Overview:
Audio file processing is often encountered in Web development, such as audio uploading and audio format conversion , audio cutting, etc. This article will introduce how to use PHP to implement some common functions of audio file processing.
// 上传文件保存目录 $uploadDir = 'audio/'; // 随机生成文件名 $fileName = uniqid() . '.mp3'; // 检查文件类型和大小 if ($_FILES["audio"]["type"] == "audio/mpeg" && $_FILES["audio"]["size"] < 5000000) { // 移动上传的文件到指定目录 move_uploaded_file($_FILES["audio"]["tmp_name"], $uploadDir . $fileName); echo "文件上传成功!"; } else { echo "只允许上传小于5MB的 MP3 文件!"; }
// 源文件和目标文件路径 $sourceFile = 'audio/source.mp3'; $destinationFile = 'audio/converted.wav'; // 创建 ffmpeg 命令 $command = "ffmpeg -i " . $sourceFile . " " . $destinationFile; // 执行命令 exec($command); echo "音频格式转换完成!";
// 源文件和目标文件路径 $sourceFile = 'audio/source.mp3'; $destinationFile = 'audio/trimmed.mp3'; // 创建 ffmpeg 命令 $command = "ffmpeg -i " . $sourceFile . " -ss 00:00:00 -t 00:00:10 -acodec copy " . $destinationFile; // 执行命令 exec($command); echo "音频剪切完成!";
