You can add an equalizer implemented by an audio unit or AVAudioUnit (such as AVAudioUnitEQ) by adding it to the processing graph between |

Assuming your app manages the class MyPlayerController {
let player: AudioPlayer
var equalizer: AVAudioUnitEffect! = nil
init() {
player = AudioPlayer()
// Insert 4-band equalizer between the player and main mixer nodes
player.withEngine { engine in
let mainMixer = engine.mainMixerNode
guard let mainMixerInputConnectionPoint = engine.inputConnectionPoint(for: mainMixer, inputBus: 0) else {
// Handle error
}
self.equalizer = AVAudioUnitEQ(numberOfBands: 4)
guard self.equalizer != nil else {
// Handle error
}
engine.attach(self.equalizer)
engine.disconnectNodeInput(mainMixer, bus: 0)
engine.connect(self.equalizer, to: mainMixer, format: nil)
guard let mainMixerInputNode = mainMixerInputConnectionPoint.node else {
// Handle error
}
engine.connect(mainMixerInputNode, to: self.equalizer, format: nil)

No and I don’t see SFB in the target of the simpleiOS App. I included a screenshot of both my project and the simpleiOS App.
Thanks for the help¡

I linked them. The errors stopped and the bridge-header recognizes SFB, but my main player; UniversallyPlayer.h doesn’t recognize the SFBAudioPlayer.h.
Thanks!

Well I imported the #include <SFBAudioEngine/SFBAudioEngine.h>
And that worked! So now I have access to the player.
I’ll let you know if I am able to play a track.
THANKS!

For some reason it stopped recognizing the #include <SFBAudioEngine/SFBAudioEngine.h>
I tried to import by dragging the entire folder into my project but I get the “Built External…” is it supposed to be an external built?
I followed this exactly as it is:
Building SFBAudioEngine
git clone https://github.com/sbooth/SFBAudioEngine.git --recurse-submodules
cd SFBAudioEngine
make -C XCFrameworks
Then dragged the entire folder onto my project.

I recommend building SFBAudioEngine.xcframework as described in the README and then copying the resultant XCFramework to your project's directory. Then you can add it to your project like any other framework.

We’ve tried everything. We created a new project with practically nothing in it and we still get the same file not found error.
Can you let me know in what way you want us to import the engine?
If I put the engine in my projects folder, it auto appears in the project.
For iOS, you state:
"When compiling iOS targets against SFBAudioEngine it is necessary not only to link to and embed SFBAudioEngine.framework, but the XCFrameworks used by SFBAudioEngine as well since iOS does not support umbrella frameworks."
Can you clarify how you want to “link” as well as “embed” the engine.framework?
And how to do the same with the XCFramworks?
Because if I do what you are asking, I get a Dupplicate Framework error. And if I don’t, then I get the Not Found error.
Thanks, Dorian

This discussion has definitely gone off-topic from the initial question about equalization. Are you compiling for macOS or iOS? Did you try using the SimplePlayer projects as references on how to get things working? Please create a repository showing the problem because at this point I honestly don't understand what you're trying to do. |

I have an iOS music player project that uses the STKPlayer library, which works and has EQ, but can’t play DSD files, so I want to use this player instead. I also want to make the app Mac compatible, and this player has both samples, so it looks like a perfect fit,
Using the sample iOS and Mac work, but if I bring it into the project, then it doesn’t.

So SFB wouldn’t contribute to the RAM getting used up? Any settings that we are not using or something else?We are using Realm, and even if I set it to saving just three fields: songID, songName, and songPath, the app uses RAM at about a gig per 1,000 songs.We are still looking for a solution, but we can’t seem to find what is using the RAM.Any pointers would help.Thanks!Sent from my iPhoneOn Oct 2, 2023, at 9:41 PM, Stephen Booth ***@***.***> wrote:
Handling large libraries is a broad topic with no ready-made solution that I'm aware of. You'd likely need a database (Core Data, SQLite, or something else) to manage the data efficiently. What you store in the database (and how) would depend on your app.

We found that the issue is the way SFB loads all the images to ram. If we leave out the images, Then the app uses very little ram.
How do we tell SFB to not load the images to ram and have it lazy load?
We can save them to the drive and lazy load them.
Thanks,
Dorian

I'm not sure I understand your setup. Are you instantiating a metadata instance for each file in the library? That class should be used to read the metadata and album art from the file, and then it should be copied into some other data store that can handle loading and paging. You could also try getting the dictionary representation and then stripping the album art from that. |

I recommend only reading the metadata once when the file is initially added to your data store and then storing the fields you're interested in. Creating a new instance of metadata for every file at every app launch is going to be fairly slow because of the overhead involved in opening and parsing the files. |

Yes, with the help of AI I was able to figure out how to save to realm and now it used 350MB approx.
Thanks for the help!! I should have this app ready in a couple of months.

