Speaker 1Okay, quick note after the client call. They want the second option, but with the cheaper flooring.

Speaker 1Also, remind Marta about the measurements for the kitchen window.
Where your M4A file probably came from
If you recorded on an iPhone or Mac with Voice Memos, the file is M4A. Zoom saves an M4A audio track next to the MP4 video for every recording. Many Android recorder apps also save M4A because AAC gives good quality at small file sizes.
All of these upload as they are. You don't need to rename the file or convert it to MP3 first.
Why M4A is a good format for transcription
AAC inside M4A keeps speech clear at modest bitrates, so a one-hour recording stays small enough to upload quickly even on mobile data. That makes M4A a sensible choice when you record meetings or interviews on a phone.
If another app in your workflow only accepts MP3, the free browser converter on this site turns M4A into MP3 or WAV on your own device, without uploading anything.

Frequently asked questions
Do I need to convert M4A to MP3 before transcribing?
No. M4A is accepted directly. Convert only if another tool needs MP3, and you can do that in your browser with the free converter on this site.
Can I transcribe an M4A file on my iPhone?
Yes. Save the recording to Files, open this page in Safari and choose the file from the upload box.
Is M4A to text free?
Files up to 30 minutes are free without an account, up to 120 minutes per month. Longer files, up to 10 hours, need Pro.
What about Apple Lossless M4A files?
M4A files with ALAC audio are larger than AAC ones. If an upload is slow, convert the file to MP3 in the browser first; for speech the difference won't matter.
Are my recordings kept?
Only for the retention period you choose. Files are never used to train AI models.
