Show HN: My Journey to Integrating Stability AI’s Compact Audio Model into an iOS App

Unlocking Audio Creativity with Diffuzion: My Journey with AI Models

I’m thrilled to share my experience developing Diffuzion, an iOS app leveraging Stability AI’s stable-audio-open-small model. Navigating the complexities of model formats and conversion tools was a challenge, but I embraced it wholeheartedly.

Key Highlights:

  • Technical Challenges: Encountered limitations with TensorFlow Lite’s GPU support, forcing a switch to CPU-based solutions using XNNPack.
  • Performance Boost: Using Apple’s CoreML tools for the autoencoder model drastically improved performance, especially on older devices.
  • Unique Outputs: While some audio quality may vary, unexpected results foster creativity.
  • User-Friendly Features: Easily share audio clips as ringtones in iOS 26; premium exporting available with a special promo code: DIFFUZION4HN (valid until Nov 14).

I welcome your ideas for enhancing Diffuzion! Join the conversation and let’s shape the future of audio creation together. Please share or reach out!