Creating a new instance of metadata for every file at every app launch is going to be fairly slow because of the overhead involved in opening and parsing the files.

Ok, now that I know that, we’ll figure it out. Thanks a million!Sent from my iPhoneOn Sep 12, 2024, at 11:32 AM, Stephen Booth ***@***.***> wrote:

Hi, I’m trying to get airplay to work within an airplay popup in the app. Our menu opens fine, and after selecting an airplay device, I’m able to control the volume on the device, but the actual audio output stays in the “build-in output”. If I select the same device from the apple sound menu, then it shows along with the "build-in output” in the menu.
Any ideas?
// MARK: - Device Selection Action
@IBAction func audioOutputSelector(_ sender: AnyObject?) {
guard let menuItem = sender as? NSMenuItem, let device = menuItem.representedObject as? AudioDevice else {
return
}
var dicOutputAudio = [String: AudioObjectID]()
dicOutputAudio["outPutAudio"] = device.objectID
HardwareChange.shared.notifyobserver(objUpdateState: .UpdateOutputDevice)
NotificationCenter.default.post(name: kUpdateOutputAudioDevice, object: dicOutputAudio)
}
// MARK: - Device Menu and AirPlay Setup
@objc func loadAudioDeviceHardware() {
// Monitor for system device changes
try? AudioSystemObject.instance.whenSelectorChanges(.devices) { _ in
DispatchQueue.main.async {
self.updateDeviceMenu()
}
}
// Load previously selected output device
if let uid = UserDefaults.standard.object(forKey: "deviceUID") as? String,
let deviceID = try? AudioSystemObject.instance.deviceID(forUID: uid) {
try? player.setOutputDeviceID(deviceID)
}
// Update device menu and setup AirPlay button
updateDeviceMenu()
}
@objc func updateDeviceMenu() {
devicePopUpButton.menu?.removeAllItems()
do {
let currentOutputDeviceID = player.outputDeviceID
outputDevices = try AudioDevice.devices.filter { try $0.supportsOutput }
for outputDevice in outputDevices {
if let isPrivateAggregate = try (outputDevice as? AudioAggregateDevice)?.isPrivate, isPrivateAggregate {
continue
}
let isActiveDevice = outputDevice.objectID == currentOutputDeviceID
let deviceMenuItem = NSMenuItem(
title: try outputDevice.name,
action: #selector(self.audioOutputSelector(_:)),
keyEquivalent: ""
)
deviceMenuItem.target = self
deviceMenuItem.representedObject = outputDevice
deviceMenuItem.state = isActiveDevice ? .on : .off
devicePopUpButton.menu?.addItem(deviceMenuItem)
if isActiveDevice {
devicePopUpButton.select(deviceMenuItem)
}
dacInfoLabel.stringValue = try outputDevice.deviceUID
print("Device is Available, switching to device:", dacInfoLabel.stringValue)
}
devicePopUpButton.menu?.addItem(NSMenuItem.separator())
} catch let error {
print("Device Not Available, switching to next available device.", error)
}
}
// MARK: - AirPlay Button Setup
@objc func setupAirPlayButton() {
// Initialize and configure the AirPlay picker view
let airPlayPickerView = AVRoutePickerView()
airPlayPickerView.translatesAutoresizingMaskIntoConstraints = false
// Container view to house AirPlay picker
let airPlayContainerView = NSView()
airPlayContainerView.translatesAutoresizingMaskIntoConstraints = false
airPlayContainerView.addSubview(airPlayPickerView)
// Add AirPlay picker to view hierarchy
view.addSubview(airPlayContainerView)
NSLayoutConstraint.activate([
airPlayPickerView.widthAnchor.constraint(equalToConstant: 18),
airPlayPickerView.heightAnchor.constraint(equalToConstant: 18),
airPlayPickerView.centerXAnchor.constraint(equalTo: airPlayContainerView.centerXAnchor),
airPlayPickerView.centerYAnchor.constraint(equalTo: airPlayContainerView.centerYAnchor),
airPlayContainerView.leadingAnchor.constraint(equalTo: devicePopUpButton.trailingAnchor, constant: 6),
airPlayContainerView.centerYAnchor.constraint(equalTo: devicePopUpButton.centerYAnchor),
airPlayContainerView.widthAnchor.constraint(equalToConstant: 30),
airPlayContainerView.heightAnchor.constraint(equalToConstant: 30)
])
}

I don't believe Apple provides a way to programmatically enumerate AirPlay devices and select one via device ID. This used to be possible in macOS but they removed that capability. I think iOS is the same way unfortunately. |

Ok, I am trying to play Apple Music, but I can’t seem to be able to switch the output so that apple can use the output and then switch back to SFB when I’m playing local songs.
Any ideas?
Thanks!

