● Our Commitment to Audio Quality Note: Supports wide adjustment range (25%–400% tempo / ±1 octave pitch). Due to the nature of digital audio, extreme settings may result in artifacts, which can often be mitigated by enabling ”High Quality Mode” in the options menu.
1. Automatic Frequency Compensation: Automatically compensates for weak bass when pitch is raised or weak treble when lowered, mitigating common shifter issues. 2. Attack Clarity Enhancement: Suppresses the "doubling" effect often heard in the attack of drums and percussion when altering pitch or tempo. 3. Flexible Export Settings: Select MP3 bit rates from 96 to 320 kbps to find your perfect balance between storage space and audio quality. 4. Formant Shift: Natural-sounding voice transformation via our C++ engine (Updated April 2026). Adjust "Voice Texture (Cepstral)" to change voice resolution—higher for rich ensembles, lower to eliminate solo noise. The "Auto" button instantly calculates the ideal texture. ■ Advanced Formant Detail Controls (June 2026): - Cepstral Envelope Fade: Smooths transitions near cepstral coefficients for natural results. (Off: more pronounced formant changes, but may sound unnatural.) - High-Frequency Protection: Prevents over-processing of high-frequency audio. (Off: full formant shift extends to upper range, potentially making breath noise or cymbals harsh.) - Low-Energy Frame Bypass: Skips silent frames to avoid noise amplification. (Off: full-intensity formant shifting applied at all volume levels.) 5. Vocal Extraction & Removal: Center-cancel function to extract or remove vocals. (Does not apply to tracks where vocals are panned fully left or right.) 6. Track Decomposition: Analyzes and isolates sounds based on their stereo positioning/panning. (Precision depends heavily on original audio quality.) 7. Micro-Pitch, Micro-Formant (Apr. 2026): Precision shifting in 5-cent increments (1/20th of a semitone). Perfect for correcting digitized vinyl/tape drift or fine-tuning instruments without losing character. 8. High-Quality Mode: Advanced mode using Phase Vocoder for clearer changes while maintaining sound richness. (Requires more processing time). 9. Spot Pitch Correction: Select specific waveform areas and apply pitch correction only to those spots. Video Guide: https://youtube.com/shorts/I1BFM18fjDw 10. Practice Session Save (April, 2026): Save perfect practice settings as presets, store custom adjustments, and bookmark specific playback ranges/loop points per song.
Professional processing made easy without a DAW.

Final, I have found my dream app. I tried other apps before, but they were arrogantly doing jobs which were not even described in their given names. But this app only does what supposed to be done according to its name. It's really easy, fast and affordable to use. Its features are all accurate 100% and amazing. Thanks for the great job keep it up👍

Excellent and easy results. Pitch changing has never been so easy. Great work dear developers.

Full of ads. Good ideas but most options bug out or conflict with each other. Recommend implementing a better algorithm overall as this is very amateur.
★☆☆☆☆suki· Mar 1, 2026
Terrible. So many ads, it's insulting. Terrible quality. Butchers the audio as well. DO NOT WASTE YOUR TIME.
