Advanced Export Scenarios

​
Scenario: Long-Form Content (Split Audio)

Challenge: Content exceeds 5,000 character limit Solution: Generate segments and merge
1

Split Content Intelligently

Divide at natural breakpoints:
Chapter_3_Part_1.txt (4,500 chars) - ends at paragraph break
Chapter_3_Part_2.txt (4,500 chars) - slight overlap for continuity
Chapter_3_Part_3.txt (3,200 chars) - final segment
2

Generate All Segments

Use identical settings for consistency:
  1. Set voice configuration once
  2. Generate Part 1
  3. Rename: Chapter_3_Part_1
  4. Generate Part 2 (settings persist)
  5. Rename: Chapter_3_Part_2
  6. Continue for all segments
3

Export All as WAV

Important: Use WAV for editing:
  1. Click WAV on each segment
  2. Download all parts
  3. WAV format allows seamless merging
4

Merge in Audio Editor

Using Audacity (free):
  1. File > Import > Audio - load Part 1
  2. File > Import > Audio - load Part 2 (appends)
  3. Import remaining parts
  4. Add 0.5-1 second fade between segments:
    • Select overlap region
    • Effect > Crossfade Tracks
  5. Effect > Normalize - even volume across all segments
  6. File > Export > Export as MP3 (or WAV)
5

Verify Final Audio

Listen through complete file:
  • Check transitions sound smooth
  • Verify no volume jumps
  • Confirm no missing content
  • Test in target playback device
Overlap Technique: Have 10-20 characters overlap between segments. When merging, crossfade the overlap for seamless transitions.

​
Scenario: Character Dialogue (Separate Voices)

Challenge: Story with multiple characters needing different voices Solution: Export each character separately, then mix
1

Define Voice Profiles

Plan distinct voices:
CharacterVoiceSpeedMoodNotes
NarratorNormalNormalNeutralAuthoritative
HeroHighFastEnthusiasticEnergetic
VillainNormalSlowTenseMenacing
Wise ElderNormalSlowSeriousThoughtful
2

Separate Dialogue

Split script by character:
01_Narrator_Opening.txt: "Once upon a time..."
02_Hero_Line1.txt: "I must save the kingdom!"
03_Villain_Line1.txt: "You'll never succeed..."
04_Narrator_Transition.txt: "And so the battle began..."
3

Generate Each Character

For each dialogue piece:
  1. Configure for that character
  2. Generate audio
  3. Rename with character name and sequence
  4. Export as WAV
Example names:
01_Narrator_Opening
02_Hero_Line1
03_Villain_Line1
