Google AI Studio POC Starter

Index: AI Studio POCs Master Index

An AI-powered audio analysis tool that acts as your personal audio engineer. Upload a voice recording and receive customized EQ recommendations tailored to your unique vocal characteristics.

Overview

This React application leverages Google's Gemini AI to analyze voice recordings and generate personalized audio equalization settings. It provides a comprehensive vocal profile analysis and exports ready-to-use EQ presets for Audacity.

Features

  • Audio Recording/Upload: Record directly in-browser or upload existing audio files
  • AI-Powered Vocal Analysis: Uses Google Gemini to analyze vocal characteristics including:
    • Fundamental frequency range
    • Vocal timbre and tone
    • Key vocal characteristics
  • Personalized EQ Recommendations: Generates custom EQ settings optimized for your voice
  • Audacity Export: Automatically creates Audacity-compatible EQ curve XML files
  • Modern UI: Clean, responsive interface with real-time processing feedback

Technology Stack

  • Frontend: React 19.2.0 with TypeScript
  • Build Tool: Vite 6.2.0
  • AI Model: Google Gemini API (@google/genai)
  • Styling: Tailwind CSS (custom gradient themes)

Getting Started

Prerequisites

Installation

  1. Install dependencies:

    npm install

  2. Set up your API key:

    • Create a .env.local file in the root directory
    • Add your Gemini API key: 
      GEMINI_API_KEY=your_api_key_here

  3. Run the development server:

    npm run dev

  4. Open your browser to http://localhost:5173

How It Works

  1. Record or Upload: Use the built-in recorder or upload an audio file (WAV, MP3, etc.)
  2. AI Analysis: Gemini analyzes the audio to identify vocal characteristics
  3. Get Results: Receive a detailed vocal profile and custom EQ settings
  4. Export: Download the Audacity XML file to apply the EQ curve in your DAW

Use Cases

  • Content Creators: Optimize your voice for podcasts, YouTube videos, or streaming
  • Musicians: Get professional EQ recommendations for vocal recordings
  • Audio Engineers: Quick starting point for vocal EQ before fine-tuning
  • Learning Tool: Understand how different vocal characteristics map to EQ settings

Limitations

  • This is a proof of concept for demonstration purposes
  • EQ recommendations are AI-generated and may require manual adjustment
  • Best results with clear, isolated vocal recordings
  • Requires active internet connection for Gemini API calls

AI Studio POC

This project contains a proof of concept (POC) that was autopopulated by Google AI Studio. It is intended as a code starter and may not yet have been manually reviewed and/or taken further. I create some Gemini POCs, in particular, to experiment with/test the capabilities of multimodal AI.
