AUDIO FILES

Turn audio or a video soundtrack into text

Import a supported audio or video file into the recording library. Video import keeps its audio track only. Set the spoken language and run AI recognition. The transcript can then be saved as a note, searched and summarised. Recognition of imported files needs Plus or Pro; MemoFlow is a phone app, not a browser converter.

After reviewing and saving a transcript as a note, find it in note search. This iPhone screenshot shows the note list, not the import picker.

From file to note

The file is copied into MemoFlow, so it stays playable even if the original is moved or deleted.

  • In the recording library, choose the file import action and pick one audio or video file.
  • Check the recording's language. An import uses your default Speech Recognition Language; change it on the recording's page if the file is in another language.
  • Tap AI recognition. The page updates when the transcript is ready; Show speakers then separates the turns by speaker.
  • Save the transcript as a note. From then on its words appear in note search, and you can ask MemoFlow AI about it or generate a meeting summary from it.

Which files work

Supported audio: AAC, AMR, FLAC, M4A, MP3, OGG, OPUS, WAV and WMA. Supported video containers: AVI, FLV, MKV, MOV, MP4, MPEG, WEBM and WMV. A video must contain a decodable audio track. Only the audio is kept. Import one file at a time; protected, damaged or unsupported-codec files may be refused.

Format, size, and duration are separate checks

A supported extension does not guarantee that the audio inside can be decoded. File-size limits depend on the plan: Basic 50 MB, Plus 200 MB, and Pro 1 GB per file. A single imported recording can be up to 12 hours long. Check all three before starting a long import; recognition is a separate Plus or Pro action after the file enters the library.

Set the language before you tap

Recognition runs in the one language set on the recording. A file recognised in the wrong language does not stop with an error; it comes back as text in the language you chose, which can read fluently and still be wrong. If most of your files are in one language, set it as the default Speech Recognition Language once; for the odd file in another language, change it on that recording's page before starting recognition.

Mixed-language recordings are recognised in the selected language only, so pick the language most of the file is spoken in.

After recognition

The recording's page shows the transcript under the player, and Show speakers separates it by speaker. Save as note turns it into a regular note: it can be edited, found by note search, used as context for MemoFlow AI or a meeting summary, and exported as Word, PDF or Markdown.

The audio stays in the recording library, so you can play back the passage behind a line you are unsure about.

What an import does not get

An imported file is recognised after the fact, so there are no live captions and no Live Interpretation for it. Recognition runs in one language chosen by you; there is no automatic detection.

Limits to know

  • Basic can import and play files but cannot run AI recognition on them.
  • No web upload: MemoFlow runs on iPhone and Android only. Video frames are not transcribed.
  • A single imported recording can be up to 12 hours long; import may fail for protected, damaged, or unsupported-codec files.

Frequently asked questions

Is this a free online MP3-to-text converter?

No. MemoFlow is an iPhone and Android app. Files are imported in the app, and recognising them needs a Plus or Pro plan.

Does MemoFlow detect the language of the file?

No. It uses the language set on the recording, which starts as your default Speech Recognition Language. Check it before running recognition.

Can I import a video and transcribe its sound?

Yes. Import a supported video with a decodable audio track, then run AI recognition on the extracted audio. Video images are not analysed.
