• Category: Video Helper Suite 🎥🅥🅗🅢
• Output node: False

The VHS_LoadAudio node is designed for loading audio files into the Video Helper Suite environment. It supports a variety of audio formats and allows for seeking a specific start time within the audio file, making it a versatile tool for audio processing and manipulation within video projects.

Input types

Required

• audio_file
  • Specifies the path to the audio file to be loaded. The node supports a range of audio formats, making it flexible for use with various audio sources.
  • Comfy dtype: STRING
  • Python dtype: str

Optional

• seek_seconds
  • Determines the start time in seconds from which the audio should begin playing. This allows for precise control over the playback start time within the audio file.
  • Comfy dtype: FLOAT
  • Python dtype: float

Output types

• audio
  • Comfy dtype: VHS_AUDIO
  • The loaded audio data, ready for use within the Video Helper Suite for further processing or integration into video projects.
