Separate Dialogue, Music, and Sound Effects in ComfyUI

说明与用途

此工作流程使用 ComfyUI-DBS 将视频中的对白、音乐和音效分离，保留音乐和音效，同时将对白单独提取为音轨。

问题

A video arrives with a single mixed soundtrack; muting removes all audio, but the goal is to replace only the dialogue while preserving music and sound effects.

结果

The workflow successfully separates dialogue from music and SFX, allowing the user to replace or remove dialogue while keeping the original background audio intact.

工作流

• Load Video → Get Video Components (extract frames, frame rate, audio)
• DBS Loader → DBS Separate (split audio into music, SFX, speech)
• Merge Audio (set to add) to combine music and SFX
• Create Video → Save Video (write video with combined soundtrack)
• Save separate dialogue track as FLAC

证据

I built ComfyUI-DBS to bring that separation into a ComfyUI workflow. It splits a soundtrack into music, sound effects, and speech, then lets you save the parts or combine them again.

The workflow performs these steps: Load Video → Get Video Components, DBS Loader → DBS Separate, Merge Audio, Create Video → Save Video, and a separate audio output saves the dialogue as FLAC.

It runs locally on a CPU or NVIDIA CUDA GPU. The two available models total about 23 MB to download.

For dialogue removal, the workflow adds music + SFX and uses that as the video's new soundtrack.

The verification report records: Six CPU comparison cases: the pack's raw output matched the official package byte for byte.
