10 tips for ensuring clear and understandable dialogue in your video.

As a video editor, YouTuber or filmmakers, it’s essential that your videos feature clear and understandable dialogue. Poor audio quality can be off-putting to viewers, so you want to ensure that your videos' dialogue is as clear and understandable as possible.

In this blog post, we’ll be going over 10 tips for ensuring clear and understandable dialogue in your video. With these tips, you’ll be able to create content with highly intelligible audio that viewers can enjoy!

Tip #1: Record Dialogue in a Controlled Environment

If you're working on a video production that involves dialogue, one of the most important things you can do to ensure clear and high-quality audio is to record the dialogue in a controlled environment. This means finding a location with minimal background noise, where you can isolate yourself from any potential distractions and focus on capturing clean, clear audio.

Here are a few tips for recording dialogue in a controlled environment:

Find a quiet room or area. The quieter the environment, the easier it will be to capture clean audio. Look for a room or area that is as isolated as possible from external sounds, such as traffic, construction, or other people.
Use soundproofing materials. If you're recording in a space that can't be completely isolated from background noise, you can use soundproofing materials to reduce the amount of ambient noise further. Acoustic foam panels are a popular choice for this purpose, as they can help absorb and reduce unwanted sounds.
Use a microphone with a directional pickup pattern. Some microphones are more sensitive to sounds coming from specific directions than others. A microphone with a directional pickup pattern, such as a cardioid or supercardioid, will be more sensitive to sounds coming from directly in front of the microphone and less sensitive to sounds coming from the sides or rear. This can be helpful for reducing background noise, as it will help to reduce the amount of ambient sound that the microphone picks up.
Use a pop filter. A pop filter can help to reduce plosive sounds (also known as "popping" sounds), which occur when air is expelled from the mouth and hits the microphone. This can be especially important when recording dialogue, as plosive sounds can degrade the overall quality of the audio.

Tip #2: Use High-Quality Microphones

When it comes to recording high-quality dialogue for your video productions, using high-quality microphones is essential. Poor microphone quality can lead to distorted sound and muffled audio, making it difficult for viewers to understand what's being said. To ensure that your audio is crisp and clear, it's a good idea to invest in studio-grade microphones that are specifically designed for capturing dialogue.

Here are a few tips for using high-quality microphones to capture clear and understandable dialogue:

Choose a microphone that is well-suited to your needs. Different microphones are designed to capture sound in different ways, and some are better suited to capturing dialogue than others. Some popular choices for capturing dialogue include dynamic microphones, condenser microphones, and shotgun microphones. Each type of microphone has its own unique set of characteristics, so it's a good idea to do some research and choose a microphone that is well-suited to your specific needs.
Use a microphone with a directional pickup pattern. As mentioned earlier, a microphone with a directional pickup pattern, such as a cardioid or supercardioid, will be more sensitive to sounds coming from directly in front of the microphone and less sensitive to sounds coming from the sides or rear. This can be helpful for reducing background noise and capturing clear dialogue.
Consider using multiple microphones. If you're recording a conversation between multiple people, using multiple microphones can help to capture each person's voice clearly and separately. This can be especially helpful if the people are seated at a distance from each other, as it can help to minimize the impact of background noise and ensure that each person's voice is captured clearly.
Take care of your microphones. Properly maintaining your microphones can help to ensure that they continue to capture high-quality audio. Be sure to handle your microphones gently, as rough handling can cause damage that can impact the audio quality. Additionally, be sure to store your microphones in a safe, dry place when not in use, as moisture and other environmental factors can also affect the audio quality.

