V3.2: The Musician’s "Superpower" Toolbox Is Here!

From ultra-precise tuning to fretboard muscle memory, all the way to cinematic-grade audio noise reduction—three killer instrument and audio tools designed to supercharge your creation and practice from every angle.

Dear instrumentalists and content creators—thanks for waiting! We know that on the journey toward musical perfection, every cent of pitch accuracy, every bit of fretboard memory, and every second of audio quality truly matters. Today, we’re officially launching three professional-grade online tools. No downloads required—just open your browser and switch on “Master Mode.”

Chromatic Tuner: Extreme Precision Down to the Finest Detail

Whether you play guitar, piano, ukulele, or even rare traditional instruments, the Chromatic Tuner has you covered.

  • Ultra-wide detection range: Supports an exceptionally broad range from A0A_0 to G9#G_9^\#, covering virtually all instruments.
  • Millisecond-level feedback: Real-time detection powered by Web Audio, combined with a red–yellow–green scale, makes cent deviations instantly clear.
  • Intelligent gain control: Is the sound source far away? No problem. The system automatically adjusts input gain to ensure accurate detection even in complex environments.

Fretboard Trainer: Ditch Memorization and Build True Muscle Memory

Want to navigate the fretboard like a master? The Fretboard Trainer is your secret weapon.

  • Real-time interactive feedback: Play your actual instrument while the microphone captures pitch—correct or incorrect results are shown instantly, creating an efficient feedback loop.
  • Deep customization: Train on a single string, multiple strings, or the entire fretboard, with customizable fret ranges (0–22 frets) to precisely target weak spots.
  • Advanced challenge mode: Enable the “Octave Accuracy Required” option to rigorously strengthen your sense of absolute pitch positioning.
  • Flexible visual notation: Switch freely between sharps and flats to match different music theory preferences.

Audio Noise Reduction: One Click, Total Silence

Noisy environment? Air conditioner too loud? The Audio Noise Reduction tool uses cutting-edge AI technology to rescue your recordings.

  • DeepFilterNet3 at its best: Unlike cheap, destructive noise reduction, our deep filtering approach removes noise while preserving the natural character of the human voice.
  • Blazing-fast processing: A 1-minute audio file can be processed in about 15 seconds—astonishingly efficient.
  • Local WASM magic: Powered by WebAssembly, all heavy deep-learning computation happens locally in your browser—no file uploads required, protecting your privacy and saving bandwidth.
  • High-fidelity export: Supports lossless WAV and efficient MP3 formats, instantly giving your podcasts and recordings a professional broadcast-quality finish.

Come try these three powerful tools today and make your musical life simpler, more efficient, and more inspiring.
