ComfyUI Node: Music - Audio Upscale

Music - Audio Upscale:

The Music_AudioUpscale node is designed to enhance the quality of audio files by increasing their sample rate, which can lead to improved sound clarity and detail. This node is particularly useful for audio professionals and enthusiasts who wish to upscale audio to a higher sample rate, thereby potentially enhancing the listening experience. The node also offers an optional feature to restore the original frequency after upscaling, providing flexibility in maintaining the original sound characteristics if desired. By utilizing this node, you can achieve a higher fidelity audio output, making it an essential tool for music production and audio editing tasks.

Music - Audio Upscale Input Parameters:

audio

This parameter represents the audio input that you wish to upscale. It is expected to be in a format compatible with the ComfyUI audio dictionary, which typically includes audio data and its associated sample rate. The quality and characteristics of the input audio will directly influence the upscaling process and the resulting output.

target_sample_rate

The target_sample_rate parameter specifies the desired sample rate to which the audio will be upscaled. It accepts integer values ranging from 16,000 to 192,000, with a default value of 48,000. This parameter is crucial as it determines the level of detail and clarity in the upscaled audio. A higher sample rate can capture more audio detail, but it also requires more processing power and storage space.

restore_original_sr

This boolean parameter allows you to decide whether to restore the audio to its original sample rate after the upscaling process. By default, it is set to False, meaning the audio will remain at the upscaled sample rate. Setting this parameter to True will revert the audio back to its original sample rate, which can be useful if you want to maintain the original sound characteristics while still benefiting from the upscaling process.

Music - Audio Upscale Output Parameters:

AUDIO

The output parameter, AUDIO, is the upscaled audio in the form of a ComfyUI audio dictionary. This output retains the enhanced sample rate and any modifications made during the upscaling process. The resulting audio is expected to have improved clarity and detail, making it suitable for high-quality audio applications.

Music - Audio Upscale Usage Tips:

• To achieve the best results, choose a target_sample_rate that matches the intended use of the audio. For example, 48,000 Hz is a common choice for high-quality audio playback.
• If you want to maintain the original sound characteristics while still benefiting from the upscaling process, consider setting restore_original_sr to True.
• Ensure that the input audio is of good quality, as the upscaling process can only enhance existing details and cannot create new information from poor-quality audio.

Music - Audio Upscale Common Errors and Solutions:

Error in Music - Audio Upscale: <error_message>

• Explanation: This error message indicates that an exception occurred during the upscaling process. The specific error message will provide more details about the nature of the problem.
• Solution: Check the input audio format and ensure it is compatible with the ComfyUI audio dictionary. Verify that the target_sample_rate is within the acceptable range and that all parameters are correctly set. If the problem persists, consult the traceback for more detailed debugging information.
