Reference-grade audio booster with dynamic equal-loudness, deep bass, treble damping, and stereo balance. CRANK: REFERENCE-GRADE AUDIO BOOSTER Engineered by CodeSpark Tech B.V. (KvK: 42053556) Most browser volume boosters destroy your sound, resulting in shrill, metallic, clipping distortion. Crank was built differently: a native, 32-bit floating-point DSP pipeline that protects your speakers while delivering deep, rich, analog-grade sound at up to 500% volume. ═══════════════════════════════════════════════ KEY ACOUSTIC FEATURES ═══════════════════════════════════════════════ • 500% MAXIMUM CLEAN GAIN Up to +14dB of linear volume amplification without digital truncation. • 30Hz INFRASONIC HIGH-PASS FILTER Filters out sub-audible mechanical mud that causes laptop speaker cones to rattle, freeing up +3dB of clean dynamic headroom. • DUAL-BAND TREBLE SHAPING Features an 8kHz high-shelf air curve for sparkle, paired with an automated 3.5kHz peaking notch to cut vocal sibilance and harshness. • LIVE AUDIO-REACTIVE STEREO VU METERS Dual 8-segment LED meters bounce in real time to the true RMS levels of your stream. • EXPANDABLE AUDIOPHILE DRAWER Slide out 3-band analog tone controls for surgical tuning: - BASS EQ: 220Hz warmth and body crossover (0 to +12dB) - TREBLE EQ: 8kHz air and high-end balance (-12 to +12dB) - PAN BALANCE: Smooth Left/Right stereo panning ═══════════════════════════════════════════════ PRIVACY & SYSTEM PERFORMANCE ═══════════════════════════════════════════════ • ZERO TRACKING & DATA COLLECTION We do not track, collect, transmit, or sell any user data or audio streams. All processing runs 100% locally in your browser. • 0.0% IDLE CPU DRAIN Visual VU meter streaming ports automatically disconnect when the popup is closed, conserving battery and CPU resources. ═══════════════════════════════════════════════ IMPORTANT LIMITATIONS ═══════════════════════════════════════════════ • DRM-Protected Streams: Crank cannot capture audio on premium streaming platforms (Netflix, Prime Video, Disney+) when browser hardware acceleration is active due to browser copyright protections. • Voice Calls: We advise against boosting Google Meet or Zoom calls without headphones to avoid acoustic feedback loops. ─────────────────────────────────────────────── Official Publisher: CodeSpark Tech B.V. • Amsterdam, NL Website: https://codesparktech.nl Privacy Policy: https://codesparktech.nl/privacy/
