Upload your audio recordings to an episode to start editing. Henshu processes uploaded files automatically after upload.

​
How do I upload audio?

  1. Open an episode in the editor
  2. Either drag and drop audio files into the editor, or click the Upload button and select files from your computer
  3. Your files begin uploading, and you’ll see a progress indicator
  4. Once uploaded, the audio file card shows Processing…
  5. When processing finishes, the file is ready to edit
You can upload multiple files at once. Large files are automatically handled with multipart upload.

​
What happens after upload?

After you upload a file, you’ll see a series of status indicators on the audio file card:
  1. Processing… converts the file to a standard audio format for consistent editing. You need to wait for this to finish before editing.
  2. Enhancing… runs the AI enhancement pipeline (noise reduction, mouth noise removal, tone optimization, volume leveling). You can start editing while this runs.
  3. Transcribing… generates a transcript of the audio. You can start editing while this runs.
Enhancement and transcription happen in the background. You don’t need to wait for them to finish before arranging blocks, making cuts, or doing other edits.

​
Supported formats

Henshu accepts common audio formats including WAV, MP3, M4A, AAC, FLAC, OGG, and AIFF. Files are converted to a standard format during processing, so the original format doesn’t affect editing quality.

​
