What is Buzz Captions?
Buzz Captions turns spoken audio into text using Whisper speech-recognition models. The Windows application is part of Buzz Classic, the free, open-source desktop edition. Import an audio or video file to make a transcript, or use microphone input for live transcription. TXT output suits text-based work, while SRT and VTT exports provide subtitle files. Local models support offline transcription; the optional OpenAI Whisper API is a separate online processing option.
Choose a model with your computer's resources in mind. The publisher warns that Whisper is resource-intensive and microphone transcription may not keep up in real time, depending on the hardware, language and model size. The Windows package is also unsigned and can trigger a Windows security warning. This entry identifies the publisher-linked 1.4.5 Windows x64 ZIP archive on SourceForge, rather than the older 1.4.4 version listed on Softonic. The illustration is a publisher screenshot of the cross-platform Buzz Classic interface; window decorations can differ on Windows.
