ComfyUI-audio-speed is a specialized tool designed to address inconsistencies in audio sample rates within ComfyUI, specifically converting audio to a unified 48KHz frequency. It also provides a custom audio speed adjustment feature, allowing users to manipulate audio playback speeds to match different frame rates used in video rendering.
- Converts various audio sample rates to a standardized 48KHz, preventing errors during audio merging.
- Offers a customizable audio speed adjustment node, defaulting to 0.7x speed, which is useful for aligning audio with different frame rates.
- Enables real-time visualization of frame alignment metadata, enhancing the workflow for audio-visual projects.
Context
This tool serves as an extension for ComfyUI, focusing on resolving issues related to audio sample rates and playback speeds. By providing a unified audio frequency conversion and speed adjustment capabilities, it enhances the overall functionality of ComfyUI in multimedia projects.
Key Features & Benefits
One of the primary features is the conversion of varying audio sample rates to a consistent 48KHz, which is crucial for avoiding discrepancies when merging audio tracks. Additionally, the custom speed adjustment node allows for precise control over audio playback speeds, making it easier to synchronize audio with video frame rates, particularly in environments where standard frame rates differ.
Advanced Functionalities
The tool includes a unique capability for dynamically adjusting audio speed based on the frame rate of the video being processed. It provides a default setting that accelerates audio to match a 23FPS frame rate while working in a 16FPS environment, which can be adjusted as needed for other projects. Furthermore, it allows for real-time verification of audio and video alignment through its modular preview nodes.
Practical Benefits
By integrating this tool into their workflow, users can significantly improve their efficiency in handling audio for video projects. The ability to standardize audio sample rates and adjust playback speeds ensures higher quality outputs and reduces the likelihood of errors, ultimately leading to a smoother and more coherent audiovisual experience.
