Voice memo workflow
iPhone Voice Memos exports as M4A. Android voice recorder apps default to MP3 or M4A. WhatsApp voice notes export as OGG (file extension may show as .opus). All work in mdisbetter — paste the file in, get the text back. Useful for: capturing brainstorms while driving, dictating drafts of emails or documents, recording quick reminders, capturing meeting notes when typing isn't practical, journaling by voice.
Single-speaker accuracy
Voice memos are the easiest case for speech recognition: single speaker, usually close to the mic, usually consistent audio quality throughout the recording. Expect 95-98% accuracy on a typical voice memo recorded in a normal indoor environment. The output is flat text with paragraph breaks — copy-paste-ready into Notion, email, anywhere you want the words.
From voice memo to action
Common pattern: record a voice brainstorm while walking, transcribe via mdisbetter, paste the text into ChatGPT/Claude with "structure these notes into a coherent outline" or "extract action items from this brain dump". The voice-to-text step is the bottleneck removal — without it, the brainstorm dies in the voice memo app; with it, the brainstorm becomes structured work product within minutes of getting back to your laptop.
