Checking an M4A recording
M4A is a file container, and recordings can use different audio codecs. The extension alone does not guarantee that the file can be read. Renaming another file to .m4a does not convert it.
- Upload the original M4A export rather than a renamed copy.
- Check that the recording contains intelligible speech and fits the duration limit shown above.
- Review names, numbers and quiet passages against the original audio before using the transcript.
