# AutoEQ ### AutoEQ is an open-source project. {% embed url="" %} AutoEQ analyzes the characteristics of earphones and headphones through actual measurements using specialized equipment. Based on this data, it creates EQ presets that bring the sound closer to a reference target. The Qudelix app integrates this vast database of AutoEQ presets, providing a user interface that allows these presets to be applied directly to the device with simple adjustments. From an analog and acoustic perspective, it is nearly impossible to achieve perfect response across all frequency ranges for all earphones and headphones. Engineering is a continuous process of trade-offs. When you gain something, you inevitably lose something else. Using AutoEQ to compensate for shortcomings in well-designed earphones and headphones is a very reasonable approach. Especially for digital audio sources, a precise DSP EQ processor has almost no negative impact on sound quality. {% hint style="info" %} \*Some may think that AutoEQ adjusts the sound to match the earphones or headphones they are using, but this is a misunderstanding. Only AutoEQ presets that specifically match the exact model of your earphones or headphones should be selected/applied. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
