How do I go from base64 string to wav file in Node.js | ElevenLabs | Page 1

AI-generated Answer for johnwilla

The information provided does not include a direct method to convert a base64 string to a wav file in Node.js. However, it does provide a Python example of how to convert a base64 string to a wav file. Here's the Python code for reference:

from scipy.io import wavfile
from pydub import AudioSegment
from io import BytesIO

def tts_out(text: str):
    response = elevenlabs_client.text_to_speech.convert(
        text=text,
        voice_id="xxxxxxxxxxxxxxx",
        optimize_streaming_latency="0",
        output_format="mp3_22050_32",
    )

    audio_stream = BytesIO()

    for chunk in response:
        if chunk:
            audio_stream.write(chunk)

    audio_stream.seek(0)
    audio = AudioSegment.from_mp3(audio_stream)
    wav_io = BytesIO()
    wav_file = audio.export(wav_io, format="wav")
    wav_io.seek(0)

    sample_rate, audio_data = wavfile.read(wav_io)

    return (sample_rate, audio_data)

This Python code uses the scipy.io.wavfile and pydub.AudioSegment libraries to convert the audio stream to a wav file. You might be able to find similar libraries or methods in Node.js to achieve the same result.
