ComfyUI Node: Music - Equalize

Music - Equalize:

The Music_Equalize node is designed to enhance your audio tracks by applying a parametric equalizer (EQ) to adjust the balance between different frequency components. This node allows you to fine-tune the audio by boosting or cutting specific frequency ranges, such as bass, midrange, and treble, to achieve the desired tonal balance. By using this node, you can improve the clarity and presence of your audio, making it sound more polished and professional. The main goal of the Music_Equalize node is to provide you with a flexible tool to shape the sound of your music, ensuring that each element of your track is heard clearly and harmoniously.

Music - Equalize Input Parameters:

audio

The audio parameter is a dictionary that contains the audio data to be processed. It serves as the input for the equalization process, where the audio is converted into a format suitable for applying EQ adjustments. This parameter is essential as it provides the raw audio that will be enhanced by the node.

bass_freq

The bass_freq parameter specifies the center frequency for the bass range in the audio. It determines which part of the low-frequency spectrum will be affected by the bass gain adjustment. This parameter allows you to target specific bass frequencies to enhance or reduce, providing control over the depth and warmth of the audio. The value is typically set in Hertz (Hz).

bass_gain

The bass_gain parameter controls the amount of gain applied to the bass frequency range, measured in decibels (dB). It allows you to increase or decrease the volume of the bass frequencies, affecting the overall balance and impact of the low end in the audio. The gain can be adjusted within a range, typically from -12.0 dB to 12.0 dB, with a default value that suits most audio tracks.

mid_freq

The mid_freq parameter defines the center frequency for the midrange in the audio. It determines which part of the mid-frequency spectrum will be affected by the mid gain adjustment. This parameter is crucial for shaping the body and presence of the audio, allowing you to emphasize or attenuate specific midrange frequencies. The value is typically set in Hertz (Hz).

mid_gain

The mid_gain parameter controls the amount of gain applied to the midrange frequency range, measured in decibels (dB). It allows you to adjust the volume of the midrange frequencies, impacting the clarity and definition of the audio. The gain can be adjusted within a range, typically from -12.0 dB to 12.0 dB, with a default value that suits most audio tracks.

treble_freq

The treble_freq parameter specifies the center frequency for the treble range in the audio. It determines which part of the high-frequency spectrum will be affected by the treble gain adjustment. This parameter is essential for enhancing the brightness and detail of the audio, allowing you to target specific treble frequencies for adjustment. The value is typically set in Hertz (Hz).

treble_gain

The treble_gain parameter controls the amount of gain applied to the treble frequency range, measured in decibels (dB). It allows you to increase or decrease the volume of the treble frequencies, affecting the overall brightness and airiness of the audio. The gain can be adjusted within a range, typically from -12.0 dB to 12.0 dB, with a default value that suits most audio tracks.

Music - Equalize Output Parameters:

AUDIO

The AUDIO output parameter is a tuple containing the equalized audio data. This output represents the processed audio after the parametric EQ adjustments have been applied. The equalized audio is returned in a format that can be further processed or used in your audio projects. This output is crucial for obtaining the enhanced audio result that reflects the adjustments made to the bass, midrange, and treble frequencies.

Music - Equalize Usage Tips:

• Experiment with different frequency settings for bass_freq, mid_freq, and treble_freq to find the sweet spot for your audio track, enhancing the overall tonal balance.
• Use subtle adjustments in bass_gain, mid_gain, and treble_gain to avoid over-processing the audio, which can lead to distortion or an unnatural sound.

Music - Equalize Common Errors and Solutions:

Error in Music - Equalize: <error_message>

• Explanation: This error occurs when there is an issue during the equalization process, possibly due to incorrect input data or parameter values.
• Solution: Ensure that the audio input is correctly formatted and that all frequency and gain parameters are set within their valid ranges. Double-check the input data and parameter values for any inconsistencies.
