Audio Repeat

Documentation

Class name: SaltAudioRepeat
Category: SALT/Audio/Process
Output node: False

The SaltAudioRepeat node is designed to repeat an audio clip a specified number of times. This functionality is useful for extending the duration of an audio segment without altering its original content.

Input types

Required

audio
- The 'audio' parameter is the raw audio data to be processed. It serves as the base audio clip that will be repeated according to the 'repeat_times' parameter.
- Comfy dtype: AUDIO
- Python dtype: bytes
repeat_times
- The 'repeat_times' parameter specifies how many times the audio clip should be repeated. This directly influences the length of the resulting audio output.
- Comfy dtype: INT
- Python dtype: int

Output types

audio
- Comfy dtype: AUDIO
- The output is the audio data after being repeated the specified number of times, effectively extending its duration.
- Python dtype: bytes
