Research optimizing media file format for transcriptions

[citomcclure]

User Story

As a voice note user, I may want the fastest voice note transcription possible instead of a slower one with more confidence.

Overview

Research which, if any, media file formats affect transcription job times in Amazon Transcribe. Currently, WAV with PCM 16-bit encoding is a larger file format than most and may be overkill for simple notes. Ultimately, this could result in toggle between faster, lower quality notes and slower, higher quality ones. If not prior research exists, we can implement 2-3 other file formats (research length of time to do so) and measure/benchmark the transcription times in a repeatable environment/way.
