Task"Transcribe", "Translate""Transcribe""Transcribe" converts the input audio into text in the selected language, while "Translate" converts it into text in English.
LanguageSee Whisper's documentation for the full list of supported languages"Detect Language""Detect Language" will try to detect the spoken language in the audio based on the first few seconds. However, selecting a language is recommended (if known) as it will improve transcription quality in many cases.
Quality"Very Low", "Low", "Medium", "High""Very Low"The transcription quality determines the Whisper model used for transcription. "Very Low" uses the "tiny" model; "Low" uses the "base" model; "Medium" uses the "small" model; and "High" uses the "medium" model. The larger models produce higher-quality transcriptions, but require more system resources. See Whisper's documentation for more information about the models.

Record audio playing from computer (macOS)​

To record audio playing from an application on your computer, you may install an audio loopback driver (a program that lets you create virtual audio devices). The rest of this guide will use BlackHole on Mac, but you can use other alternatives for your operating system ( see LoopBeAudio, LoopBack, and Virtual Audio Cable).

  1. Install BlackHole via Homebrew

    brew install blackhole-2ch

  2. Open Audio MIDI Setup from Spotlight or from /Applications/Utilities/Audio Midi Setup.app.

    Open Audio MIDI Setup from Spotlight

  3. Click the '+' icon at the lower left corner and select 'Create Multi-Output Device'.

    Create multi-output device

  4. Add your default speaker and BlackHole to the multi-output device.
