ComfyUI Node: Music - Noise Remove

Music - Noise Remove:

The Music_NoiseRemove node is designed to enhance audio quality by effectively removing unwanted noise from audio tracks. It offers two distinct modes of noise reduction: "Hiss Only" and "Full Denoise." The "Hiss Only" mode targets high-frequency noise, specifically above 8kHz, which is often referred to as hiss or chiados, making it ideal for preserving the integrity of audio effects while cleaning up the sound. On the other hand, the "Full Denoise" mode utilizes a comprehensive noise reduction technique to eliminate a broader range of noise, ensuring a cleaner and more polished audio output. This node is particularly beneficial for audio artists and producers who seek to improve the clarity and quality of their audio recordings without compromising the original sound. By leveraging professional noise reduction methods, the Music_NoiseRemove node provides a reliable solution for enhancing audio tracks, making it an essential tool for anyone working with audio content.

Music - Noise Remove Input Parameters:

audio

The audio parameter is the input audio data that you want to process for noise removal. It is expected to be in a format compatible with the node's processing capabilities, typically as an audio tensor. This parameter is crucial as it serves as the source material from which noise will be removed.

mode

The mode parameter determines the type of noise reduction to be applied. It offers two options: "Hiss Only" and "Full Denoise." "Hiss Only" focuses on removing high-frequency noise above 8kHz, which is useful for maintaining audio effects while cleaning up the sound. "Full Denoise" applies a more comprehensive noise reduction technique to eliminate a wider range of noise. This parameter allows you to choose the level of noise reduction based on your specific needs.

intensity

The intensity parameter controls the strength of the noise reduction process. It is a floating-point value ranging from 0.0 to 1.0, with a default value of 0.5. A higher intensity value results in more aggressive noise reduction, which can be useful for heavily noisy audio, while a lower value preserves more of the original audio characteristics. This parameter allows you to fine-tune the balance between noise reduction and audio fidelity.

Music - Noise Remove Output Parameters:

AUDIO

The AUDIO output parameter is the processed audio data with noise removed. It is returned in the same format as the input audio, ensuring compatibility with subsequent processing or playback. This output represents the cleaned audio, free from unwanted noise, and is the primary result of the node's operation.

Music - Noise Remove Usage Tips:

• For audio tracks with noticeable high-frequency hiss, use the "Hiss Only" mode to effectively clean up the sound while preserving the original audio effects.
• When dealing with audio that has a variety of noise types, opt for the "Full Denoise" mode to achieve a more comprehensive noise reduction.
• Adjust the intensity parameter to find the right balance between noise reduction and audio quality. Start with the default value and increase or decrease as needed based on the level of noise in your audio.

Music - Noise Remove Common Errors and Solutions:

Audio contains NaN/Inf values, skipping

• Explanation: This error occurs when the input audio data contains invalid values such as NaN (Not a Number) or Inf (Infinity), which cannot be processed.
• Solution: Check the input audio for any anomalies or corruption. Ensure that the audio data is correctly formatted and free from invalid values before processing.

Audio too short (<2048 samples), skipping

• Explanation: The input audio is too short for the noise removal process, which requires a minimum of 2048 samples to function effectively.
• Solution: Provide a longer audio clip for processing. If the audio is inherently short, consider concatenating it with silence or other audio to meet the minimum sample requirement.

Noise removal returned None

• Explanation: The noise removal process failed to produce a valid output, possibly due to an internal error or unsuitable input conditions.
• Solution: Verify that the input parameters are correctly set and that the audio data is valid. If the issue persists, try adjusting the mode or intensity settings and reprocess the audio.

Processed audio contains NaN/Inf, returning original

• Explanation: The processed audio contains invalid values, indicating a problem during the noise removal process.
• Solution: Re-evaluate the input audio and parameters. Ensure that the intensity is set within the valid range and that the audio data is suitable for processing. If necessary, try using a different mode or adjusting the intensity.
