VHS Audio To Audio
The Legacy VHS_AUDIO to Audio🎥🅥🅗🅢 node technically processes the input VHS_AUDIO data stream by invoking an FFmpeg subprocess.
The Legacy VHS_AUDIO to Audio node is a format conversion tool. Its core function is to convert deprecated VHS_AUDIO format data into the standard AUDIO format used within ComfyUI workflows. This node is primarily used to process audio data generated by older versions or specific external nodes, enabling it to be recognized and processed by other audio nodes in the current workflow.
Node Functionality
Technically, this node processes the input VHS_AUDIO data stream by calling an FFmpeg subprocess. It decodes the data into raw PCM data in 32-bit floating-point little-endian (f32le) format and then converts it into a tensor using PyTorch. The node automatically parses the audio sample rate and number of channels (supporting mono and stereo) from the FFmpeg output information. If parsing fails, it defaults to a sample rate of 44100 Hz and a stereo format. Finally, the audio data is reshaped into the standard tensor structure of (1, channels, samples).
Node Parameter Description - Legacy VHS_AUDIO to Audio🎥🅥🅗🅢
Inputs
| Parameter Name | Data Type | Required | Default Value | Range/Options | Description |
|---|---|---|---|---|---|
vhs_audio | VHS_AUDIO | Yes | - | - | Input parameter vhs_audio: Receives deprecated VHS_AUDIO format audio data as the source input for conversion. |
Outputs
| Parameter Name | Data Type | Description |
|---|---|---|
| audio | AUDIO | Output parameter audio: Outputs the converted standard AUDIO format data, containing the waveform and sample rate. |
Usage Scenarios
In practical applications, when your workflow contains an old node that generates VHS_AUDIO format (e.g., some unmaintained video processing nodes), and subsequent steps require standard audio nodes like Load Audio or Audio Combine, you must use this node as a bridge. Connecting it after the old node converts the audio stream into a universal format, allowing you to proceed with subsequent audio processing or video synthesis workflows.
Notes
Please note that the VHS_AUDIO format itself is marked as deprecated. This node serves only as a backward-compatible transitional solution. If the input data is invalid or the FFmpeg processing encounters an error, the node will throw an exception and interrupt the workflow.
