Audio to Text · Sonorix
Transcribe audio to text without replaying every minute.
Upload a recording, let Sonorix detect the language, and turn spoken words into editable text. The free tool is built for real work: interviews, meetings, property calls and voice notes.
Why this workflow matters
Manual transcription is slow because you repeatedly pause, rewind and correct names. A useful workflow should accept the file formats people already have, produce readable text, and make the result easy to copy into the next task.
What you can do
Common audio and video formats
Upload MP3, M4A, WAV, AAC, OGG, OPUS, FLAC, MP4, MOV, WEBM and other supported formats.
Automatic language detection
You do not need to choose a language before every upload. Clear speech and lower background noise improve accuracy.
Continue from transcript to action
Copy the text, or use Sonorix Real Estate to extract buyer budget, locality, timeline and follow-up actions from a property conversation.
