Audio Effects

The sound is as important as video during the video editing process, and for that reason, FilmoraPro features a wide variety of audio effects that enable you to fine-tune each audio file you decide to include in your video’s soundtrack.

 FilmoraPro Audio Effect

Audio Reverse:

Enables you to play the selected audio clip in reverse. This effect doesn’t have any controls, as it simply plays audio files backward.

Balance:

 FilmoraPro Audio Effect

You can pan the audio from left to right within the stereo field of their projects. Once the effect is added to an audio clip, its properties can be adjusted from the Controls Panel. Choosing a negative value on the Balance slider will pan the audio to the left channel, while positive values pan the audio to the right channel. The default Balance value is set to zero, which means that sounds are equally distributed to both channels.

Cathedral

This audio effect simulates the acoustics of large venues, like cathedrals.

  • Gain – Allows you to control the volume of the audio signal that is being processed.

Channel Levels

The overall volume of left and right audio channels can be adjusted separately by applying the Channel Levels effect.

 FilmoraPro Audio Effect

  • Left - Lets you determine the volume level of the left audio channel on a dB scale. The original source volume is 0.0 dB.
  • Right - Lets you determine the volume level of the right audio channel on a dB scale. The original source volume is 0.0 dB.

Compressor

Sometimes the difference between the loudest and the quietest points in an audio file can be too large which can render the file useless. In these situations, you can use the Compressor effect to reduce the peaks in the audio while keeping the quiet parts loud enough so that they can still be normally perceived, and conversely, you can make faint sounds louder without pushing the peaks above acceptable levels.


 FilmoraPro Audio Effect

  • Input Gain – Enables you to control the amount of the source audio that is affected by the Compressor effect.
  • Threshold – Sets the audio level above which the file will be compressed, and below which the compression won’t affect the audio.
  • Limiter – Allows you to limit the peaks to a constant level which audio peaks cannot exceed. However, the Limiter option shouldn’t be used excessively, because it can cause sound distortions.
  • Ratio (x:1) – This option enables you to set the ratio at which audio levels will be reduced if they exceed the selected Threshold.
  • Knee – Lets you control the transition from uncompressed to compressed audio. Lower values create a hard knee or a harsh transition at the threshold, while higher Knee values make this transition much smoother.
  • Attack Time – Determines how many milliseconds the effect needs to compress the audio after it exceeds the Threshold level. Increasing the attack time ensures that extremes peaks are detected and compressed momentarily.
  • Release Time – Determines how many milliseconds the compressor needs to stop reducing the audio level after source level reaches a value that is below the threshold.
  • Output Gain – Enables you to set the audio volume after the audio compression process.

Echo

Adds echoes to the audio file to which it is applied. You can choose the number of echoes or how far removed they are from the original sound in the effect’s properties that can be accessed from the Control Panel.

 FilmoraPro Audio Effect

  • Delay – This option allows you to control for how many milliseconds an echo is going to be removed from the original sound. If the Number of Echoes value is larger than 1, then the Delay option also determines the amount of time that passes between two echoes.
  • Falloff – Sets the rate at which the volume of each echo is reduced. At the default rate of 50%, the first echo is going to have a half of the source audio’s volume, while the second echo is going to have 25% of the original’s audio volume.
  • Number of Echoes – Displays how many times the echo of the source audio is going to be repeated. The maximum number of repetitions can’t be larger than twenty.

Equalizer

Adjusting the strength of specific frequencies in an audio file is the reason why the Equalizer effect is frequently used during the audio editing process. Which frequency you’re going to highlight depends on the audio file you’re working with and on the effect, you’re trying to achieve. The Equalizer effect also contains a number of presets such as Bass Boost or Low Pass that can help you optimize it faster. However, you can customize each of the available properties by either inserting new values or by dragging the sliders of each of the options that the Equalizer effect provides.

 FilmoraPro Audio Effect

The Master Gain feature enables you to alter the volume of an audio file. The overall volume of a clip can also be controlled by the Volume feature that can be adjusted directly from the timeline or from the Properties menu in the Controls Panel, so the Master Gain should only be utilized to set the base volume of a clip.