Tip #3: Use EQ to Bring Out Specific Frequencies in the Dialogue Audio

Equalization, or "EQ," is a powerful tool for enhancing the clarity and intelligibility of dialogue audio. By manipulating specific frequencies in the audio signal, you can bring out certain aspects of the dialogue, such as the clarity of the vocals or the presence of certain sounds. Here are a few tips for using EQ to bring out specific frequencies in the dialogue audio:

Cut out unnecessary low-end frequencies. Low-end frequencies, such as bass and sub-bass, can sometimes clutter up the mix and make it difficult to hear the dialogue clearly. By using a low-cut filter to cut out these frequencies, you can help to clear up the audio and make the dialogue more intelligible.
Use a high-frequency boost to enhance clarity. High-frequency sounds, such as sibilance and other high-pitched sounds, can sometimes be difficult to hear in the mix. By boosting the high frequencies with an EQ boost, you can help to make these sounds more prominent and easier to hear, enhancing the overall clarity of the dialogue audio.
Use EQ to balance the frequency spectrum. If certain frequencies are too prominent in the audio, they can drown out other frequencies and make the dialogue sound unbalanced. By using EQ to balance the frequency spectrum, you can help to ensure that all frequencies are present in the mix in appropriate amounts, resulting in a more natural and balanced sound. This can be especially helpful if you are dealing with audio that has a lot of background noise or other distracting sounds, as it can help to bring out the dialogue and make it more audible.
Experiment with different EQ settings. Different EQ settings will produce different results, so it's a good idea to experiment with a few different options to see what works best for your audio. Don't be afraid to try out different EQ curves and settings to see what works best for your needs. Just be sure to make any EQ adjustments carefully and in small increments, as making large changes can have a dramatic impact on the audio.

Tip #4: Use Compression to Even Out Volume Levels

Compression is a powerful tool that can be used to improve the overall consistency and clarity of dialogue audio. It works by reducing the dynamic range of the audio, which means that it reduces the volume difference between the loudest and quietest parts of the audio. This can be especially helpful when dealing with conversations between two or more people, as it helps to keep the overall volume level balanced and prevents any one person's voice from dominating the mix.

Here are a few tips for using compression to even out volume levels in dialogue audio:

Use a compressor with moderate ratio and threshold settings. The ratio and threshold settings on a compressor determine how much the audio signal is compressed. A moderate ratio (such as 2:1 or 3:1) and threshold setting will allow the compressor to reduce the dynamic range of the audio, but will still allow the audio to retain some of its natural dynamic range.
Experiment with different compressor settings. Different compressor settings will produce different results, so it's a good idea to experiment with a few different options to see what works best for your audio. Try adjusting the threshold, ratio, attack, and release settings to see how they affect the audio.
Use compression in combination with other techniques. While compression can be a powerful tool for improving the consistency and clarity of dialogue audio, it's not the only way to achieve great results. Try combining compression with other techniques, such as EQ and de-essing, to further enhance the audio.
Don't overdo it. While compression can be a useful tool for improving the clarity of dialogue audio, it's important not to overdo it. Too much compression can result in audio that sounds unnatural and overly processed, so be sure to use it sparingly and adjust the settings carefully.

Tip #5: Use De-essing to Reduce Sibilance

Sibilance is a common issue that can arise when recording dialogue, particularly for female voices. This happens when certain consonant sounds, such as "s," "sh," and "f," are overly emphasized in the mix, resulting in audio that is harsh and difficult to understand. To reduce sibilance and make dialogue more intelligible, you can use a de-esser plugin.

A de-esser is a tool that is specifically designed to reduce sibilance in audio recordings. It works by analyzing the audio signal and attenuating any high-frequency consonant sounds that are causing problems. Here are a few tips for using a de-esser to reduce sibilance in dialogue audio:

Use a de-esser plugin. A de-esser plugin is a software tool that can be used to reduce sibilance in audio recordings. Many digital audio workstations (DAWs) come with de-esser plugins built-in, or you can purchase third-party de-esser plugins from a variety of vendors.
Adjust the threshold and frequency settings. The threshold and frequency settings on a de-esser determine how much the audio signal is attenuated. Adjusting these settings will allow you to fine-tune the de-esser to suit your specific needs. As a general rule, you'll want to set the threshold as low as possible while still reducing the sibilance effectively, and you'll want to set the frequency to match the frequency of the sibilant sounds you are trying to reduce.
Use the de-esser in combination with other techniques. While a de-esser can be a powerful tool for reducing sibilance, it's not the only way to achieve great results. Try combining the de-esser with other techniques, such as EQ and compression, to further enhance the audio.
Don't overdo it. While a de-esser can be a useful tool for reducing sibilance in dialogue audio, it's important not to overdo it. Too much de-essing can result in audio that sounds unnatural and overly processed, so be sure to use it sparingly and adjust the settings carefully.

