Audio component does not record for users on iOS

[charryshi]

Describe the bug

In my case, the recorded audio is silent. That is to say, if I record for 5 seconds, I will get a player with 5 seconds of recorded audio. But when I play it, I will hear nothing.

I tested record/playback on another site (https://addpipe.com/simple-web-audio-recorder-demo/), and there it works.

Version: gradio-3.41.0 iOS Version:16.7 tested in safari and chrome, both not working.

using code from https://www.gradio.app/guides/real-time-speech-recognition

import gradio as gr from transformers import pipeline import numpy as np

transcriber = pipeline("automatic-speech-recognition", model="openai/whisper-base.en")

def transcribe(audio): sr, y = audio y = y.astype(np.float32) y /= np.max(np.abs(y))

return transcriber({"sampling_rate": sr, "raw": y})["text"]

demo = gr.Interface( transcribe, gr.Audio(source="microphone"), "text", )

demo.launch()
