ComfyUI Node: MegaTTS3 Speakers Preview

MegaTTS3 Speakers Preview:

The MegaTTS3SpeakersPreview node is designed to facilitate the previewing of speaker audio files within the MegaTTS3 system. This node is particularly useful for users who need to quickly access and listen to specific speaker samples stored in a designated directory. By leveraging this node, you can efficiently load and process audio files, allowing for seamless integration into your text-to-speech workflows. The primary function of this node is to retrieve and prepare audio data for playback, ensuring that you can easily evaluate the quality and characteristics of different speaker voices before proceeding with further processing or synthesis tasks.

MegaTTS3 Speakers Preview Input Parameters:

speaker

The speaker parameter is a string that specifies the name of the speaker audio file you wish to preview. This parameter is crucial as it determines which audio file will be loaded and processed by the node. The input should match the filename of the desired speaker sample stored in the speakers directory. There are no explicit minimum or maximum values for this parameter, but it must correspond to a valid file name within the directory.

MegaTTS3 Speakers Preview Output Parameters:

speaker

The speaker output provides the file path of the speaker audio file that was loaded. This output is useful for confirming the exact file that was processed, ensuring that the correct audio sample was accessed.

AUDIO

The AUDIO output is a dictionary containing the waveform and sample rate of the loaded audio file. The waveform is a tensor representation of the audio data, while the sample rate indicates the number of samples per second. This output is essential for playback and further audio processing, as it provides the necessary data to evaluate the speaker's voice quality and characteristics.

MegaTTS3 Speakers Preview Usage Tips:

• Ensure that the speaker parameter matches the exact filename of the audio file you wish to preview, including the file extension, to avoid errors in loading the file.
• Utilize the AUDIO output to directly play back the audio sample or integrate it into further processing nodes for more complex text-to-speech tasks.
