AudioCombine Description

Merge two audio inputs creatively using mathematical operations for unique soundscapes and effects, ensuring synchronized lengths and sample rates.

AudioCombine:

The AudioCombine node is designed to merge two audio inputs into a single output using various mathematical operations. This node is particularly useful for AI artists who want to blend different audio tracks creatively. By combining audio waveforms through addition, subtraction, multiplication, division, or averaging, you can achieve unique soundscapes and effects. The node ensures that the sample rates of the input audios are matched and that the lengths of the audio tracks are synchronized, providing a seamless and harmonious output. This functionality is essential for creating complex audio compositions and enhancing the auditory experience in multimedia projects.

AudioCombine Input Parameters:

audio_1

audio_1 is the first audio input that you want to combine. It should be provided in the form of an AUDIO type, which includes both the waveform and the sample rate. This parameter is required and serves as one of the primary sources for the combination process.

audio_2

audio_2 is the second audio input that you want to combine. Similar to audio_1, it should be provided as an AUDIO type, containing the waveform and the sample rate. This parameter is also required and acts as the secondary source for the combination.

method

method specifies the mathematical operation used to combine the two audio inputs. The available options are add, mean, subtract, multiply, and divide. The default value is add. This parameter determines how the waveforms of audio_1 and audio_2 will be merged, allowing you to create different audio effects based on the chosen method.

AudioCombine Output Parameters:

AUDIO

The output is an AUDIO type that contains the combined waveform and the sample rate. This output represents the result of merging audio_1 and audio_2 using the specified method. The combined audio can be used in further processing or directly in your multimedia projects.

AudioCombine Usage Tips:

  • To create a balanced mix of two audio tracks, use the mean method, which averages the waveforms of the inputs.
  • If you want to emphasize the differences between two audio tracks, the subtract method can highlight the unique elements of each input.
  • For creating complex soundscapes, experiment with the multiply and divide methods to achieve unique audio effects.
  • Ensure that the sample rates of your input audios are compatible or let the node handle the resampling to avoid any synchronization issues.

AudioCombine Common Errors and Solutions:

"Sample rates do not match"

  • Explanation: The sample rates of audio_1 and audio_2 are different, and the node needs to resample one of the inputs.
  • Solution: The node automatically resamples the audio with the lower sample rate to match the higher sample rate. Ensure that your inputs are correctly formatted and let the node handle the resampling.

"Audio lengths do not match"

  • Explanation: The lengths of audio_1 and audio_2 are different, which can cause issues in the combination process.
  • Solution: The node trims the longer audio to match the length of the shorter one. Ensure that your inputs are correctly formatted and let the node handle the synchronization.

"Invalid method specified"

  • Explanation: The method parameter contains a value that is not one of the allowed options (add, mean, subtract, multiply, divide).
  • Solution: Ensure that the method parameter is set to one of the valid options. If you are unsure, use the default value add.
