What is MP1, and how do you transcribe it?
MP1 (MPEG-1 Layer I) is an audio format you'll typically find from rare early digital audio. The seldom-seen sibling of MP2/MP3; decodes fine where it survives.
To turn it into text you don't need to convert anything first — upload the MP1 file (or paste a link) and Whipscribe returns a clean transcript with speaker labels and per-word timestamps, exportable to TXT, SRT, VTT, or DOCX. Everything runs on private infrastructure that never hands your file to a third-party AI service.
