PDF-to-Audio

Convert PDF files to broadcast-quality audio via OCR + neural TTS. Runs fully offline — no cloud APIs, no data sent anywhere.

How it works

1. PDF extraction — text layer read directly with PyMuPDF (milliseconds); Tesseract OCR fallback for scanned/image-only pages
2. TTS synthesis — two modes selectable per conversion:
   • Fast — Meta MMS-TTS (facebook/mms-tts-eng, VITS, 16 kHz) — ~10× real-time on CPU
   • Quality — Coqui Tacotron2-DDC (LJSpeech, 22 kHz) — richer prosody
3. Audio processing — pedalboard DSP chain (HPF, presence EQ, de-esser, compressor) applied to all output regardless of mode
4. Export — MP3 (192 kbps) or WAV (16-bit PCM)

Both models are pre-baked into the image — no downloads at runtime.
