Finds the key and applies real-time transpose and pitch shift to YouTube audio with on-device analysis and formant correction. moduLab helps musicians, singers, and learners find the key of music and apply real-time transpose and pitch shift while it plays in YouTube or YouTube Music. Tonal analysis runs entirely on your device with Sonance (LH). Features • Detect the tonal center, major/minor mode, confidence, an alternate result, and analyzed coverage. • Transpose and pitch-shift audio in real time from -12 to +12 semitones. • Preserve vocal character with optional formant correction and automatic or manual voice-base control. • Use Bypass to pass captured audio through without pitch or formant processing. • Pause tonal analysis during detected ads while audio processing remains active. • Store settings and derived tonal results locally so a previous result can appear when you revisit a track. Privacy • Sonance (LH) analyzes audio entirely on your device. • Selected-tab audio stays in memory during processing and is not sent to moduLab or any remote analysis service. • moduLab does not access your microphone, require an account or Google sign-in, sell user data, or use user data for advertising. Usage Open a supported YouTube or YouTube Music tab and click the extension icon. Starting processing may restart the current track from the beginning for a clean analysis. While processing is active, Chrome tab capture replaces the tab’s original audio output with moduLab’s processed output. moduLab is not affiliated with or endorsed by YouTube or Google.
