Audio Toolkit for YouTube

Take control of your YouTube audio. Have you ever been frustrated by quiet videos, or startled by sudden loud ads and sound effects at night? Audio Toolkit for YouTube is a lightweight audio tool that lets you fine-tune sound directly from the YouTube player. It works instantly right after installation with no extra setup required. ■ Perfect for you if: • You find the audio too quiet even at maximum volume. • You constantly adjust the volume at night due to sudden loud ads or sound effects. • You watch or listen with only one earbud. • The audio balance feels tilted to one side. ■ Key Features • Volume Boost: Amplifies sound up to 200%, bypassing YouTube's default 100% limit. • Compressor (Night Mode): Reduces volume fluctuations by suppressing loud noises for comfortable late-night listening. Instantly toggle on/off with the player bar icon. • L/R Balance: Adjusts the audio balance between the left and right channels. • Mono Merge: Combines left and right channels into one, delivering complete sound even through a single earbud. ■ How to Use • Toggle the Compressor directly using the equalizer icon next to the volume control on the player bar (the icon turns red when active). • Adjust Volume Boost, Balance, and Mono settings by clicking the extension icon in your browser's toolbar. • All settings are automatically saved and applied to your next viewing session. ■ Lightweight & Safe • All audio processing is done entirely within your browser. • We do not collect or transmit any personal information, including watch history or account details. • This is a completely free extension with no ads. ※ This extension is an unofficial tool and is not affiliated with YouTube or Google.
