## 1. Newbie Guide

### What is audio AI and how is it different from video AI?

Audio AI is the tech behind synthetic voices that sound nearly human — from a sample of your voice, AI learns and produces a synthetic clone (voice clone). You write text -> AI reads it back (Text-to-Speech).

**Differences vs video AI:**
- Video AI (skill 24): produces video with face + voice -> talking head, social video
- Audio AI (this skill): produces voice only -> podcast, audiobook, voiceover, narration

### When to use audio AI instead of video?

| Situation | Pick audio AI | Pick video AI |
|-----------|---------------|---------------|
| Long-form content (>10 min) | YES — podcast format | NO — too long for video |
| Don't want to be on camera | YES | NO |
| Need volume content fast | YES — 1 podcast = 10 shorts | YES but more expensive |
| Audience listens while driving / at gym | YES | NO |
| Need visuals to demo | NO | YES |
| Personal brand thought leader | YES — podcast = authority | YES — if face brand exists |

### 5 common mistakes

1. **AI voice sounds robotic:** sample too short or monotonic. Fix: re-record 3-5 minutes with varied emotions (happy, serious, sad).
2. **Mispronounced names/jargon:** TTS engines mishandle proper nouns. Fix: use phonetic spelling (e.g., "Anthropic" -> "an-THROW-pic") in the script.
3. **Audio clipping:** levels too hot. Fix: target -3dB peak, -16 LUFS loudness.
4. **Background noise/echo:** untreated room. Fix: small room with curtains and rugs, or apply NVIDIA Broadcast / Krisp / Adobe Enhance Speech.
5. **Boring podcast:** no editing, too many "ums". Fix: Descript auto-removes filler words, add light background music (-25dB).
