Thus the two effects cannot be separated when using this method. Slowing down the recording to increase duration also lowers the pitch, speeding it up for a shorter duration also raises the pitch creating the Chipmunk effect. Unfortunately, the frequencies in the recording are always scaled at the same ratio as the speed, transposing its perceived pitch up or down in the process. For a digital audio recording, this can be accomplished through sample rate conversion. So all you have to do is select the notes you want delete the press the “fn” key on the bottom left of your keyboard and while holding the fn key press delete to delete the notes.The simplest way to change the duration or pitch of an audio recording is to change the playback speed. How do you select and delete in FL Studio?

Round – Rounds the tempo (removes decimals). If ‘tempo-sync’ is selected, setting a tempo here will cause FL Studio to stretch/pitch-shift the sample according to this value when loaded. Tempo (BPM) – Sets the tempo in Beats Per Minute.
