ChatGPT: Write a go program that sends real-time audio using gRPC streaming

chatgpt-audio-stream.go

package main

import (
	"context"
	"fmt"
	"io"
	"time"

	"google.golang.org/grpc"
	"google.golang.org/grpc/codes"
	"google.golang.org/grpc/status"

	pb "your-proto-package/your-proto-file"
)

const (
	// Address of the gRPC server
	address = "localhost:50051"
)

func main() {
	// Set up a connection to the server
	conn, err := grpc.Dial(address, grpc.WithInsecure())
	if err != nil {
		fmt.Printf("Failed to connect: %v\n", err)
		return
	}
	defer conn.Close()

	// Create a client for the streaming RPC
	client := pb.NewAudioStreamClient(conn)

	// Create a channel to receive audio data from the microphone
	audioChan := make(chan []byte)

	// Start a goroutine to read audio data from the microphone and send it over the channel
	go func() {
		for {
			// Read a chunk of audio data from the microphone
			audioData, err := readAudioFromMicrophone()
			if err != nil {
				fmt.Printf("Failed to read audio: %v\n", err)
				return
			}

			// Send the audio data over the channel
			audioChan <- audioData
		}
	}()

	// Create a context with a timeout
	ctx, cancel := context.WithTimeout(context.Background(), time.Minute)
	defer cancel()

	// Create a stream for the RPC
	stream, err := client.SendAudio(ctx)
	if err != nil {
		fmt.Printf("Failed to create stream: %v\n", err)
		return
	}

	// Send the audio data from the channel to the stream
	for {
		select {
		case audioData := <-audioChan:
			// Send the audio data to the server
			err = stream.Send(&pb.AudioPacket{Data: audioData})
			if err != nil {
				fmt.Printf("Failed to send audio: %v\n", err)
				return
			}
		case <-ctx.Done():
			// Check if the context has expired
			if ctx.Err() == context.Canceled {
				fmt.Printf("Stream canceled by client\n")
			} else {
				fmt.Printf("Stream canceled by server: %v\n", ctx.Err())
			}
			return
		}
	}
}

// readAudioFromMicrophone reads a chunk of audio data from the microphone
func readAudioFromMicrophone() ([]byte, error) {
	// Replace this with your own code to read audio data from the microphone
	}

Does not include protobuf definition and reading from the microphone is sadly left as an exercise for the reader
