ComfyUI Node: Audio Bass Boost

Audio Bass Boost:

SaltAudioBassBoost is a powerful node designed to enhance the bass frequencies in an audio file, making the low-end sounds more prominent and impactful. This node is particularly useful for audio engineers, music producers, and AI artists who want to add depth and richness to their audio tracks. By applying a low-pass filter and boosting the gain of the filtered frequencies, SaltAudioBassBoost ensures that the bass elements stand out without distorting the overall sound. This can be especially beneficial for genres like electronic music, hip-hop, and any other style that relies heavily on bass. The node is easy to use and integrates seamlessly into your audio processing workflow, allowing you to achieve professional-quality bass enhancement with minimal effort.

Audio Bass Boost Input Parameters:

audio

This parameter accepts the audio file that you want to process. The audio should be in a compatible format such as WAV. The node will read this audio file and apply the bass boost effect to it.

cutoff_freq

This integer parameter sets the cutoff frequency for the low-pass filter. Frequencies below this value will be boosted. The default value is 150 Hz, with a minimum of 20 Hz and a maximum of 300 Hz. Adjusting this value allows you to target different ranges of bass frequencies, depending on the specific needs of your audio track.

boost_dB

This float parameter determines the amount of gain to apply to the bass frequencies. The default value is 5.0 dB, with a minimum of 0.0 dB and a maximum of 24.0 dB. Increasing this value will make the bass frequencies more prominent, while decreasing it will result in a subtler effect.

Audio Bass Boost Output Parameters:

audio

The output is the processed audio file with the bass frequencies boosted according to the specified parameters. This enhanced audio can be used in further processing or as a final product, providing a richer and more impactful listening experience.

Audio Bass Boost Usage Tips:

• For a subtle bass enhancement, start with a lower boost_dB value, such as 2.0 or 3.0 dB, and gradually increase it until you achieve the desired effect.
• Experiment with different cutoff_freq values to find the sweet spot for your specific audio track. Lower values will affect deeper bass frequencies, while higher values will target upper bass and lower midrange frequencies.
• Use this node in combination with other audio processing nodes, such as normalization or compression, to achieve a balanced and polished final product.

Audio Bass Boost Common Errors and Solutions:

"Failed to read audio file"

• Explanation: This error occurs when the input audio file is not in a compatible format or is corrupted.
• Solution: Ensure that the audio file is in a supported format like WAV and is not corrupted. Try re-exporting the audio file from your audio editing software.

"Cutoff frequency out of range"

• Explanation: This error occurs when the cutoff_freq parameter is set outside the allowed range of 20 to 300 Hz.
• Solution: Adjust the cutoff_freq parameter to be within the specified range.

"Boost dB out of range"

• Explanation: This error occurs when the boost_dB parameter is set outside the allowed range of 0.0 to 24.0 dB.
• Solution: Adjust the boost_dB parameter to be within the specified range.
