### Speaker Tester & Cleaner: Fix Sound, Boost Volume

This Chrome extension offers a comprehensive solution to test and enhance your phone's speaker performance. It features both manual and automatic speaker testing modes, utilizing a frequency generator to analyze audio quality across a range of frequencies. Whether you're evaluating new speakers or diagnosing your phone's ear and loud speakers, this app helps you detect audio issues and improve sound clarity.

Key features include the ability to generate sine wave frequencies for testing, an automatic speaker test with ratings on a 1-5 star scale, and a speaker cleaner function that boosts performance by clearing audio memory.
