ComfyUI Node: Audio Stereo Merge

Audio Stereo Merge:

SaltAudioStereoMerge is a powerful node designed to combine two mono audio tracks into a single stereo audio file. This node is particularly useful for AI artists who want to create immersive audio experiences by merging separate audio channels into a cohesive stereo output. By converting mono tracks to stereo, you can enhance the depth and spatial quality of your audio projects, making them more engaging and dynamic. The node ensures that both input audio tracks are synchronized in length and properly formatted, providing a seamless and high-quality stereo output.

Audio Stereo Merge Input Parameters:

audio_a

audio_a is the first mono audio track that you want to merge into the stereo output. This parameter accepts audio data in the wav format. The node will process this audio to ensure it is in mono format before merging it with the second audio track. The quality and characteristics of this input will directly affect the left channel of the resulting stereo audio.

audio_b

audio_b is the second mono audio track that you want to merge into the stereo output. Similar to audio_a, this parameter also accepts audio data in the wav format. The node will process this audio to ensure it is in mono format before merging it with the first audio track. The quality and characteristics of this input will directly affect the right channel of the resulting stereo audio.

Audio Stereo Merge Output Parameters:

audio

The audio output is the resulting stereo audio file created by merging audio_a and audio_b. This output is in the wav format and contains two channels: the left channel from audio_a and the right channel from audio_b. The stereo audio output is synchronized in length and properly formatted, providing a high-quality audio experience.

Audio Stereo Merge Usage Tips:

• Ensure that both audio_a and audio_b are in mono format before inputting them into the node to avoid any unexpected results.
• Use high-quality mono audio tracks for both inputs to achieve the best stereo output quality.
• If the input audio tracks are of different lengths, the node will automatically trim the longer track to match the length of the shorter one, ensuring synchronization.

Audio Stereo Merge Common Errors and Solutions:

"Input audio must be in mono format."

• Explanation: This error occurs if either audio_a or audio_b is not in mono format.
• Solution: Ensure that both input audio tracks are in mono format before using the node. You can use audio editing software to convert stereo tracks to mono if necessary.

"Invalid audio format."

• Explanation: This error occurs if the input audio files are not in the wav format.
• Solution: Convert your audio files to the wav format before inputting them into the node. Most audio editing software can perform this conversion.

"Audio files are too short."

• Explanation: This error occurs if the input audio files are too short to be processed.
• Solution: Ensure that both input audio files have sufficient length for the desired output. If necessary, extend the audio tracks using audio editing software.
