Create Echo Effect in Kdenlive Using Delay
This guide demonstrates how to use the built-in “Delay” audio effect in the Kdenlive video editor to create a realistic echo effect for your voice clips. You will learn how to locate the effect, apply it to your audio track, and adjust its key parameters—such as delay time and feedback—to achieve the exact depth and repetition your project requires.
Step 1: Add Your Voice Clip to the Timeline
First, import your voice recording into Kdenlive and drag the audio clip onto an audio track in your timeline. Ensure the clip is selected before proceeding to the next step.
Step 2: Locate the Delay Effect
Navigate to the Effects tab (usually located in the bottom-left or top-left panel of the default workspace). If you cannot see it, enable it by going to View > Effects in the top menu. In the search bar of the Effects panel, type “Delay”. You will find the effect under the “Audio” category.
Step 3: Apply the Effect to the Clip
Click and drag the Delay effect from the list and drop it directly onto your voice clip in the timeline. Once applied, select the audio clip to open its properties in the Effect/Composition Stack panel.
Step 4: Configure the Delay Settings
To create a convincing echo, you need to adjust the parameters in the Effect Stack. The most important settings to configure are:
- Delay (ms): This controls the time gap between the original voice and the first echo. For a standard voice echo, set this between 200 ms and 500 ms. Lower values create a “slapback” room reflection, while higher values create distinct, spaced-out echoes.
- Feedback (%): This determines how many times the echo repeats. A setting of 0% will result in only one echo. Setting it between 20% and 40% will create a fading trail of multiple echoes. Avoid setting this too high (above 70%), as it can cause a runaway feedback loop that distorts the audio.
- Mix / Wet Level: This adjusts the volume balance between the original voice (Dry) and the echo effect (Wet). For a natural sound, keep the original voice loud and set the echo mix to around 30% to 50%.
Step 5: Preview and Fine-Tune
Play back your timeline to hear the effect. If the echo cuts off abruptly at the end of the voice clip, you may need to extend the audio track container or add a silent gap after the clip to allow the delay trail to fade out naturally. Make minor adjustments to the delay time and feedback until the voice matches the virtual environment you want to simulate.
