#8906 still not solve audio play out high delay

[steven8274]

I met the audio play out high delay problem.However, even I use the #8906 source code to install gradio, the problem not was solved.There is still 3~4s delay and audio playing is not smooth(has some gap, look like lack of audio data).This is my demo code:

import gradio as gr
from pydub import AudioSegment
from time import sleep
import numpy as np
import datetime

audio_list = []
def add_to_stream(audio):
    sleep(0.05)
    global audio_list
    audio_list.append(audio)

with gr.Blocks() as demo:
    inp = gr.Audio(sources=["microphone"], streaming=True)
    inp.stream(add_to_stream, [inp], [])

    stream_as_file_btn = gr.Button("Stream as File")
    stream_as_file_output = gr.Audio(streaming=True)
    stream_as_file_output.autoplay = True

    def stream_file():
        global audio_list
        while True:
            while len(audio_list) == 0:
                print('stream out pull data, but no data available now...')
                sleep(0.05)
            chunk = audio_list[0]
            audio_list = audio_list[1:]
            print('yield audio chunk, samples: {}, cached audio chunks: {}, at: {}'.format(len(chunk[1]), len(audio_list), datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S.%f")))
            yield chunk

    stream_as_file_btn.click(
        stream_file, [], stream_as_file_output
    )


if __name__ == "__main__":
    demo.launch(server_name='0.0.0.0', server_port=8000)

I figured audio data output speed via log, it's coincident with it's sample rate.

Demo usage:
1.click 'stream_as_file_btn' to start audio data fetching.
2.click 'inp' audio component's recording button to start generating audio data.

After about half an second, you will see 'yield audio chunk...', which means audio data beging outputing.

Did I miss something?Thanks in advance.
