Add Sound Annotation

Sound annotations in PDFs enable you to add audio content such as voice notes, music, or sound effects to your documents. Using PdfContentEditor, you can define a small clickable rectangle on a page that plays a specified audio file when activated.

1. Create a PdfContentEditor instance.
2. Bind the input PDF document.
3. Define a rectangle for the sound annotation.
4. Specifie the audio file, annotation name, page number, and sampling rate.
5. Save the updated PDF document.

def add_sound_annotation(infile, sound_file, outfile):
    # Create PdfContentEditor object
    content_editor = pdf_facades.PdfContentEditor()
    # Bind document to PdfContentEditor
    content_editor.bind_pdf(infile)
    # Add sound annotation to page 1
    content_editor.create_sound(
        apd.Rectangle(80, 450, 30, 30), sound_file, "Speaker", 1, "8000"
    )
    # Save updated document
    content_editor.save(outfile)
