Audio Reverse

This effect empowers you to just play the audio file you have highlighted in reverse and, does not contain any controls associated with it.

This effect allows you to pan the sound from left to right. You do this within the stereo field of the project. Properties of the effect can be adjusted from the Control Panel once the effect is added onto the timeline. By default, it's set to zero indicating an evenly distributed sound on both channels. Setting to a negative value will pan the audio to the left channel, whilst the positive value will pan the audio to the right channel.


This effect replicates the sound effects to large venues such as cathedrals.

  • Gain - This option enables you to have adjusted the volume of the signal that is being processed.

Channel Levels

By adding this effect to the audio file makes it possible to independently adjust the overall volume of the right and left audio channels.

how to make audio effect

  • Left - Allows you to establish the level of the volume on the dB scale of the left audio channel. Default source volume is set at 0.0 dB.
  • Right - Allows you to establish the level of the volume on the dB scale of the right audio channel. Default source volume is set at 0.0 dB.


At times audio can be declared useless when the difference between the loudest and quietest points is large enough. The remedy to this problem is the compressor audio effect which scales down the peaks in the audio whilst maintaining the quietest sections be loud enough making it feasible to be normally perceived and, with the same magnitude makes the faint sounds louder under acceptable levels.

  • Input Gain - Gives you the liberty to regulate extent at which the Compressor effect will affect the source audio.
  • Threshold - Enables you to specify extreme levels above unto which audio will be compressed and not compressed respectively.
  • Limiter - This option allows aligning the peaks to a constant level which cannot be surpassed. The use of this option should be regulated since its overuse will cause sound distortions.
  • Ratio (x:1) - Allows specifying the ratio at which audio levels will be scaled down if they go beyond the defined Threshold.
  • Knee - Empowers to wholly manage the compression process. High Knee values make the transition seamless while lower Knee values create a hard knee or a harsh transition at the threshold.
  • Attack Time - Defines the number in milliseconds unto which audio is compressed after it goes beyond the Threshold level by the effect. Raising the attack time makes it possible for the extreme peaks to be detected and compressed momentarily.
  • Release Time - Specifies the number in milliseconds the effect requires to end reducing the audio level after the original level attains a level below the threshold.
  • Output Gain - Gives you the liberty to specify the audio volume after the audio compression process.


Applying this effect inputs echoes to the audio file. By accessing the Control Panel of the effects properties you can either select the number of echoes or how far removed them are from the source audio.

  • Delay - Allows you to determine the number in milliseconds on which the echo is to be removed from the source audio. In a case where the Number of Echoes is greater than 1, the Delay option determines its frequency between two echoes.
  • Falloff - Defines the speed at which each volume echo is being reduced. For instance, at the default rate of 50%, the first echo is going to the served with a half of the original’s audio volume, whilst the second will be halved from the first echo which is now 25% of the source audio’s volume.
  • Number of Echoes - Shows the number of times on which the echo of the original audio is going to be repeated. Repletion number won’t be larger than twenty.


This effect is essential while curating the audio file because it involves adjusting the power of certain frequencies. Adjusting the said frequencies is dependent on the project you are working on and effect you are planning to achieve. Besides, multiple presets comes with the equalizer effect including Bass Boost or Low Pass and on leveraging on them aid in optimizing the effect faster. Also, on the contrary, you might adjust the values of the effect properties to customize them.

You can adjust the volume of the audio record by using the Master Gain feature. Moreover, the Volume feature which can be varied directly from the timeline or the properties menu helps manage the overall volume of the audio file. Therefore, in this regard, the Master Gain should only be utilized to specify the base volume of a clip.

More often than not, those audio files uploaded into a project exhibit a low gain and you are supposed to monitor the default gain which can be seen from the software’s audio meter so that you can manage and conform to standards used in contemporary playback equipment. Keep on changing the Master Gain level each time you notice the file has peaked. For instance, if you find the dialogue file which peaks at -18dB being quiet, raise the Master gain to 9dB. By doing so the overall gain value would be up by -9dB making the audio more audible while still giving space for further volume adjustments if its of help.

Large Room

This effect brings the ambient reverb of a large room. The reverb created in the Large Room lasts longer than the one created by the Medium Room effect.

  • Gain - Gives you the liberty to manage the audio signal that is being processed.

Medium Room

This effect brings ambient reverb of a medium-sized room.

  • Gain - Gives you the liberty to manage the audio signal that is being processed.

Noise Reduction

It is common to have an audio file which contains background noise in which it affects the audio file accordingly. However, this effect is a remedy which helps lower the noise levels if not to remove completely in audio files you are working on.

To use Noise Reduction feature, add the feature on to the timeline and place the playhead at exactly the point you want to get rid of the unwanted sound. Other interfering noises will affect the effectiveness of the effect accordingly. To increase the chances of the effect effectiveness, therefore, capture the atmospheric condition of the required locale either room or filming location before recording the dialogue.

Upon placing the playhead at the targeted location, continue by clicking on the Capture Noise Print button found on the Noise Reduction settings on the effects menu under the Control Panel. At this point, the software will automatically sample the project to be able to detect and remove the noise.

  • Capture Noise Print - Immediately upon hitting this button, the audio from the current playhead's location will be recorded. The Noise Print is what the effect will use to treat the audio file from that specific part and all other spots on the project.

Detailed Noise Reduction options will be visible on the screen once the Noise Print is recorded by the software. Apart from the automatic remedy to clear unwanted sounds, you can as well use the following options and alter the noise reduction process.

  • Reset Noise Print - Resets the immediate Noise Print and permits repositioning of the playhead on the timeline.
  • Add to Noise Print - This option allows you to simultaneously select multiple different spots on the timeline with noises and adds them to the Noise Print.
  • Threshold Level - In a scenario where the noise is aligned with the dialogue it will be fatal if you decide to remove the noise. By default, the Threshold level is 100% implying that all the noise detected by the software will be removed. However, you can still get a more natural sound by lowering the Threshold level.
  • Reduce By - Lets you set decibels rate on which the sound will be reduced. Setting on the higher values will erase the noise while lowering value will bring out a natural dialogue after the noise reduction process.


This effect, when added on the audio file, will cushion the pitch change which usually comes up when you change the playback speed. Pitch effect can help you also to come up with high and low pitched sounds.

  • Semitone Shift - Dragging the effect slider will alter the pitch level accordingly. By default, it's set at zero. The negative value will result in low-pitched sound while the positive value will result to high-pitched sound.

Small Room

Small Room effect reproduces the ambient effect of a small room; however, recreated reverb is shorter than the reverb generated by the Medium Room effect.

  • Gain - Gives you the power to manage the audio signal volume which is being processed.


This effect allows you to add ringing phone sound on the soundtrack of your video.

  • Gain - Gives you the power to manage the audio signal volume which is being processed.

This effect makes it possible for you to maintain a continuous tone and a constant frequency on your project on the timeline. There are several tones to choose from on the Preset menu, whilst you select either Sine or Square from the Type feature. If you keep on increasing tone frequency makes it increasingly difficult to discern between Sine and Square types.
