In CyberLink AudioDirector you can add an echo to your audio, by adding a series of delayed and decaying sources of the original audio to it.
To add a chorus effect to audio, do this:
1. | Select the media file in the library that you want to apply the phase effect to. |
2. | If required, use range selection to select the portion of audio you want to apply the effect to. See Range Selection for more information on selecting a range of an audio file. If you don't select a range, the effect is applied to the entire audio clip. |

|
Note: the entire audio file's waveform is selected by default when this feature is opened. If you want to apply this feature to the entire audio file, you do not need to use range selection when the entire waveform is selected.
|
3. | Decide whether you want to apply the effect on all the available channels, or just one channel. See Selecting Channels for Editing for more information on selecting channels. |
4. | Click Echo under the Apply Effect section. |
5. | In the window that displays, select the echo preset from the Presets drop-down. Select the preset that best suits the sound you want to achieve. |
6. | If required, click to modify the advanced settings as follows: |
• | Initial delay time: use this slider to set how far behind, in milliseconds, the audio with the echo effect applied will start behind the original audio signal. |
• | Feedback: use this slider to set the ratio that determines how long the echoed sound will last. Dragging the slider left produces less of an echo, while dragging it right can produce an echo that never seems to fade out. |
• | Equalizer: use these sliders to adjust the room characteristics where the audio is being reflected to create the echo. More reflective surfaces create a brighter sound, while a room with absorbent walls creates an echo that is a lot darker. |
7. | If required, you can preview how the applied effect will sound by selecting Adjusted result and then clicking the play button on the playback controls. Select Original audio if you want to play the original audio. |
8. | Click Apply to add the echo effect to the audio. |

|
Note: if required, click on the Effect tab to see the applied effect in the edit panel. See Effect Tab for more information.
