Explore PDF structure through natural HRTF spatial audio and private on-device document analysis. Spatial Audio PDF Reader helps people understand a PDF's layout by turning page position into 3D sound. When you hover over a title, heading, paragraph, caption, or image, the extension reads it aloud from the same direction it appears on the page. Content near the top sounds in front, content in the middle sounds to the left or right, and content near the bottom can sound slightly behind you. The extension uses HRTF audio processing to create clearer front, side, height, and rear direction cues through normal headphones or earbuds. This can help blind and low-vision users build a mental map of a document instead of hearing every item in one straight line. Features include: - Natural English voices with no paid API key - Read on hover with speech preloading for faster playback - Detection for titles, headings, paragraphs, captions, and images - A nine-position audio test - Safe switching between multiple PDF files - Local processing for PDF text and page layout *PDF contents are processed on your device and are not sent to the developer. The first use of a natural voice or image description may download a model that Chrome can cache for later use. For the strongest directional effect, use headphones or AirPods for both ears.
