TalkSound — Voice Content Audio Enhancer

Stereo widening, room ambience, loudness leveling and anti-fatigue EQ for online courses, podcasts and talk shows. 100% local.

TalkSound enhances the audio of voice-focused content — online courses, podcasts, talk shows and interviews — directly in your browser. Common problems it fixes: mono recordings that cause listening fatigue, over-compressed audio, harsh mid-high frequencies, uneven speaker levels, and volume jumps between videos. Features: - 5 one-tap presets (Classroom, Panel Balance, Warm Voice, Anti-Fatigue, Bypass for A/B) - Balanced stereo widening and room ambience (built-in and custom impulse responses) - Speaker leveling and auto loudness (targets −16 LUFS across videos) - De-esser for harsh sibilance - Real-time input vs output spectrum and level meters - Keyboard shortcut (Ctrl/⌘+Shift+9), per-site memory, auto-enable on learning platforms Works on any tab that plays audio — YouTube, Udemy, Coursera and more. 100% local processing: no audio or data ever leaves your device.
