In short

With the AAC audio file the engine writes the written notes: the transcript first, then the sections Thesis, Key ideas, Definitions. The speech is in Russian, the free plan gives 3 files a day, and one file is up to 30 minutes.

How it works

How to get the file and turn it into structured notes

  1. 1

    Check the codec of the file

    AAC is MPEG-4 part3 and stands in the list of the audio formats of the VLC player next to MP3

  2. 2

    Upload the file

    The engine takes the AAC audio file from the widget of the page; the speech is in Russian, and the written notes comes back with the timecodes.

  3. 3

    Run the instruction of the written notes

    The transcript of the AAC audio file goes to the instruction that is written for the written notes, and the sections of the answer are Thesis, Key ideas, Definitions.

  4. 4

    Mark the language of the speech

    The speech of the AAC audio file is Russian, one of the 99+ languages the engine reads, and the widget is left on Russian while the written notes is written.

  5. 5

    Check the file before the upload

    In the table of the codecs and the containers of OBS Studio the AAC row names the MP4, MOV, MKV and TS containers

The result

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.

The facts

What AAC keeps, and what it says about it

Where the file is

The FFmpeg library of Audacity imports M4A (AAC), AC3 and WMA, a much larger range of audio formats than the program reads on its own.

What the file is

The VLC player reads AAC among the audio formats it plays: AAC is MPEG-4 part3 and stands next to MP3 in the list.

What can go wrong

The Telegram Bot API takes an audio file in the .MP3 or .M4A format, and the M4A carries the AAC codec.

What the platform says

In the table of the codecs and the containers of OBS Studio the AAC row names the MP4, MOV, MKV and TS containers.

What the platform says

The case

What the recording does not give you

The file of the AAC audio file is what the AAC keeps. The VLC player reads AAC among the audio formats it plays: AAC is MPEG-4 part3 and stands next to MP3 in the list. The engine reads the Russian speech, and the sections Thesis, Key ideas, Definitions come out of it.

Tips

  • Read the sections of the written notes before you send it on.

  • The engine does not translate the AAC audio file from Russian.

  • Rename the file of the AAC audio file before you send it.

  • Bots can currently send audio files of up to 50 MB in size, and the limit may be changed in the future.

  • Because of software patents Audacity cannot include the FFmpeg software: the free FFmpeg library of a third party is installed separately.
