iPEEH: Improving pitch estimation by enhancing harmonics

作者：

Highlights：

• The reason for pitch detection failures in frequency domain is analyzed: low HNR.

• We proposed to enhance the harmonics before detecting pitches.

• A detailed harmonics enhancement approach iPEEH is presented.

• Both theoretical evidence and implementation details for enhancement are provided.

• Comprehensive experiments are designed and versatility of iPEEH is verified.
