Waveform Split Channels

By default, stereo and multi-channel audio is downmixed to mono before the waveform is rendered. Setting video-wave-split=true disables the mono downmix and instead renders each audio channel as a separate waveform stacked vertically within the bounding box.

This enables per-channel color assignment via video-wave-color using pipe-separated values (e.g., video-wave-color=FF6B9D|00E5FF for pink left and cyan right channels).

video-wave-split accepts the following values:

• false — downmix all channels to mono (default).
• true — render each channel as a separate waveform.
