Systems and methods for adjusting pitch of an audio signal include detecting input notes in the audio signal, mapping the input notes to corresponding output notes, each output note having an associated upper note boundary and lower note boundary, and modifying at least one of the upper note boundary and the lower note boundary of at least one output note in response to previously received input notes. Pitch of the input notes may be shifted to match an associated pitch of corresponding output notes. Delay of the pitch shifting process may be dynamically adjusted based on detected stability ofthe input notes. 本发明提供了一种用于调整音频信号的音调的系统和方法，该方法包括：检测所述音频信号中的输入音符、将所述输入音符映射到相应的输出音符，每个输出音符具有相关联的上音符边界和下音符边界以及响应于先前接收到的输入音符来修改至少一个输出音符的所述上音符边界和所述下音符边界中的至少一个。所述输入音符的音调可被转变以匹配相应的输出音符的相关联的音调。基于检测到的所述输入音符的稳定性来动态地调整所述音调转变过程的延迟。
