android, audio filters

I would like to make audio records (via MediaRecorder/AudioRecorder) and then play recorded file with some changes (special effects) (e.g. increasing/decreasing speed, adding echo, mix with other predefined audio file,开发者_Python百科 etc)).

Do you have any suggestions how can I do that?

Do you have any interesting examples concerned this?

Hi I came across the following Api's which would be useful for you to remix a music piece. Equalizer to change the frequency. then try using BassBoost to change the Bass of the music.Finally , use the audiofix package.I hope this should get you going.