Tip #6: Use Noise Reduction to Remove Unwanted Background Noise

Even with a quiet recording environment, it's possible that you may still find that there is some background noise present in your dialogue audio. To remove this unwanted noise, you can use a noise reduction plugin. This is a software tool that is specifically designed to remove background hums and other unwanted sounds from audio recordings.

Here are a few tips for using a noise reduction plugin to remove unwanted background noise from your dialogue audio:

Use a noise reduction plugin. A noise reduction plugin is a software tool that can be used to remove unwanted background noise from audio recordings. Many digital audio workstations (DAWs) come with noise reduction plugins built-in, or you can purchase third-party noise reduction plugins from a variety of vendors.
Record a noise profile. To use a noise reduction plugin effectively, you'll need to create a noise profile. This involves recording a short sample of the background noise that you want to remove. The noise reduction plugin will use this sample to create a model of the noise, which it can then use to remove the noise from the rest of the audio.
Adjust the settings as needed. The settings on a noise reduction plugin will allow you to fine-tune the noise reduction process to suit your specific needs. Adjust the threshold, sensitivity, and other settings to achieve the best results.
Use the noise reduction plugin in combination with other techniques. While a noise reduction plugin can be a powerful tool for removing unwanted background noise, it's not the only way to achieve great results. Try combining the noise reduction plugin with other techniques, such as EQ and compression, to further enhance the audio.
Don't overdo it. While a noise reduction plugin can be a useful tool for removing unwanted background noise from dialogue audio, it's important not to overdo it. Too much noise reduction can result in audio that sounds unnatural and overly processed, so be sure to use it sparingly and adjust the settings carefully.

Tip #7: Use Reverb to Add Space to the Dialogue Audio

Reverb is a powerful tool that can be used to add space and depth to your dialogue audio. By adding a subtle amount of reverb, you can give the impression that the conversation is taking place in an acoustic environment, which can make it easier for viewers to follow the conversation. Here are a few tips for using reverb to add space to your dialogue audio:

Use a reverb plugin. A reverb plugin is a software tool that can be used to add reverb to audio recordings. Many digital audio workstations (DAWs) come with reverb plugins built-in, or you can purchase third-party reverb plugins from a variety of vendors.
Choose a reverb preset that matches the desired acoustic environment. Reverb plugins come with a variety of preset reverb settings that are designed to simulate different acoustic environments. Choose a preset that matches the desired acoustic environment for your dialogue audio. For example, if you want to give the impression that the conversation is taking place in a large room, you might choose a preset that simulates the sound of a large concert hall.
Adjust the settings as needed. The settings on a reverb plugin will allow you to fine-tune the reverb to suit your specific needs. Adjust the decay time, damping, and other settings to achieve the desired amount of reverb.
Use reverb in combination with other techniques. While reverb can be a powerful tool for adding space and depth to your dialogue audio, it's not the only way to achieve great results. Try combining reverb with other techniques, such as EQ and compression, to further enhance the audio.
Don't overdo it. While reverb can be a useful tool for adding space and depth to your dialogue audio, it's important not to overdo it. Too much reverb can make the dialogue sound unnatural and difficult to understand, so be sure to use it sparingly and adjust the settings carefully.

Tip #8: Use a pop filter to reduce plosive sounds

As a video editor or audio engineer, you know how important it is to have clear and understandable dialogue in your video productions. One common issue that can hinder the clarity of dialogue is the presence of plosive sounds, also known as "popping" sounds.

These sounds occur when air is expelled from the mouth and hits the microphone, causing a burst of low-frequency energy that can distort the audio signal.

To reduce the impact of plosive sounds on the clarity of your dialogue, it's a good idea to use a pop filter. A pop filter is a simple device that attaches to the front of a microphone and helps to block the flow of air from the mouth, reducing the occurrence of plosive sounds.

Pop filters come in a variety of shapes and sizes, but most consist of a circular frame with a thin, porous material stretched across the center. When a speaker talks into the microphone, the pop filter absorbs the burst of air, reducing the plosive sounds that reach the microphone.

