BUG: Waveform animation runs continuously even when mic is disabled, causing unnecessary CPU usage

What happened?

📌 Issue Overview

The waveform animation continues running even when the microphone is disabled or not listening. The animation controller is started with _waveformController.repeat() but is never stopped, leading to unnecessary CPU/GPU usage.

🔍 Steps to Reproduce

1. Open the chat screen where the waveform animation is displayed
2. Enable the microphone / start listening
3. Disable the microphone or stop listening
4. Observe that the waveform animation continues running

🎯 Expected Behavior

The waveform animation should stop when the microphone is disabled or listening ends, and only run while the mic is active.

🚨 Actual Behavior

The waveform animation keeps running continuously even when the microphone is not listening, consuming unnecessary CPU/GPU resources.

If you look closely that initially when I was not speaking it was showing the waveform. Also I think that the waveform should be more vivid for better user experience

💡 Suggested Improvements

• Stop the animation controller when the microphone is disabled or listening stops:

  _waveformController.stop();

• Start the animation conditionally based on the microphone/listening state instead of calling repeat() unconditionally.

I’d like to work on this issue and briefly outline how I plan to address it.

I’ll identify where the waveform animation controller is started and ensure it is tied to the microphone/listening state instead of running unconditionally. The animation will start only when the mic is actively listening and will be stopped explicitly when listening ends or the microphone is disabled, to avoid unnecessary CPU/GPU usage.

I’ll also review the waveform parameters to make the animation more responsive while the mic is active, without impacting existing chat or voice logic.

If this approach looks good, could you please assign this issue to me?

Thanks!
