Frequently Asked Questions

Find Quick Answers

What input formats are supported?

The tool accepts MP3, WAV, and AAC audio files. It does not process video. Large files may require batching, and there is a per-file size limit that varies by plan.

How accurate are transcripts?

Transcripts rely on automated speech recognition. Accuracy varies with audio quality, language, and accents. Users can specify language, enable timestamps and speaker labels, and post-edit results for final export.

Can I process multiple files at once?

Yes, batch mode supports queuing multiple audio files and exporting a set of PDFs in a single run. Each input yields an independent, properly formatted PDF with its own timestamps and optional speaker labels.

Can I edit transcripts before export?

Yes, transcripts can be reviewed, corrected, and timestamped as needed before final PDF export; you can adjust segments and labels to improve accuracy and readability.
