Troubleshooting: What to do when m4a file transcription fails or doesn't work

Here are solutions for common issues encountered when transcribing m4a files.

If the video file size is too large

M4a files recorded with iPhone Voice Memos are typically only tens of MB even for an hour, so file size is rarely an issue.

However, if you record videos with your iPhone camera, even a few minutes of video can quickly exceed 1GB.

With Mr. Transcription, if you upload a video file larger than 100MB, it automatically extracts only the audio from the video.

Removing the video data dramatically reduces the file size, allowing for smooth transcription.

Furthermore, the conversion process happens directly in your browser, eliminating the need to send files to a server.

This ensures that highly confidential data, such as internal meeting videos, can be used with peace of mind.

When the m4a file recording time is too long

Mr. Transcription has a recording time limit per file for each plan.

• Free (non-member): 3 minutes
• Free member: 10 minutes
• Basic plan: 90 minutes
• Value plan: 3 hours
• Premium plan: 5 hours

If the recording exceeds the limit, please split the m4a file before uploading.

※You can check the fees for each plan on the Pricing Plans page.

When using a site or app that does not support m4a files

Some AI transcription sites and apps may not support m4a files.

In such cases, you can convert the m4a file to mp3 or wav and then upload it.

However, this requires extra conversion steps, so it's recommended to choose a service that supports m4a from the start.

When the file format recorded with Voice Memos is not m4a

iOS 26 Voice Memos added a "Recording Mode" setting.

If you record in "Spatial" mode, it may be saved in ".qta" format.

Unlike m4a files, many apps and sites cannot read qta files, so it's recommended to check the file extension if you can't upload it.

To set the saving format to m4a, go to "Settings" app → "Apps" → "Voice Memos" and change the recording mode to "Mono".

After this setting, subsequent recordings will be saved in m4a format.

What is an M4A File? Characteristics of Voice Memo Audio Files

An M4A file is a file format used for storing audio and music.

It's a type of "MP4 file" used for videos and audio, and is primarily used with Apple products like iPhone, iPad, and Mac.

When you record with Voice Memos on an iPhone or iPad (iOS), it is typically saved as an M4A file.

Even when recorded with Sound Recorder on a Windows PC, it's saved in M4A format, making it a widely encountered file type.

However, unlike widely used formats such as MP3 or WAV, M4A files may not be readable by some apps or websites.

Therefore, when transcribing M4A files, it's recommended to use an AI transcription service that supports M4A.

With a transcription app that supports M4A files, you don't need to convert files recorded on your iPhone; you can simply upload them directly from the Voice Memos app to transcribe them.
