Audio

The Textual audio functionality allows you to process audio files in different ways. With this module you can:

• Generate a transcript

• Synthesize or redact sensitive values in the transcript

• Generate a redacted (beeped-out) audio file from the original recording

Before you can use these functions, read the Getting started guide and create an API key.

Textual audio processing supports the following audio file types: m4a, mp3, webm, mpga, wav

For file types such as m4a, make sure that your build of ffmpeg has the necessary libraries.

If you use Textual Cloud, or you self-host using the Azure AI Whisper integration, then file sizes are limited to 25MB or smaller.

If you self-host using Textual’s Automatic Speech Recognition (ASR) containers, then there are no limitations on file size.
