waves form plots– musical algorithms making use of audio streams generated with math functions–e.g. the following code:

func sineWave(t: Double) -> Double {
    
    func sin(α: Double) -> Double {
        return Foundation.sin(2.0 * M_PI * t * α)
    }
    
    return sin(α: 440.0)

}

where the second returned function gets run 44000 times per second and returns a Double between -1 and 1 which represents the wave amplitude.

After reading the APIs–and observing a few regular playgrounds of yours–I noticed I should use a few classes–mainly responsible for oscillators–e.g.:

• AKOscillator
• AKOutputWaveformPlot

Just like you did in awesome exemples here:

But, what you said here scared me a bit:

[...] *It is not a complete copy of AudioKit's functionality and only contains a fraction of the playgrounds available from within Xcode. There are no synthesis or analysis playgrounds [...]

My point is: is there any known issues related to using the APIs used here in .playgroundbooks? Would AKOscillator, AKPlaygroundView, AKOutputWaveformPlot–and others–be suitable in such special kind of playground? Have you tried anything like this before? Any suggestions?

Also, I'm kinda a newbie with Playground (Book)s as well 😭

Thanks!
