We accept most digital audio formats. These include: wav, mp3, mp4, ogg, aiff, aif, m4a, mov, wma, avi, flv, 3gp, 3gpp, 3ga, amr, caf, m4v, mxf. As a rule of thumb, if you can play a media file on your computer, we should be able to transcribe it. Advanced users, please note that if your file format is not explicitly supported by the TranscribeMe Portal, you can rename the file extension to .mp3 and try to upload to the Customer Portal Account again. TranscribeMe continues to add supported file formats over time and we will do our best to process your file.
