Remover ruídos do Áudio com plugin nativo do Reaper

Summary

In this detailed tutorial, the presenter demonstrates how to effectively remove unwanted noise from audio recordings using Reaper's native plugin. Starting with the identification of issues like low volume and background noise, the video guides viewers through the process of normalizing audio and applying noise reduction techniques step by step. The presenter also explains how to balance between noise removal and preserving voice quality, offering valuable tips for improving sound clarity. Viewers are encouraged to follow the steps for better audio production, and offered links to related courses and social media for further learning.

Takeaways

• 😀 Make sure to normalize your audio before working on any processing to ensure a better quality output.
• 😀 Always leave a few seconds of silence before recording your main audio to capture ambient noise, which can be used to effectively remove background noise during processing.
• 😀 When using the Reafir plugin to remove noise, adjust the settings carefully to prevent distortion of the voice.
• 😀 The Reafir plugin has an automatic noise detection feature, but it's essential to fine-tune it for the best results, balancing noise removal with preserving voice clarity.
• 😀 Excessive noise reduction can distort the voice, so it's important to find a balance between noise removal and maintaining vocal quality.
• 😀 For optimal noise removal, apply the plugin in multiple stages, processing the audio in layers to reduce noise progressively without damaging the voice.
• 😀 After each stage of noise reduction, render the audio to a new track to compare the results and ensure improvements without over-processing.
• 😀 If the original recording has issues such as low volume or excessive reverberation, these can be addressed during post-production, but perfect results might not always be achievable.
• 😀 The ideal recording environment should be acoustically treated to minimize background noise and reverberation for the best sound quality from the start.
• 😀 Despite using advanced plugins, if the initial recording quality is poor, it may not be possible to achieve perfect clarity, but significant improvements can still be made.

Q & A

What is the main purpose of the tutorial?

The tutorial demonstrates how to remove unwanted noise from an audio recording using the Reaper plugin 'ReaFIR'.

Why is normalizing the audio an important first step?

Normalizing the audio ensures that the volume is increased to a more acceptable level, making it easier to process and apply noise reduction effectively.

What is the 'ReaFIR' plugin used for in this tutorial?

The 'ReaFIR' plugin is used to remove unwanted background noise from the audio, such as hums, static, or other ambient sounds.

Why is it recommended to record a segment of just noise before speaking?

Recording a segment of just ambient noise helps the plugin accurately identify the unwanted noise in the track, allowing for better noise removal results.

What happens if the noise is removed too aggressively using 'ReaFIR'?

If too much noise is removed, the voice may become distorted and unnatural. It's important to balance noise removal with maintaining the voice's quality.

How do you adjust the noise removal settings to avoid distorting the voice?

You can adjust the 'Size' setting in 'ReaFIR' to 1024 for best quality and tweak the noise detection settings to allow for less aggressive noise removal, thus preserving the voice's clarity.

What does the tutorial suggest about recording conditions for better audio quality?

The tutorial suggests that the best results come from recording in a properly treated, quiet environment to minimize unwanted noise from the start.

How does the tutorial recommend comparing the cleaned audio with the original?

The tutorial recommends rendering the cleaned audio in a separate track and comparing it with the original track to assess the effectiveness of the noise removal process.

What are the potential downsides of excessive noise removal in audio?

Excessive noise removal can lead to a loss of audio quality, causing the voice to sound unnatural or hollow. The goal is to reduce noise while retaining the voice's integrity.

Why is it important to repeat the noise removal process multiple times?

Repeating the process allows for more thorough noise removal, as it helps refine the audio, gradually eliminating more noise without over-processing the voice.
