Does pitch shifting change the speed?

No. This tool uses "Time Stretching" technology to change the pitch (key) while keeping the original tempo/speed exactly the same.

A semitone is the smallest step in Western music (e.g., from C to C#). Shifting +12 semitones moves the audio up exactly one full octave.

Can I key-change my karaoke tracks?

Yes! This is the primary use case. If a song is too high or low for your voice, you can shift it by -2 or +2 semitones to find your perfect range.

Does it sound robotic?

Small shifts (±1-4 semitones) sound very natural. large shifts (>7 semitones) can start to sound processed or "chipmunk-like" due to the nature of vocal formants.

常见问题

不会。此工具使用「时间拉伸」技术来改变音调（调式），同时保持原始节奏/速度完全相同。

半音是西方音乐中最小的步进（例如，从C到C#）。移动+12个半音将音频向上移动这好一个八度。

可以！这是主要用例。如果一首歌对您的声音来说太高或太低，您可以将其移动-2或+2个半音以找到您的完美音域。

小幅度的移动（±1-4个半音）听起来非常自然。大幅度的移动（>7个半音）可能会由于人声共振峰的性质而开始听起来经过处理或像「花栗鼠」。