Hi, we’re just about rapping up the dev cycle, and we’re trying to submit to Apple, but we are getting validation errors that seem to be aiming at SFB.
Any Ideas?
Thanks!

What errors are you getting that make you suspect SFBAudioEngine? |

Let me ask my partner, because from what he told me, I understood that these screenshots showed that SFB was the issue, but I’m looking at that and all I see is i386 issues. Looks like something in the settings is allowing 32bit instead of 64bit, or read/write permission which are in the plist.
I’ll let you know if we still need help. Thanks for the quick response. Once we release, can I send you a code so that you can enjoy the app for life for FREE? It’s the least we can do for you!
Thanks!

Hi, I’m getting a crash if MediaCenter or another music player that hogs the audio device is active when our app starts.
This is our code: // MARK: - Load Audio Device Hardware
@objc func loadAudioDeviceHardware() {
airPlayPickerView.delegate = self
// Observe when audio devices change
try? AudioSystemObject.instance.whenSelectorChanges(.devices) { _ in
DispatchQueue.main.async {
self.updateDeviceMenu()
}
}
print("Audio system object selector changes observer set up.")
// Retrieve the saved device UID and set the output device
if let uid = UserDefaults.standard.object(forKey: "deviceUID") as? String {
do {
// Fetch the audio device using the UID
if let deviceID = try AudioSystemObject.instance.deviceID(forUID: uid) {
// Check if the device is hogged by another application
try checkAudioDeviceStatus()
// Set the device if it's available
try? sfbAudioDevice.setOutputDeviceID(deviceID)
print("Audio device selected with UID:", uid)
}
} catch {
print("Error loading or checking the device:", error)
}
}
updateDeviceMenu()
}
// MARK: - Check Audio Device Status (if hogged)
func checkAudioDeviceStatus() throws {
// Safely retrieve the default output device
guard let currentDevice = try? AudioDevice.defaultOutputDevice else {
// If the device is unavailable, show an alert or handle it accordingly
let alert = NSAlert()
alert.messageText = "Audio Device Not Found"
alert.informativeText = "Unable to access the default audio device. Please ensure your device is connected properly."
alert.addButton(withTitle: "OK")
alert.runModal()
return
}
// If the device was found, check if it is hogged
do {
if try currentDevice.isHogged {
// Device is hogged, show an alert to the user
let alert = NSAlert()
alert.messageText = "Audio Device In Use"
alert.informativeText = "Audio Device is currently used by another application. Please release the audio device and try again."
alert.addButton(withTitle: "OK")
alert.runModal()
} else {
print("Audio device is available for use.")
}
} catch {
// Handle any errors that may occur while checking the hog status
let alert = NSAlert()
alert.messageText = "Error Checking Device Status"
alert.informativeText = "An error occurred while checking the audio device's status. Please try again."
alert.addButton(withTitle: "OK")
alert.runModal()
}
}
Thread 1: Precondition failed
func makeAudioDevice(_ objectID: AudioObjectID) throws -> AudioDevice {
precondition(objectID != kAudioObjectUnknown)
precondition(objectID != kAudioObjectSystemObject)
let objectClass = try AudioObjectClass(objectID)
switch objectClass {
case kAudioDeviceClassID: return AudioDevice(objectID)
case kAudioAggregateDeviceClassID: return AudioAggregateDevice(objectID)
case kAudioEndPointDeviceClassID: return AudioEndpointDevice(objectID)
case kAudioEndPointClassID: return AudioEndpoint(objectID)
case kAudioSubDeviceClassID: return AudioSubdevice(objectID)
default:
os_log(.debug, log: audioObjectLog, "Unknown audio device class '%{public}@' for audio object 0x%{public}@", objectClass.fourCC, objectID.hexString)
return AudioDevice(objectID)
}
}
Thanks!
Dorian

Is there an EQ method or a plan to implement?
