Upload Audio Input in AgenticFlow AI

What is an Upload Audio Input?

An Upload Audio Input is an input component that allows you to upload an audio file to the cloud and access it via a temporary URL. This URL can be used in other workflow actions, such as transcribing the audio or summarizing the content of a sales call. For security reasons, AgenticFlow AI does not store your file permanently; the provided URL expires within 3 days after upload. Therefore, it is recommended to apply the desired analysis steps right after the upload.

When to Use the Upload Audio Input Component

The Upload Audio Input component is suitable for scenarios where you need to process an audio file. For example, you can upload a recording of a sales call and run it through an LLM to transcribe and summarize the key points discussed during the call.
