Where to find your voice memo file

Every device stores recordings a little differently. Get the file out once - IronMemo takes it from there, audio or video alike.

iP

iPhone Voice Memos

  1. 1Open Voice Memos, pick the recording, then tap the three-dot button and choose Share.
  2. 2Select Save to Files, or AirDrop it to your Mac - the memo exports as an M4A file.
  3. 3Upload that M4A to IronMemo as is - no conversion needed.

iOS 18+ shows a built-in transcript on iPhone 12 and newer, but it covers a limited language list and does not label speakers - see the comparison below.

An

Android voice recorders

  1. 1In Samsung Voice Recorder or Google Recorder on Pixel, open the recording and tap Share.
  2. 2Send the file to your email or cloud drive, or copy it from the Recordings folder over USB.
  3. 3Upload the exported M4A to IronMemo.

Built-in phone transcripts cover a limited set of languages; on Pixel, speaker labels work in English only.

Vr

Olympus, Sony and other dictaphones

  1. 1Connect the recorder over USB - modern Olympus / OM System and Sony models mount as a flash drive.
  2. 2Drag the MP3 or WAV files onto your computer.
  3. 3Upload them to IronMemo - both formats are supported natively.

Older dictaphones record WMA - convert those files to MP3 first, then upload.

H

Zoom H-series and field recorders

  1. 1Take out the SD card, or plug the recorder in over USB in card-reader mode.
  2. 2Copy the WAV or MP3 tracks to your computer.
  3. 3Upload - an uncompressed multi-hour WAV still fits within the 2 GB limit.
Pl

Plaud Note and NotePin

  1. 1In the Plaud app, open your recording and choose to export the audio.
  2. 2Save it as MP3 (any platform) or WAV (mobile app).
  3. 3Upload the exported file to IronMemo.

Audio export is available on every Plaud plan, including the free tier.

Tg

Telegram voice messages

  1. 1In Telegram Desktop, right-click the voice message and choose Save As - it exports as an OGG file.
  2. 2On mobile, forward the message to Saved Messages first, then save the file from Telegram Desktop.
  3. 3Upload the OGG to IronMemo - it is supported directly.

Telegram does not record calls itself - this works for the voice and video messages already in your chats.

Wa

WhatsApp voice notes

  1. 1On iPhone: long-press the voice message, tap Forward, then the share icon and Save to Files.
  2. 2On Android: voice notes sit in the WhatsApp/Media/WhatsApp Audio folder - copy the file with any file manager.
  3. 3Upload the saved OPUS file to IronMemo - it is accepted directly, no conversion.

WhatsApp voice notes are Opus audio (.opus). IronMemo takes them as is - along with OGG voice messages from Telegram.

What you get back

Not a wall of text - a structured document you can search, check and share.

1

Transcript with speaker labels

Full text with speakers separated and timestamps on every segment - in any of 30+ languages, even when people switch languages mid-sentence.

2

Summary and action items

A concise summary with decisions and to-dos pulled out - each point linked to the exact moment in the recording, so every claim is checkable.

3

A searchable knowledge base

Memos stop dying in the recorder. Transcripts land in one workspace where you can search, ask questions and connect notes across recordings.

Supports MP3, M4A, WAV, OGG, OPUS, MP4, WebM and more - files up to 2 GB, so multi-hour recordings fit.

Built for long recordings, not clip-length demos

Most voice memo tools meter minutes and cap file sizes. IronMemo is set up the other way around.

2 GB

per file

A multi-hour dictaphone session uploads as one file - no splitting, timestamps stay continuous.

30+

languages

The best model is picked per language, and mid-sentence language switches are handled.

0

minute caps on free

The free plan does not meter transcription minutes - upload the whole recording, not a 30-minute slice.

Your phone's built-in transcript vs. IronMemo

iPhones and Pixels now transcribe memos on-device. Honest take: sometimes that is enough - and sometimes it is not.

Built-in phone transcription

  • Free and on-device - great for a quick personal note.
  • Covers a limited list of languages.
  • Speaker labels are missing on iPhone and English-only on Pixel.
  • Needs a recent phone model - iPhone 12 or newer, Pixel 6 or newer.

Upload to IronMemo

  • 30+ languages with the best model per language - mixed-language memos included.
  • Speaker labels in any supported language, not just English.
  • Summary and action items tied to timestamps, ready to share as a document.
  • Takes files from any device - phone, dictaphone, field recorder or messenger.

For a short personal note in a major language, the built-in transcript on your phone is honestly enough. IronMemo earns its place when recordings are long, involve several speakers or languages, or need to become a searchable, shareable document.

Voice memo transcription - FAQ

MP3, M4A, WAV, OGG, OPUS, MP4, WebM and other common audio and video formats, up to 2 GB per file. That covers iPhone and Android memos (M4A), dictaphones (MP3, WAV), field recorders (WAV) and voice notes from WhatsApp (OPUS) or Telegram (OGG). WMA files from older dictaphones need converting to MP3 first.

In Voice Memos, pick the recording, choose Share, then Save to Files or AirDrop - you get an M4A file. Upload it to IronMemo and the transcript, speakers, summary and action items come back in minutes. Nothing to install - it works from the browser.

Files up to 2 GB are accepted, which fits multi-hour recordings. The free plan does not meter transcription minutes, so a two-hour interview does not have to be cut into pieces. Timestamps stay continuous across the whole recording.

Yes. IronMemo supports 30+ languages and picks the best model for each. If you switch languages mid-recording - dictating in English, then quoting in Russian or Spanish - the switch is detected and each segment is transcribed with the right model.

No. Your recordings and transcripts are never used to train or fine-tune AI models - they are processed only to produce your results. You can export or delete everything at any time; the details live on the Security page.
