Core Audio Technologies
- Vocal Frequency Boost: Human speech primarily resides between 300Hz and 3400Hz. We use BiquadFilterNodes to EQ and isolate this exact frequency range, bringing voices to the forefront.
- Dynamic Compression: When amplifying ambient sounds, sudden loud noises (like dropping a plate) can be painful. Our built-in DynamicsCompressorNode acts as an acoustic airbag, instantly suppressing high-decibel spikes to protect your eardrums.
- Ultra-Low Latency: By disabling unnecessary software echo cancellation and configuring hardware latency hints, we reduce the mic-to-headphone delay to near-zero, enabling seamless face-to-face communication.
