Node: Audio Recorder @ vrch.ai (vrch.ai/audio)

1. Add the Audio Recorder @ vrch.ai node to your ComfyUI workflow.
2. Configure the Node:
   • Record Mode (record_mode):
     • "Press and Hold":
       • Button Control: Hold the record button to start recording; release to stop.
       • Shortcut Control: Press and hold the selected shortcut key to start recording; release to stop.
     • "Start and Stop":
       • Button Control: Click "START" to begin recording; click "STOP" to end.
       • Shortcut Control: Press the selected shortcut key once to start recording; press again to stop.
   • Recording Parameters:
     • record_duration_max: Set the maximum recording duration (1-60 seconds).
     • loop: Enable or disable loop recording.
     • loop_interval: Set the interval between loop recordings (if loop is enabled).
     • new_generation_after_recording: Enable to automatically trigger a queue generation after recording.
   • Shortcut Configuration:
     • shortcut: Enable or disable the keyboard shortcut for controlling recording.
     • shortcut_key: Select the desired shortcut key (e.g., F1, F2, ..., F12) for controlling the recording.
3. Record Audio:
   • "Press and Hold" Mode:
     • Button Control: Hold the record button to record; release to stop.
     • Shortcut Control: Press and hold the selected shortcut key to record; release to stop.
   • "Start and Stop" Mode:
     • Button Control: Click "START" to begin recording; click "STOP" to end.
     • Shortcut Control: Press the selected shortcut key once to start recording; press again to stop.
   • Loop Mode (Applicable in "Start and Stop" Mode):
     • Click "START" to begin loop recording.
     • Click "STOP LOOPING" to end loop recording.
4. Playback and Output:
   • The recorded audio will appear in the audioUI widget for playback.
   • Use the AUDIO output to connect the recorded audio to other nodes in your workflow.

Note: A countdown displays during the last 10 seconds of recording to inform you of the remaining time.

Node: Get Music Genres @ vrch.ai (vrch.ai/audio)

1. Add the Get Music Genres @ vrch.ai node to your ComfyUI workflow.
2. Configure the Node:
   • Audio Input (audio): Provide an AUDIO input from a previous node in the workflow, such as an audio recorder or a file loader.
3. Analyze Audio:
   • The node processes the input audio to predict its music genre(s).
   • It uses a pre-trained model to analyze the waveform and outputs the predicted genres along with their probabilities.
4. View Results:
   • The predicted genres and their associated probabilities are displayed in a text output format.
   • The results indicate the likelihood of the audio belonging to specific music genres.
5. Connect to Other Nodes:
   • Use the AUDIO output to pass the analyzed audio to other nodes for further processing or playback.
   • Use the STRING output to connect the genre predictions to nodes that require textual input or visualization.

Note: Ensure that the input audio is properly preprocessed and normalized for accurate genre prediction. The node's output is influenced by the quality and clarity of the input audio.
