I am using Samsung Galaxy S7 and recently, I used the speech-to-text feature in the default Voice Recorder application. When I play one of the audio files that was recorded with that feature, the application is able to show the text in sync with the audio. I saw that there was the text stored in another text file together with the audio file, but it was just the raw text. I'm trying to figure out how this works. Is this information for syncing the text and audio stored in the audio file? In this case, all the recordings are only in M4A files. Hence, I tried searching what M4A files can store, like if they can store subtitles because it would seem that it could be subtitles that enable this syncing. However, I can't seem to find any information on this. Or it could also be that the application just has this information stored in some sort of storage or cache, which would mean that if I moved the files over to my computer, there would not be any text synced with the audio.

I don't seem to find the recorded files on my Samsung Galaxy S6. What is the file path to the saved recording files? Google doesn't tell me the answer.

I have a Samsung Galaxy S8+ phone. I use the Voice Recorder app a lot and I also add several bookmarks to each file. Now, my phone is out of storage space and I need to back up my old recorded files to a computer. Although I know how to find the **m4a files** in my phone storage, I cannot find the **corresponding bookmarks** for each file. So, my question is: - Where can I find these bookmarks in my phone storage? If it is embedded in m4a files, how can I see them on my Windows PC? - If it is only seeable in the same app, does it mean that if I move the files to my computer, I can access the file and its bookmarks whenever I move a copy of it to the recorder app on my phone?

I need to convert my M4A audio files to M4A but with a 3GP4 codec (it seems Samsung audio recording app only recognizes those with a 3GP4 codec). How can I do that with ffmpeg or any other program? I tried: ffmpeg -i input.m4a -brand "3gp4" output.m4a This did change the major brand to 3gp4, but the Samsung Recorder app still doesn't recognize the audio file.