Using a pop filter is a simple and effective way to improve the clarity of your dialogue audio. Here are a few tips for using a pop filter effectively:

Place the pop filter about 6-12 inches in front of the microphone. This will help to minimize the impact of plosive sounds without affecting the overall sound of the dialogue.
Adjust the angle of the pop filter to match the angle of the microphone. If the pop filter is positioned too far away from the microphone, it may not be effective at reducing plosive sounds.
Experiment with different pop filter materials. Some pop filters use a thin, synthetic material, while others use a denser, more porous material. Each type of material can produce slightly different results, so it's a good idea to try a few different options to see which works best for your needs.
Use a pop filter in combination with other techniques. While a pop filter is an effective tool for reducing plosive sounds, it's not the only way to improve the clarity of your dialogue audio. Combining a pop filter with other techniques, such as using a high-quality microphone and applying EQ or compression, can help to further enhance the clarity of your dialogue.

Tip #9: Use a noise gate to reduce background noise

A noise gate is a tool that can be used to reduce background noise in audio recordings. It works by analyzing the audio signal and only allowing audio above a certain threshold to pass through. This can be useful for reducing background noise in dialogue recordings, as it can help to remove low-level noise that might not be audible on its own, but that can still degrade the overall quality of the audio.

To use a noise gate, you'll need a digital audio workstation (DAW) with a noise gate plug-in. To set up the noise gate, you'll need to adjust the threshold level, attack time, and release time. The threshold level determines the point at which the noise gate will start to attenuate the audio signal. The attack time determines how quickly the noise gate will start to attenuate the signal, and the release time determines how quickly the noise gate will stop attenuating the signal.

Using a noise gate can be a useful technique for reducing background noise in dialogue recordings, especially if you don't have access to a quiet recording space. Just be sure to adjust the settings carefully, as setting the threshold level too low can result in the dialogue audio being heavily attenuated, while setting it too high can allow too much background noise to pass through.

In summary, using a noise gate can be a useful technique for reducing background noise in dialogue recordings. By adjusting the threshold level, attack time, and release time carefully, you can help ensure that your dialogue audio is clean and clear, without any unwanted background noise.

Tip #10: Test the audio quality before finalizing the video

One key step in achieving great audio is to test the audio quality before finalizing the video. This is especially important for dialogue, as clear and understandable dialogue is crucial for engaging and communicating with the viewer.

There are several reasons why testing the audio quality of your dialogue is important. First and foremost, it helps ensure that the viewer can easily follow and understand the dialogue.

If the audio quality is poor or the dialogue is difficult to hear, it can be frustrating and even frustrating for the viewer, potentially leading to a loss of engagement. Additionally, testing the audio quality can help you identify and fix any issues before the video is released, ensuring that you are presenting the best possible audio quality to your audience.

So, how can you test the audio quality of your dialogue and make any necessary adjustments? Here are a few tips:

Listen to the audio on different speakers or headphones. Different audio systems will have different frequency responses, so it's a good idea to listen to your audio on a variety of speakers or headphones to get a sense of how it sounds on different systems.
Use a loudness meter to check the overall volume and dynamic range of the audio. A loudness meter can help you ensure that the audio is neither too loud nor too quiet, and that the dynamic range is appropriate for the material.
Check the clarity of the dialogue by listening for issues such as background noise, sibilant sounds, and plosive sounds. If you notice any of these issues, you can use techniques such as EQ, compression, de-essing, and pop filtering to improve the clarity of the audio.
Use volume automation to adjust the volume of the dialogue as needed. If the volume of the dialogue is too low or too high in certain parts of the video, you can use volume automation to adjust the volume as needed to ensure that it is clearly audible.
Get feedback from others. Sometimes, it can be helpful to get a second (or third) set of ears to listen to the audio and give feedback. This can help you identify any issues that you might have missed, and can also give you a sense of how the audio sounds to someone else.

By following these tips, you should be able to create dialogue audio that is clear and intelligible. Remember: even with great audio quality, it’s always essential to ensure that the content of the dialogue is interesting and engaging for viewers. Good luck!
