ComfyUI Node: Audio Playback Rate

Audio Playback Rate:

The SaltAudioPlaybackRate node is designed to adjust the playback speed of an audio file. This can be particularly useful for various audio processing tasks, such as creating time-lapse audio effects, synchronizing audio with video at different speeds, or simply experimenting with different playback rates for creative purposes. By modifying the speed factor, you can either speed up or slow down the audio, which can lead to interesting and unique auditory experiences. This node ensures that the audio quality is maintained while the playback rate is adjusted, making it a valuable tool for AI artists looking to manipulate audio in innovative ways.

Audio Playback Rate Input Parameters:

audio

This parameter accepts the audio file that you want to process. The audio should be in a format that the node can read and manipulate, typically a WAV file. The audio file serves as the base material upon which the playback rate adjustments will be applied.

speed_factor

The speed_factor parameter determines the rate at which the audio will be played back. It is a floating-point value that can range from 0.5 to 12.0, with a default value of 1.0. A value less than 1.0 will slow down the audio, while a value greater than 1.0 will speed it up. For example, a speed_factor of 0.5 will play the audio at half its original speed, and a speed_factor of 2.0 will play it at double the speed. The step value of 0.01 allows for fine-grained control over the playback rate.

Audio Playback Rate Output Parameters:

audio

The output is the processed audio file with the adjusted playback rate. This audio retains the original quality but is played back at the speed specified by the speed_factor parameter. The output can be used in further audio processing tasks or directly in multimedia projects.

Audio Playback Rate Usage Tips:

• Experiment with different speed_factor values to create unique audio effects. For instance, slowing down a fast-paced track can reveal hidden details and nuances.
• Use this node to synchronize audio with video content that has been sped up or slowed down, ensuring that the audio matches the visual pacing.
• Combine this node with other audio processing nodes, such as reverb or echo, to enhance the creative possibilities of your audio projects.

Audio Playback Rate Common Errors and Solutions:

"Invalid audio format"

• Explanation: The input audio file is not in a supported format.
• Solution: Ensure that the audio file is in WAV format before processing it with this node.

"Speed factor out of range"

• Explanation: The speed_factor value provided is outside the acceptable range of 0.5 to 12.0.
• Solution: Adjust the speed_factor to be within the specified range.

"Audio processing failed"

• Explanation: An error occurred during the audio processing, possibly due to corrupted audio data or an internal processing issue.
• Solution: Verify the integrity of the input audio file and try processing it again. If the issue persists, consider using a different audio file.
