━━━━━━━━━━━━━━━━━━━━━━ Features ━━━━━━━━━━━━━━━━━━━━━━

★ Pitch Change: Transpose within a range of -12 to +12 semitones. Precise adjustments are possible in 0.1 semitone increments. Pitch correction maintains a natural sound quality even when changing keys.

★ Speed ​​Change: Adjust from 0.5x (half speed) to 2.0x (double speed) in 0.01x increments. Practice fast passages in slow motion or challenge yourself with a faster tempo.

★ Independent Control: SonicShift's greatest feature: Pitch and speed are completely independent. Lowering the key doesn't change the tempo. Raising the tempo doesn't change the key. No compromises.

★ Real-time waveform display: Visualizes the music being played using FFT. 40 animation bars move in real time according to the frequency.

★ Quick presets: Supports 7 frequently used scenes: • Half-step down/up (±1 half-step) • Whole-step down (-2 half-steps) • Slow practice (0.75x speed) • Super slow (0.5x speed) • Karaoke ±3 half-steps

★ Haptic feedback: Features haptic feedback on slider operation. You can feel the moment you return to the original key or normal speed, allowing for intuitive operation.

★ Multi-format support: Supports major music file formats: MP3, WAV, M4A, FLAC, OGG.
