Key Features
Everything you need to change audio pitch perfectly
Formant Preservation
Maintain natural voice characteristics when changing pitch. Turn male voices into female without chipmunk effects, or vice versa. Essential for realistic voice transformations.
Musical Intervals
Shift pitch by precise musical intervals - thirds, fourths, fifths, and octaves. Perfect for music transposition, harmony creation, and key changes.
Fine-Tuning Control
Adjust pitch in semitones and cents for precise control. Use high-quality Rubberband algorithm for professional results, especially at large pitch shifts.
9 Pitch Presets
Quick presets from octave down (-12) to octave up (+12), including thirds, fourths, and fifths. Perfect for common use cases like vocal harmonies and transposition.
High Quality Mode
Professional Rubberband algorithm delivers superior audio quality with minimal artifacts, even at extreme pitch shifts. Much better than basic resampling.
Privacy First
All pitch shifting happens in your browser using FFmpeg. Your audio files never leave your device. Perfect for sensitive or unreleased content.
Common Use Cases
Voice Transformation
Change voice pitch for content creation, anonymization, or creative projects. Use formant preservation to maintain natural voice quality when shifting from male to female voice or vice versa.
Music Transposition
Transpose songs to match your vocal range or change the key for different instruments. Perfect for karaoke, covers, and music practice.
Sound Design
Create unique sounds for games, videos, or music production. Shift pitch dramatically for monster voices, alien effects, or robotic sounds.
Vocal Harmonies
Create harmonies by shifting pitch by musical thirds, fourths, or fifths. Layer multiple pitched versions for rich vocal arrangements.

常见问题
什么是共振峰保留，什么时候应该使用它？
共振峰保留在更改音调时保持自然的语音特征。为逼真的声音变换启用它（男声转女声或反之）。对于创意效果或音乐转调，如果您想要自然的移调声音，请禁用它。
半音和音分有什么区别？
半音是八度的 12 个等分（像钢琴键）。音分是半音的 1/100，用于微调。例如，+1 半音 = +100 音分。音乐音程使用半音，精确调整使用音分。
我应该使用 Rubberband 还是重采样算法？
使用 Rubberband（高质量模式）以获得最佳结果，特别是对于大幅度移调、共振峰保留和专业工作。只有在需要快速处理且可以接受较低质量时才使用重采样（快速模式）。
我可以在不改变节奏的情况下移调音乐吗？
可以！移调只更改音调，同时保持原始节奏。这完美适用于将音乐转调以匹配您的音域或为不同乐器更改调号。如果您想更改节奏，请使用节奏调节器工具。
支持哪些文件格式？
我们支持所有常见的音频格式：MP3、WAV、FLAC、AAC、M4A、OGG、WMA、AIFF 等。您还可以从视频文件（MP4、AVI、MOV、MKV）中提取和移调音频。
我的文件安全私密吗？
绝对安全！所有移调都使用 FFmpeg 在您的浏览器中本地进行。您的音频文件永远不会离开您的设备或上传到任何服务器。完美适用于未发布的音乐或敏感内容。