The sound files you import into a project often have a low gain, and in order to adjust them in accordance with the standards used on contemporary playback equipment, you should just monitor the default gain displayed by the software’s audio meters. If you notice that the file has peaked at any point, you can then proceed to alter the Master Gain level. If you have a dialogue file that peaks at -18dB and it is too quiet, you should raise the Master Gain to 9dB. This action will increase the overall gain value to -9dB which will make the dialogue more audible while leaving room for further volume adjustments if they are necessary.

Large Room

Applying this effect to an audio file will simulate the ambient reverb of a large room. The reverb you’ll be able to create will last longer than the reverb created by the Medium Room effect.

  • Gain - Allows you to control the volume of the audio signal that is being processed.

Medium Room

The ambient reverb of a medium-sized room will be simulated.

  • Gain - Allows you to control the volume of the audio signal that is being processed.

Noise Reduction

Audio files often contain background noises that can significantly reduce their quality. The Noise Reduction effect offers a quick and easy way to remove or decrease noise levels in audio files you’re using in your projects.

After you add the Noise Reduction effect to an audio file, you placed onto an audio track on the timeline, position the playhead at the exact spot on the timeline where unwanted noise is located. Keep in mind that the existence of other interfering noises will lessen the effect’s capability to reduce the noise that is troubling you. Recording the atmospheric sounds of a room or any other filming location, before you record the dialogue may help you deal with all other noises that may interfere with a noise you’re trying to reduce.

Once you’ve positioned the playhead at the desired location, you should proceed to click on the Capture Noise Print button under the Noise Reduction settings, located in the Effects menu that is available in the Controls Panel. The software will then sample the audio file in order to detect and remove the noise.

 FilmoraPro Audio Effects

  • Capture Noise Print – The audio at the playhead’s current position will be recorded after you click on this button. The Noise Reduction effect will use the Noise Print to erase the noise from that particular spot and all other locations on the audio track.

After the software captures a Noise Print, more Noise Reduction options will appear on the screen. Even though in most cases a noise is removed immediately after capturing the noise print, you may want to use these additional options to tweak the noise reduction process.

  • Reset Noise Print – Resets the current Noise Print and enables you to reposition the playhead on the timeline.
  • Add to Noise Print – This option lets you select several different spots in an audio file that contain noises and adds them to the Noise Print.
  • Threshold Level – In situations when the noise overlaps with dialogues removing the noise completely can produce an unwanted result. The default Threshold Level is 100%, which means that all noise detected by the software will be removed, but slightly reducing this value, will retain small amounts of noise and potentially generate a more natural sounding dialogue.
  • Reduce By – Allows you to choose by how many decibels a noise is going to be reduced. Higher Reduce By values will remove a noise entirely, but lowering this value can make the audio file sound more natural after the noise reduction process.

Pitch

Applying the Pitch effect to an audio file can help you counter the pitch change that occurs after you alter the playback speed. You can also use it to create high and low pitched sounds.

 FilmoraPro Audio Effects

  • Semitone Shift – Dragging the Semitone Shift slider left or right will increase or decrease the pitch level. This option is set to zero by default, and if you assign it a negative value you will get a low-pitched sound while assigning a positive value will create a high pitched sound.

Small Room

This effect recreates the ambient reverb of a small room. The generated reverb is shorter than the reverb produced by the Medium Room effect.

  • Gain - Allows you to control the volume of the audio signal that is being processed.

Telephone

FilmoraPro’s users can add the sound of a telephone ringing to the soundtrack of your video.

  • Gain - Allows you to control the volume of the audio signal that is being processed.

Tone

 FilmoraPro Audio Effects

You can apply a continuous tone at a constant frequency to the audio file you placed on the timeline. The Preset menu offers a number of different tones you can choose from, while the Type feature lets you choose between Sine and Square options. As you increase the tone frequency it becomes progressively more difficult to distinguish between Sine and Square types.
