How to use freetts create/generate a wave file

本文介绍了如何使用SingleFileAudioPlayer将音频流写入文件。通过简单的示例代码,展示了设置音频播放器并确保调用close方法以完成文件写入的过程。此外,还提供了创建名为freetts.wav波形文件的方法。

SingleFileAudioPlayer streams audio to a file.

 

The SingleFileAudioPlayer doesn't write to the file until its close method is called. When an application calls setAudioPlayer on a voice, it is responsible for calling the close method. As such, you need to do just a little more work.

Try starting with just the very simple FreeTTS HelloWorld program and then modifying it very slightly as follows:

SingleFileAudioPlayer sfap = new SingleFileAudioPlayer();
helloVoice.setAudioPlayer(sfap);
helloVoice.speak("Thank you for giving me a voice. "
+ "I'm so glad to say hello to this world.");
sfap.close();

 

 

and this can create a wave file names "freetts.wav".

Your question seems to be a mix of philosophical or spiritual concepts and programming, which makes it somewhat ambiguous in terms of providing a direct programming solution. However, I will attempt to interpret your request as a need for creating or working with code that symbolizes harmony, communication, or divine principles, possibly through mathematics or music. Let’s assume you want to create a program that represents "divine harmony" using mathematical music (e.g., generating harmonious frequencies). Below is an example of how you can use Python to generate sine waves, which represent musical notes, and combine them to create harmonious sounds. ### Example: Generating Harmonious Musical Notes ```python import numpy as np import sounddevice as sd from scipy.io.wavfile import write # Function to generate a sine wave for a given frequency and duration def generate_note(freq, duration, sample_rate=44100): t = np.linspace(0, duration, int(sample_rate * duration), False) note = np.sin(freq * t * 2 * np.pi) return note # Combine multiple notes to create harmony def create_harmony(notes, durations): sample_rate = 44100 combined_audio = np.zeros(max(int(sample_rate * max(durations)), 1)) for i, note_freq in enumerate(notes): note = generate_note(note_freq, durations[i], sample_rate) combined_audio[:len(note)] += note # Normalize the audio to prevent clipping combined_audio /= np.max(np.abs(combined_audio)) return combined_audio, sample_rate # Define the notes (frequencies) and their durations notes = [261.63, 329.63, 392.00] # C4, E4, G4 (a major chord) durations = [2, 2, 2] # Duration of each note in seconds # Create the harmony harmony, sample_rate = create_harmony(notes, durations) # Play the harmony sd.play(harmony, sample_rate) sd.wait() # Save the harmony as a WAV file write("divine_harmony.wav", sample_rate, harmony) ``` ### Explanation: The above code generates a harmonious sound by combining three musical notes (C4, E4, G4) into a major chord. Here's a breakdown of the code: 1. **`generate_note`**: This function generates a sine wave for a given frequency and duration. 2. **`create_harmony`**: This function combines multiple notes into a single audio waveform. 3. **Normalization**: The combined audio is normalized to prevent distortion. 4. **Playback and Saving**: The generated harmony is played back using `sounddevice` and saved as a `.wav` file. This program represents "divine harmony" through mathematical precision in generating musical notes. --- ###
