Question 1

Can I upload MP3, WAV, M4A, OGG, OPUS, and WebM?

Accepted Answer

Yes, these common audio formats are supported for short files when the underlying audio is readable. Some files with familiar extensions may still fail if they are damaged or encoded unusually.

Question 2

Should I convert my file before upload?

Accepted Answer

Usually no. If the original file is already supported, upload it directly. Converting repeatedly can increase file size or reduce speech detail without improving the transcript.

Question 3

Why does an OGG or OPUS file matter?

Accepted Answer

Messaging apps often use OGG or OPUS because they are efficient for speech. VoiceNoteToText supports common voice-note formats so you usually do not need to convert them first.

Question 4

Why did the upload fail after I selected a file?

Accepted Answer

The file may exceed current limits, use an unsupported codec, be damaged, or fail because the network connection dropped. Try a smaller clip and re-export the original if needed.

Question 5

Can I upload multiple files at once?

Accepted Answer

The current core workflow is designed around one audio file at a time. This keeps review simple and makes it easier to understand which transcript belongs to which recording.
