NVIDIA-Omniverse/kit-osc/README.md | # OSC Omniverse Kit Extension [omni.osc]
Omniverse Kit extension for sending and receiving OSC (Open Sound Control) messages.
*The OSC control surface app running on the iPad is [TouchOSC](https://hexler.net/touchosc).*
# Getting Started
Open the Community tab under Extensions window (`Window > Extensions`), search for `OSC`, and install and enable the `omni.osc` extension.
## Running the server
After installing and enabling the extension, you should see the following window.
Enter the private IP address of the computer running your Kit application and the desired port, then click `Start`. If you are prompted to configure your Windows Firewall, ensure that the Kit application is allowed to communicate with other devices on the private network.
You can find the private IP address of your computer by running `ipconfig` in the Windows terminal.
If you run the server on `localhost`, that means the server can only receive messages from OSC clients running on the same machine. If you want to receive messages from OSC clients running on other devices on the same network, you must run the server on an IP address that is visible to those devices.
Once the server is running, confirm that it can successfully receive messages by inspecting the verbose console logs. It might be helpful to filter only the logs that originate from `omni.osc`.
## Receiving messages with Python
Below is a python snippet that demonstrates how to handle OSC messages received by the server. It assumes that the OSC server configured above is running. You can paste and run the below snippet directly into the Omniverse Script Editor for testing.
```python
import carb
import carb.events
import omni.osc
def on_event(event: carb.events.IEvent) -> None:
addr, args = omni.osc.osc_message_from_carb_event(event)
carb.log_info(f"Received OSC message: [{addr}, {args}]")
sub = omni.osc.subscribe_to_osc_event_stream(on_event)
```
## Receiving messages with ActionGraph
Search for `OSC` in the Action Graph nodes list and add the `On OSC Message` node to your graph. The node takes a single input,
the OSC address path that this node will handle. This input can be a valid regular expression. Note that this input field does *not* support
OSC pattern matching expressions. The node outputs an OmniGraph bundle with two attributes named `address` and `arguments` which you
can access by using the `Extract Attribute` node.
You can find example USD stages that demonstrate how to configure an ActionGraph using this extension at [exts/omni.osc/data/examples](/exts/omni.osc/data/examples).
## Sending messages from Python
Since `omni.osc` depends on [python-osc](https://pypi.org/project/python-osc/), you can import this module directly in
your own Python code to send OSC messages. Please see the [documentation](https://python-osc.readthedocs.io/en/latest/) for additional
information and support.
```python
import random
import time
from pythonosc import udp_client
client = udp_client.SimpleUDPClient("127.0.0.1", 3334)
client.send_message("/scale", [random.random(), random.random(), random.random()])
```
You can paste and run the above snippet directly into the Omniverse Script Editor for testing.
## Sending messages from ActionGraph
This is not currently implemented.
## Limitations & Known Issues
- OSC Bundles are currently not supported.
- The OmniGraph `On OSC Message` node can only handle OSC messages containing lists of floating-point arguments.
# Help
The below sections should help you diagnose any potential issues you may encounter while working with `omni.osc` extension.
## Unable to receive messages
1. First, enable verbose logs in the console (filter by the `omni.osc` extension). The server will log any messages received.
2. Confirm that the computer running the Kit application and the device sending the OSC messages are on the same network.
3. Confirm that kit.exe is allowed to communicate with the private network through the Windows Defender Firewall. Note that
you may have multiple instances of kit.exe on this list. When in doubt, ensure that all of them have the appropriate permission.
4. Confirm that the Windows Defender Firewall allows incoming UDP traffic to the port in use.
5. Confirm that the device sending the OSC messages is sending the messages via UDP to the correct IP address and port.
6. Use a tool such as [wireshark](https://www.wireshark.org/) to confirm that the computer running the Kit application is receiving UDP traffic from the device.
## Unable to send messages
1. Confirm that the computer running the Kit application and the device receiving the OSC messages are on the same network.
2. Confirm that kit.exe is allowed to communicate with the private network through the Windows Defender Firewall.
3. Confirm that the device receiving the OSC messages is able to receive incoming UDP traffic at the port in use.

