Oh hey! I've been stuck trying to figure out how to have my
AVAudioPlayerNode() automatically stop playback when it reaches the end of the file in my SwiftUI project. As you can see below, my audio files that don't go through the
AVAudioEngine but rather the
AVAudioPlayer have an
audioPlayerDidFinishPlaying function and that works great. However for the audio files that go through the engine using the
play function don't have anything like this, and I can't figure out how to get it to behave similarly.
I've tried building something like...

Instead of using
avPlayer.scheduleFile(file, at: nil), use the form of the method with a completion handler:
I have an app who's foundation is essentially based on https://blckbirds.com/post/voice-recorder-app-in-swiftui-1/.
It's Swift / XCode 12.5.1 and works great. I call the audio using
self.audioPlayer.startPlayback(audio: self.audioURL) which plays the recording perfectly.
Now I want to add the ability for the user to adjust the pitch and speed of the recorded audio. It doesn't have to save the changes, just apply the changes while playing the file on the fly.
I found https://www.hackingwithswift.com/example-code/media/how-to-control-the-pitch-and-speed-of-audio-using-avaudioengine which simplifies the process of applying pitch changes. I'm able to change the
startPlayback above to

Turns out this was simpler than I had thought using
@AppStorage and conditionals to integrate the desired player. Thanks!
I am trying to make an audio player in SwiftUI, Audio player should have these functionality.
- Play/Stop Audio
- Play in loop
- Change volume through slider
- Change audio pitch through slider.
There are two problem currently I am facing
- audio player is not using volume and pitch slider value
- While I stop and play and change volume/pitch slider app crashes with following message.

Your first problem is that you're not tracking changes of volume/pitch values. To do so move them to a class:
ive got a Vue component which lets me zoom in on an image, using the mouse wheel works fine, however pinch zoom behaves strangely.
Basically if you put 2 fingers on the screen far apart it zooms in a lot, put them in closer together and it zooms in a bit. What should happen is it doesn't zoom in or out until you actually move your fingers in or out.

I'm not sure I understand your problem correctly but as I try I think the problem of your code is on this line:
I have got a Vue component where i can zoom in on an image and then move it around the container. When zoomed there is also a small viewport to show what part of the image is visible. However when moving the image around it is moving faster than the mouse, i'm guessing this is due to using the
I also feel like when i'm clicking and dragging on the viewport I shouldn't be reversing the values twice however this seems to be the only way to get it moving the square with the mouse....

A part of this problem is a result of calling
Math.floor all the time. Each time you call
Math.floor your next calculations will be less accurate.
If you still want to round numbers, do it only at the end of your calculations chain or even in the place where you are using the variable. For example:
I have a .mp3 file that contains just voice and I would like to adjust the speed (slower or faster) while maintaining the same clarity. No chipmunks! Then write out the modified file to disk. In order to do this, I am trying to use the AVAudioEngine Framework but am a complete N00B to the framework. All the examples, I have found, are geared to modifying music or recording voice then playing it audibly. I just want to convert to a different speed and have it spit out the modified file. This was all I could figure out so far, I documented my confusion in the comments of the code....

Here is proof-of-concept code that speeds up a stereo M4A file and saves it as a WAVE file. There is minimal error handling and no attempt at handling different channel layouts, but hopefully it should get you started:

You can use SpeedControl like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the SpeedControl component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
