ComfyUI Node: 监听音频(listen_audio)

监听音频(listen_audio):

The listen_audio node is designed to facilitate audio recording by listening for a specific key press to start and stop the recording process. This node is particularly useful for AI artists who need to capture audio inputs seamlessly without delving into complex technical setups. By simply pressing a designated key, you can initiate the recording, and upon releasing the key, the recording will automatically stop and save the audio file. This functionality is ideal for capturing spontaneous audio inputs, voice notes, or any other sound that needs to be recorded quickly and efficiently.

监听音频(listen_audio) Input Parameters:

press_key

The press_key parameter specifies which key should be pressed to start and stop the audio recording. This parameter accepts a list of keys including "shift", "space", "ctrl", "alt", and "tab". The default value is "shift". By setting this parameter, you can customize the key that triggers the recording process, making it convenient to use based on your workflow preferences.

监听音频(listen_audio) Output Parameters:

audio

The audio output parameter provides the path to the saved audio file. This parameter returns the full file path where the recorded audio is stored, allowing you to easily access and use the recorded audio in subsequent processes or nodes. The audio file is saved in the WAV format, ensuring high-quality sound capture.

监听音频(listen_audio) Usage Tips:

• Ensure that the key specified in the press_key parameter is not commonly used for other shortcuts to avoid accidental recordings.
• Use a quiet environment to minimize background noise and ensure clear audio recordings.
• Test the recording setup with a short audio clip to verify that the key press and release actions are correctly triggering the start and stop of the recording.

监听音频(listen_audio) Common Errors and Solutions:

"KeyError: 'specified key not recognized'"

• Explanation: This error occurs if the key specified in the press_key parameter is not recognized or supported.
• Solution: Ensure that the key specified is one of the supported keys: "shift", "space", "ctrl", "alt", or "tab".

"FileNotFoundError: 'record directory not found'"

• Explanation: This error occurs if the directory where the audio file is to be saved does not exist.
• Solution: Ensure that the directory specified for saving the audio file exists or modify the code to create the directory if it does not exist.

"PermissionError: 'unable to write to the specified directory'"

• Explanation: This error occurs if the program does not have the necessary permissions to write to the specified directory.
