ComfyUI Node: Audio Simple Echo

Audio Simple Echo:

SaltAudioSimpleEcho is a versatile audio processing node designed to add an echo effect to your audio files. This node allows you to create a series of echoes with customizable delay, decay, and repetition settings, enhancing the depth and texture of your audio. By applying this effect, you can simulate environments such as large halls or canyons, giving your audio a more immersive and dynamic quality. The main goal of this node is to provide an easy-to-use yet powerful tool for adding echo effects, making it ideal for AI artists looking to enrich their audio projects with professional-sounding reverberations.

Audio Simple Echo Input Parameters:

audio

This parameter accepts the audio file you want to process. The audio should be in a compatible format, such as WAV, to ensure proper processing.

times

This integer parameter determines the number of echo repetitions. Increasing this value will result in more echoes. The minimum value is 1, the maximum is 10, and the default is set to 3. Adjusting this parameter allows you to control the density of the echo effect.

delay_ms

This integer parameter specifies the delay between each echo in milliseconds. The minimum value is 100 ms, the maximum is 2000 ms, and the default is set to 100 ms. This setting helps you control the spacing between echoes, which can significantly affect the perceived size of the simulated space.

decay_factor

This float parameter controls the decay rate of the echo. A higher decay factor will result in echoes that fade out more slowly, while a lower decay factor will make them fade out more quickly. The minimum value is 0.1, the maximum is 0.9, and the default is set to 0.4. This parameter is crucial for achieving a natural-sounding echo effect.

Audio Simple Echo Output Parameters:

audio

The output is the processed audio file with the applied echo effect. This audio retains the original format and quality but now includes the specified echo characteristics, making it richer and more dynamic.

Audio Simple Echo Usage Tips:

• Experiment with the times parameter to find the right number of echoes for your project. Fewer echoes can create a subtle effect, while more echoes can make the audio sound more dramatic.
• Adjust the delay_ms parameter to simulate different environments. Shorter delays can mimic small rooms, while longer delays can simulate large open spaces.
• Use the decay_factor to fine-tune the echo's fade-out. A higher decay factor can create a more lingering echo, which is useful for creating atmospheric effects.

Audio Simple Echo Common Errors and Solutions:

"Invalid audio format"

• Explanation: The input audio file is not in a supported format.
• Solution: Ensure that your audio file is in WAV format before processing.

"Parameter out of range"

• Explanation: One of the input parameters is set outside its allowed range.
• Solution: Check the values of times, delay_ms, and decay_factor to ensure they are within the specified limits.

"Processing error"

• Explanation: An unexpected error occurred during the echo application process.
• Solution: Verify that the input audio file is not corrupted and that all parameters are set correctly. If the problem persists, try using a different audio file or adjusting the parameters incrementally.
