ComfyUI Node: Audio Frequency Boost

Audio Frequency Boost:

SaltAudioFrequencyBoost is a powerful node designed to enhance specific frequencies within an audio file. This node is particularly useful for audio engineers and AI artists who want to emphasize certain frequency ranges in their audio projects, such as boosting the bass or treble to achieve a desired sound effect. By using this node, you can precisely control the frequency, bandwidth, and gain to tailor the audio output to your specific needs. The main goal of SaltAudioFrequencyBoost is to provide a simple yet effective way to modify the frequency characteristics of an audio file, making it an essential tool for audio processing and sound design.

Audio Frequency Boost Input Parameters:

audio

This parameter accepts the audio data that you want to process. The audio should be in a format that can be read and written as a .wav file. This is the primary input on which the frequency boost will be applied.

frequency

This parameter specifies the center frequency that you want to boost. It determines the specific frequency range that will be enhanced. The value is measured in Hertz (Hz), and you can set it to target any frequency within the audio spectrum.

bandwidth

This parameter defines the width of the frequency band around the center frequency that will be affected. A wider bandwidth will affect a larger range of frequencies, while a narrower bandwidth will target a more specific range. The bandwidth is crucial for controlling the precision of the frequency boost.

gain_dB

This parameter sets the amount of gain to be applied to the specified frequency band. The gain is measured in decibels (dB), and it determines how much the selected frequency range will be amplified. Higher gain values will result in a more pronounced boost.

Audio Frequency Boost Output Parameters:

audio

The output parameter is the modified audio data with the specified frequency boost applied. This audio file will have the enhanced frequency characteristics as defined by the input parameters, providing a tailored sound effect based on your settings.

Audio Frequency Boost Usage Tips:

• To achieve a subtle enhancement, use a lower gain_dB value and a narrower bandwidth.
• For a more dramatic effect, increase the gain_dB and consider using a wider bandwidth to affect a larger range of frequencies.
• Experiment with different center frequencies to find the sweet spot that best enhances your audio project.

Audio Frequency Boost Common Errors and Solutions:

Failed to apply frequency boost with FFmpeg

• Explanation: This error occurs when the FFmpeg command fails to execute properly, possibly due to incorrect input parameters or issues with the FFmpeg installation.
• Solution: Ensure that the input parameters (frequency, bandwidth, gain_dB) are within valid ranges and correctly formatted. Verify that FFmpeg is installed and accessible from your system's PATH. If the problem persists, check the error logs for more detailed information and adjust the parameters accordingly.
