# 5 minute challenge: summarize audio
This guide will show you how to swiftly build from scratch a workflow that transcribes and summarizes audio recordings
1. Go to and click the **New flow** button and then choose **Start with blank**
2. There will already be **Start** end **End** nodes on the canvas. Place everything else between them.\
\
Go to the **Settings** of the **Start Node Form** and click **Configure fields** to start adding your data
3. Add one field, call it, for example, `audio`, and change the input type to `String/URI` to make it suitable for storing files. Click **Save**
4. You can upload the audio file from your computer or, alternatively, use the **Set url** button if you have a link to the file. \
\
We'll use Carl Sagan's "The pale blue dot" speech as an example file. Here's the link:
5. Hit the **Execute** button and then click **Save and execute** to run this node and generate the output. We need it to move further.
6. Use the search panel on the left to find a processor that transcribes audio. If you already know the name of your desired processor, type it. Alternatively, you can type what you want to do — like `audio to text` there and pick by the name and description.\
\
**whisperx-a40-large** looks promising, drag it to the canvas
7. Connect the `audio` output of the **Start** node with the input of the **whisperx** node and click the **Execute** button on the latter. It will take a while to transcribe an audio file
8. Drag the **ChatGPT** processor to your canvas, connect the output of the **whisperx** with the **ChatGPT's** input and go to the settings of the latter. Review the instructions in paragraphs 6-8 if needed. You can move your nodes around whatever you like to create a convinient workspace
Locate the **Messages** section in the settings and click the pencil to add instructions for the **ChatGPT**
9. Click **Add message**. \
\
Change the type of the message to `System` as recommended by OpenAI to emphasize that it's a high-level instruction and to guide the model's behaviour
The prompt here is rather straightforward: `summarize a following audio transcript`
10. Add another message and click the **#** symbol. The **Expression editor** will open. In case of the **ChatGPT** node we need it to get data from other nodes
There is a list of the nodes on the left. Click on the **whisprex-a40-large** to see its output data. Keep going until you end up with `segments` — that's where the transcription is stored.\
\
Drag the `segments` to the expression field
The result should look similar to this. Don't forget to click the **Save** buttons in the **Expression editor** and before closing the node settings.
Click the **Execute** button on the **ChatGPT** node after you set everything
11. In principle, you are good to go now: the **ChatGPT** node generates summary, and you can copy and use it. But let's do some housekeeping to make sure that this workflow will be reusable and suitable to API integrations.\
\
Open settings of the **End Node Form**
Add a field and name it, there's no need to change the field type now
Connect the `success` output of the **ChatGPT** node with the newly generated input of the **End** node and execute the **End** node
12. Now you have your result in the **End** node. Why it's important? We'll cover this later\
\
If you hover the text you'll see the button to copy and take it elsewhere
13. Once you have the workflow built, there's no need to run nodes one by one anymore. Simply change the file in the **Start** node and use the **Play** button on the top panel to launch the entire workflow.
14. And one last thing. It's a good idea to give your workflow a comprehensive name.\
\
Locate the **cog** in the top bar, fill in the suitable **Flow name** and click **Submit**
