💡 AI App Starter Prompt

Use this prompt to build a project with audiostretchy-f32 
Develop a Python-based audio processing mini-app called 'TempoTweak' that leverages the 'audiostretchy-f32' package to perform high-quality time-stretching on audio files. The app should allow users to input an audio file and specify a tempo adjustment factor (either increasing or decreasing the speed without altering the pitch). Additionally, the app should provide a preview of the modified audio before saving it to disk.

Key Features:
1. User Interface: Implement a simple command-line interface (CLI) that guides users through the process of selecting an input audio file, specifying the tempo adjustment factor, and choosing where to save the output file.
2. Tempo Adjustment: Use 'audiostretchy-f32' to stretch or compress the input audio based on the user-specified tempo adjustment factor.
3. Preview Functionality: After processing the audio, play a short preview clip of the modified audio to ensure satisfaction before finalizing the save operation.
4. Error Handling: Ensure robust error handling for cases such as invalid file formats, unsupported operations, or missing files.
5. Documentation: Provide clear documentation on how to install dependencies, run the app, and troubleshoot common issues.

How to Utilize 'audiostretchy-f32':
- Import the necessary modules from 'audiostretchy-f32'.
- Load the input audio file using the library's capabilities.
- Apply the specified tempo adjustment factor to the loaded audio data.
- Save the processed audio data to a new file while maintaining high quality.
- Optionally, use additional functionalities provided by 'audiostretchy-f32' to enhance the audio processing experience.
