Developer uses Claude to build AI audio ad generator with Go backend and ElevenLabs integration
Project overview
A developer working in ad tech built Prompt Audio Ads to address production bottlenecks in audio advertising. The tool takes short text scripts and generates complete audio ads with AI voice and background music in approximately 30 seconds. It supports English and Arabic languages and is available to try at promptaudioads.com.
Technical implementation
The backend is built in Go with three main components:
- ElevenLabs API integration for AI voice generation
- ffmpeg audio processing pipeline for trimming and mixing
- Music genre preset system with 18 different presets
Claude helped debug and optimize the audio processing flow when the developer encountered issues with audio trimming and mixing voice tracks with background music.
Landing page optimization
Claude reviewed the landing page and identified several issues:
- Conflicting CTAs ("Join Waitlist" vs "Generate Your First Ad Free")
- A section headline that made the product sound slow
- Sample cards showing "Coming soon" that were hurting user trust
Claude rewrote the hero section and suggested alternative headlines until reaching a suitable version.
Development insights
The developer shared key learnings from working with Claude on this project:
- Claude performs best with clear constraints (e.g., "Write me a headline that sounds like the builder wrote it, not a marketer, and doesn't use the word 'powerful'")
- For code work, the most effective pattern was: developer builds first version, Claude helps debug and optimize
- Starting from Claude-generated code and modifying it was slower than the reverse approach
- Claude can't replace human taste - the developer rejected about 60% of suggestions as too salesy or not matching their voice
- The 40% of suggestions that worked saved weeks of development time
The project addresses a specific pain point in ad tech where agencies need audio ads for podcasts, Spotify, and radio but face traditional production hurdles like hiring voice actors, booking studio time, mixing, and waiting days for completion.
