Convert and transcribe new audio files in Amazon S3 with CloudConvert and Deepgram

This workflow runs when a new audio file is added to an Amazon S3 bucket. It uses CloudConvert to create signed URLs, which are then sent to Deepgram so the audio transcription can be done. The Deepgram action takes a callback URL where the transcription will be added to once it is completed. This workflow can handle very large audio files because the callback server allows for transcription to be done asynchronously, avoiding the Zapier 30 second timeout.
