Modification in the current code

[Parthhyperlink]

Hello , Thanks for your library. I want to use this as a progress bar and successfully integrate, now the issue is that when progress will fill with gradiant, i dont want that, so is that possible to remove this without making any change in the pod file?

Please find attachment, how i used as a progress bar.

Thank you.

Hello @Parthhyperlink and thank you for your message!

Good job on integrating it as a progress bar, as I can see in your screenshot 👌 It could be a good evolution of the library actually, having only the top part of it (instead of a "mirrored" two sided graph).

You should be able to not have any gradient by setting both gradientStartColor and gradientEndColor to the same color 👍 This wouldn't require any change on the Pod.

self.audioVisualizationView.gradientStartColor = UIColor.red
self.audioVisualizationView.gradientEndColor = UIColor.red

Let me know how it goes!

Hello, Thanks for your quick response. No, i can't set a start and end color both a red color, becuase when progress wasn't start at that moment i need to set a Grey color and after animation start it will be fill up with red color. but do not need a red color with gradient. also i used this view in the Uitableview cell, so once progress animation is start and i scroll a table view and cell is not visible than progress is stop and once i scroll down and cell is visible it starts again, but i want it continuously start even though cell is not visible. please help me in this because of this right now i am stuck here.

If you have any another suggestion or library for this type of Audio progress please suggest me.

Thank you.

Hello @Parthhyperlink, my apologies for the delay!

Color Challenge

So if I understand well:

• You need to have a plain grey color when the progress isn't started
• You need to have a plain red color when the progress is started

This should be achievable if you change the colors every time you start or pause/stop playing:

self.audioVisualizationView.audioVisualizationMode = .read
self.audioVisualizationView.meteringLevels = [0.1, 0.67, 0.13, 0.78, 0.31]

// Start playing
self.audioVisualizationView.play(for: 5.0)
self.audioVisualizationView.gradientStartColor = UIColor.red
self.audioVisualizationView.gradientEndColor = UIColor.red

// Stop playing
self.audioVisualizationView.stop()
self.audioVisualizationView.gradientStartColor = UIColor.gray
self.audioVisualizationView.gradientEndColor = UIColor.gray

Animation Stops Issue

That sounds like a UI issue, I am not sure what is happening exactly here and I would need to debug. I can try to give it a try in the coming days. My guess is that the view may stop drawing when the Table View scrolls?

I don't know of any other library that does exactly the same thing on the top of my head, but I would assume there are other ones you could use that would do what you need, which seems to be a pretty common use case. Keep me posted!

Hello Thanks for your response.

Is it possible to start an animation from any specific time?

For example : There is a 100 bars and animation time is 3 minutes, so i need to start animation from 50 number bar and time is 1 minute and 45 sec? is that possible?

Thank you.

Hello @Parthhyperlink,

This is not possible at the moment. For now, we can do the following:

self.audioVisualizationView.play(for: 5.0)
self.audioVisualizationView.pause()
self.audioVisualizationView.play(for: duration - 5.0)
self.audioVisualizationView.stop()

But we have to start from the beginning of the sample. We could consider adding a function that looks like this however:

let totalDuration: TimeInterval = 3.0 * 60.0 // 3 minutes
self.audioVisualizationView.play(from: 60.0 + 45.0, for totalDuration) // start at 1mn 45s 

Would that makes sense?

This would be a great functionality to have.

@bastienFalcou do you intent to add this functionality?
