Usage

Basic Usage

  1. Add the Split Audio node to your workflow.
  2. Connect it to a node that provides an audio file (e.g., HTTP Request, Read Binary Files).
  3. Configure the chunk size and other parameters.
  4. The node will output multiple items, each containing a chunk of the original audio file.

Example with Binary Files

  1. Add a Read/Write Files from Disk node to read an audio file.
  2. Connect the Split Audio node after it.
  3. Set the Input Type to "Binary Data".
  4. Configure the chunk size (e.g., 10 MB).
  5. Run the workflow to split the audio file.

You can also use any node that provides binary data as output, such as the Google Drive node or the HTTP Request node.

Example with File Path

  1. Add a Read/Write Files from Disk node to get the file path.
  2. Connect the Split Audio node after it.
  3. Set the Input Type to "File Path".
  4. Set the File Path Field to the expression {{ $json.directory }}/{{ $json.fileName }}.
  5. Configure the chunk size and other options.
  6. Run the workflow to split the audio file.

Example Workflow

A typical workflow using the Split Audio node might look like:

  1. Trigger Node → 2. Read Audio File → 3. Split Audio Node → 4. Process Individual Chunks
