      Transcription – Supported File Types

      This article contains information about which media file types are supported for the Transcription feature.

      You can use Reveal to transcribe audio and video files into linked searchable text.

      • Source files must be in FLAC, MP3, MP4, Ogg, WebM, AMR, or WAV file format.

        NOTE: Although Reveal Review can transcribe FLAC and AMR file types, they are not currently supported by our in-browser media player.
      • For AMR, Amazon Transcribe supports both Adaptive Multi-Rate Wideband (AMR-WB) and Adaptive Multi-Rate Narrowband (AMR-NB) codecs.
      • For the Ogg and WebM file formats, Amazon Transcribe supports the Opus codec.

      For best results:

      • Use a lossless format. You can choose either FLAC, or WAV with PCM 16-bit encoding.

      • Use a sample rate of 8,000 Hz for telephone audio.

      NOTE:  There is no limitation to Transcribe service calls.
