Golang如何将pcm格式音频转为mp3格式

package main 
import ("
os"
"
os/exec"
) 
func convertPcmToMp3(inputFile string, outputFile string) error {cmd := exec.Command("
ffmpeg"
, "
-f"
, "
s16le"
, "
-ar"
, "
44100"
, "
-ac"
, "
2"
, "
-i"
, inputFile, outputFile)err := cmd.Run()if err != nil {return err} 
    return nil} 
func main() {inputFile := "
input.pcm"
outputFile := "
output.mp3"
 
    err := convertPcmToMp3(inputFile, outputFile)if err != nil {panic(err)} 
    os.Remove(inputFile)}

这段代码使用了ffmpeg来将PCM格式音频文件转换为MP3格式。请确保系统中已安装ffmpeg命令行工具。
