pitch-shifting

I need to modify pitch or tempo of an audio, but need to do them separately. Is there any example in Android for that or any library which provides support for Android. I want to avoid using NDK/JNI for this, since I am not that good into it. I have already seen Many libraries, although they have a nice tutorial, but I am unable to import them to Eclipse Android project. Help is appreciated :-) you could try Tarsos ! Here some cool demo links from Tarsos: http://0110.be/posts/Phase_Vocoding%3A_Time_Stretching_and_Pitch_Shifting_with_TarsosDSP_Java http://0110.be/posts/Pitch_Shifting_-

I have a sound file I would like to modify the pitch of. The file is stored in an MP3. I have searched the internet but have been unsuccessful in finding any libraries or algorithms that would allow me to modify the pitch. Any examples and/or literature would be appreciated Erik J It's not really clear from your question whether you only want to change the playback speed (like the pitch fader on a turntable does) or whether you want to change the pitch without affecting the playback speed. If the latter, you need to use a time stretching/pitch shifting algorithm. See: http://en.wikipedia.org

My group is developing a simple MATLAB Graphical User Interface (GUI) that is supposed to record audio from a microphone - plugged in or built in to the computer - and play back the signal. So far we have that completed. Our GUI also can load a sample (a .wav file, etc..) and play it back using the same "Play" pushbutton on the GUI. We have a Play, Record, Load, and Save push button. Now for the pitch-shifting of loaded or recorded samples... We know we need a peak-picking algorithm to find the fundamental frequencies of the signals. We were then thinking that we could multiply each of those

I'm a beginner learning javascript. I've got various projects in mind with an interactive page on my site related to microtonal frequencies and planetary frequencies. I need to be able to play my audio sample .wav file in a loop but have the audio sample timestretched with a corresponding change in pitch. I tried myAudio.playbackRate = 0.5; which plays the audio 0.5 slower but keeps pitch same. I researched and found something. But how do i set preservesPitch to false or true? And this only works in 'Google Chrome' I think, so other program i found is here : https://github.com/janesconference
