ComfyUI Node: AudioCrop

AudioCrop:

The AudioCrop node is designed to help you extract specific segments from an audio file by defining start and end times. This is particularly useful when you need to isolate a portion of an audio track for further processing or analysis. By specifying the start and end times, you can precisely control which part of the audio waveform is retained, making it easier to work with only the relevant sections. This node is essential for tasks that require focused audio manipulation, such as creating samples, removing unwanted sections, or preparing audio for synchronization with other media.

AudioCrop Input Parameters:

audio

This parameter represents the audio data that you want to crop. It should be provided in a format that includes both the waveform and the sample rate. The waveform is a tensor that contains the audio signal, while the sample rate indicates the number of samples per second. This input is crucial as it forms the basis of the cropping operation.

start_time

The start_time parameter specifies the beginning of the audio segment you want to extract. It can be provided in the format "MM:SS" (minutes and seconds) or as a number of seconds if no colon is included. The default value is "0:00", meaning the cropping will start from the very beginning of the audio. This parameter allows you to pinpoint the exact starting point of the desired audio segment.

end_time

The end_time parameter defines the end of the audio segment you wish to extract. Similar to start_time, it can be provided in the format "MM:SS" or as a number of seconds. The default value is "1:00", which means the cropping will end at the one-minute mark. This parameter is essential for determining the endpoint of the audio segment, ensuring that only the desired portion is retained.

AudioCrop Output Parameters:

audio

The output of the AudioCrop node is the cropped audio segment. This output retains the same structure as the input audio, including the waveform and sample rate, but only includes the portion of the audio that falls within the specified start and end times. This allows you to work with a focused segment of the audio, making subsequent processing or analysis more efficient and manageable.

AudioCrop Usage Tips:

• Ensure that the start_time and end_time parameters are within the duration of the audio file to avoid errors.
• Use the "MM:SS" format for more precise time specification, especially for longer audio files.
• If you need to crop multiple segments from the same audio file, consider using multiple instances of the AudioCrop node with different start and end times.

AudioCrop Common Errors and Solutions:

AudioCrop: Start time must be less than end time and be within the audio length.

• Explanation: This error occurs when the specified start_time is greater than or equal to the end_time, or if either time is outside the duration of the audio file.
• Solution: Double-check the start_time and end_time values to ensure that the start time is less than the end time and both times are within the audio file's duration. Adjust the times accordingly to resolve the error.
