Is your feature request related to a problem? Please describe.

When using Bluetooth headphones or speakers on macOS, the audio visualizer appears slightly ahead of the sound being heard.

The visualizer reacts to beats, pauses, and transitions before the corresponding audio reaches the Bluetooth device. This does not appear to happen, or is much less noticeable, when using the MacBook’s built-in speakers.

Describe the solution you'd like

Would it be possible to account for Bluetooth output latency, or add a configurable visualizer delay such as:

audio_visualization_delay_ms = 150

A configurable offset could allow users to synchronize the visualizer with delayed Bluetooth or AirPlay audio output.
