# RAG over audio files using AssemblyAI
This project builds a RAG app over audio files.
We use:
- AssemblyAI to generate transcripts from audio files.
- LlamaIndex for orchestrating the RAG app.
- Qdrant VectorDB for storing the embeddings.
- Streamlit to build the UI.
A demo is shown below:

## Installation and setup
**Setup AssemblyAI**:
Get an API key from [AssemblyAI](http://bit.ly/4bGBdux) and set it in the `.env` file as follows:
```bash
ASSEMBLYAI_API_KEY=<YOUR_API_KEY>
```
**Setup SambaNova**:
Get an API key from [SambaNova](https://sambanova.ai/) and set it in the `.env` file as follows:
```bash
SAMBANOVA_API_KEY=<YOUR_SAMBANOVA_API_KEY>
```
Note: Instead of SambaNova, you can also use Ollama.
**Setup Qdrant VectorDB**
```bash
docker run -p 6333:6333 -p 6334:6334 \
-v $(pwd)/qdrant_storage:/qdrant/storage:z \
qdrant/qdrant
```
**Install Dependencies**:
Ensure you have Python 3.11 or later installed.
```bash
pip install streamlit assemblyai llama-index-vector-stores-qdrant llama-index-llms-sambanovasystems sseclient-py
```
**Run the app**:
Run the app by running the following command:
```bash
