KF0

KF0 is a pitch (F0) extractor for speech signal. I have spent a long time trying to develope a stable pitch detection algorithm. Many different techniques have been tried, e.g. autocorrelation, instantaneous frequency, wavelet transform, constant Q transform, etc. and the techniques used in KF0 have been improved significantly over the last 10 years. You are welcome to have a try. Any comments/feedbacks will be highly appreciated.

KMusic

KMusic is a software to eliminate/reduce vocals from stereo songs in any CD albums. This software allows you to create your own karaoke music via two simple steps, 1) put your CD in and rip your favorite songs out using Kmuisc; 2) right click the song on the track list then select "Extract Music" in the pop-up window.
Please note that the CD Ripper interface of this software is copied from a free software, whilst the core vocal removal technology is developed by myself.
