How to get the file and turn it into a task list
- 1
Check the header
A file with a standard header is imported as an ordinary audio file; a raw PCM file is imported with File > Import > Raw Data
- 2
Give the file to the service
The file of the PCM audio file is attached in the widget of this page, and the speech is marked as English; the answer comes back as the task list.
- 3
Apply the instruction of the task
The instruction that is set for this task goes through the transcript of the PCM audio file and writes the task list in the sections Topic, Tasks, Ideas for later; nothing is added that was not said.
- 4
Set the language of the speech
The speech of the PCM audio file is English, one of the 99+ languages the engine reads, and the widget is left on English while the task list is written.
- 5
Check the file before the upload
In the table of the codecs and the containers of OBS Studio the PCM row names the MP4, MOV and MKV containers
What comes back from the engine
- TXT
One segment per line, the way a person wrote it down. It is the format to paste into a ticket, a chat or a document.
- TXT, CSV
The start and the end time of every segment, and the speakers named separately when you ask for it.
- SRT, VTT
SRT and VTT with the time of every line, so the recording can carry its own subtitles.
- Markdown, DOCX
The transcript is edited through the API and exported as Markdown for a wiki, or as DOCX for a review.

Questions about PCM audio file and a task list
What does the PCM say about the PCM audio file?

Who reads the task list after the PCM audio file is sent?
the person who made the memo. The transcript of the PCM audio file is read first, and the task list comes out of it in the sections Topic, Tasks, Ideas for later.
What do I get without a card?
3 files a day of up to 30 minutes every day, and the export of the text in the formats of the service, so the task list comes back in every one of them.
Do I need an account for the PCM audio file?
The file of the PCM audio file and the widget are enough: the engine reads the English speech and writes the task list.
