Claim:
1. A method implemented in an editing device for previewing an audio effect, comprising: retrieving, by the editing device, audio content; obtaining from a user via a user interface an effect to be applied to an audio segment of the audio content; determining a target number of samples of the audio segment based on the obtained effect, wherein the target number of samples varies with an effect type of the obtained effect; identifying a maximum amplitude and a minimum amplitude within the audio segment; determining a first temporal window of a predetermined size centered about the maximum amplitude and a second temporal window of the predetermined size centered about the minimum amplitude; obtaining a target number of samples from the first temporal window and the second temporal window within the audio segment; obtaining the audio segment and a corresponding time period in which to apply the effect from the user via the user interface, wherein the target number of samples of the audio segment is obtained within the time period; applying the effect to the target number of samples obtained within each of the first temporal window and the second temporal window; and displaying on the user interface, a graphical representation of the first temporal window and the second temporal window having the obtained target number of samples with the applied effect for the user to preview, wherein the graphical representation depicts amplitude varying as a function of time, wherein displaying the graphical representation is performed prior to generating an audio output file with the effect applied to the audio content.
