SayItAgainSlower

SayItAgain is an Apple iPhone or iPad app used when transcribing audio recordings, i.e., listening to a recording while typing out what is heard into a text editor. SayItAgain will play back your audio recording and allow you to slow it down and back up to replay with the tap of a button or press of a foot pedal. This is similar to the old Panasonic RR-830 Standard Cassette Transcriber. You then use your fingers on a keyboard and type in the corrections! You can use Notes, TextEdit, MS Word, Emacs, or whatever text editor you are most familiar with.
For example, perhaps you submitted your parents Story Of A Lifetime to one of the automated transcription tools, like OpenAI Whisper or Google Speech-to-Text, and found that the results were riddled with errors. You now must go through and manually correct the errors, get the proper names right, work out that deep Kentucky accent. SayItAgain is perfect for this.
You will need to have your audio file(s) local in your iPhone music library for SayItAgain to be able to process it. SayItAgain will not work with cloud-based music services like Spotify.
SayItAgain is a free app. I have released the SwiftUI source code to github. If you make any changes I would appreciate you letting me know so I can consider adding them.