ilanhuang/audio2face-streamgpt-public/README.md | # Stream-GPT
Stream-GPT is an Omniverse Extension that uses OpenAI's GPT-3 model to create a virtual assistant. It allows users to interact with the assistant through both text and voice, and the assistant responds in kind. The extension uses OpenAI's Whisper ASR system to transcribe audio input and Eleven Labs' API to convert the assistant's text responses into audio.
## Getting Started
### Prerequisites
- Python 3.6 or higher
- Omniverse Kit
- Omniverse Audio2Face
- OpenAI API key
- Eleven Labs API key
### Installation
1. Clone the repository:
```bash
git clone https://github.com/ilanhuang/audio2face-stream-chatgpt.git
```
2. Install the required Python packages:
```bash
pip install -r requirements.txt
```
3. Update the `sys.path.append` in `extension.py` with the correct path to the `streaming_server` directory in your local clone of the repository.
```python
sys.path.append("C:\\Users\\YourUsername\\path\\to\\stream-gpt\\pkg\\audio2face-2022.2.1\\exts\\omni.audio2face.player\omni\\audio2face\\player\\scripts\\streaming_server")
```
4. Add the custom extension to Omniverse:
- Go to the "Windows" tab on the top of the screen.
- Scroll down to "Extensions".
- Click on the gear icon to open the Extensions settings.
- Click on the "+" button to add a new path to the custom extension.
- A window will pop up when you turn on the extension.
5. Set your OpenAI and Eleven Labs API keys, as well as the voice_id, model_id, and the Audio2Face's audioplayer's prim path (instance_name) in the extension's settings:
- Open the extension and click on the "Settings" button.
- Enter your OpenAI API key, Eleven Labs API key, voice_id, model_id and instance name in the corresponding fields. (A text file in the repository lists the available voice ids.)
## Usage
Once the application is running, you can interact with the virtual assistant through the UI. You can type your prompts into the text field and click on the "Send" button or use the "Record Audio" button to speak your prompts. The assistant will respond in the chat log and through your speakers.
You can also add a system to the GPT virtual assistant by typing it in the "System" field in the UI.
All interactions made with the extension are saved in a folder named "chat_logs" for future reference. | 2,294 | Markdown | 40.727272 | 358 | 0.762424 |

## [1.0.2] - 2023-07-06
- Upgraded the UI to allow users to add API keys, Voice_ID, Voice_Models, and Instance Name directly from the UI, eliminating the need for hardcoding.
## [1.0.0] - 2023-04-13
- Initial version of extension UI template with a window.

ilanhuang/audio2face-streamgpt-public/exts/stream.gptchat/docs/README.md | # Stream-GPT
Stream-GPT is an Omniverse Extension that uses OpenAI's GPT-3 model to create a virtual assistant. It allows users to interact with the assistant through both text and voice, and the assistant responds in kind. The extension uses OpenAI's Whisper ASR system to transcribe audio input and Eleven Labs' API to convert the assistant's text responses into audio.
## Getting Started
### Prerequisites
- OpenAI API key
- Eleven Labs API key
### SET UP
1. Set your OpenAI and Eleven Labs API keys, as well as the voice_id, model_id, and the Audio2Face's audioplayer's prim path (instance_name) in the extension's settings:
- Open the extension and click on the "Settings" button.
- Enter your OpenAI API key, Eleven Labs API key, voice_id, model_id and instance name in the corresponding fields. (A text file in the repository lists the available voice ids.)
## Usage
Once the application is running, you can interact with the virtual assistant through the UI. You can type your prompts into the text field and click on the "Send" button or use the "Record Audio" button to speak your prompts. The assistant will respond in the chat log and through your speakers.
You can also add a system to the GPT virtual assistant by typing it in the "System" field in the UI.
All interactions made with the extension are saved in a folder named "chat_logs" for future reference.
