c++(qt)播放wav文件的四种方式
作者:互联网
//方法一(要符合RIFF规范)
1 QSound::play("E:/Projects/报警声1-1.wav");
//方法二(要符合RIFF规范)
1 QSoundEffect in_effect; 2 in_effect.setSource(QUrl::fromLocalFile("E:/Projects/报警声1-1.wav")); 3 in_effect.setLoopCount(QSoundEffect::Infinite); 4 in_effect.setVolume(0.25f); 5 in_effect.play();
//方法三(要符合RIFF规范)
1 QFile in_wavFile; 2 in_wavFile.setFileName("E:/Projects/报警声2-1.wav"); 3 in_wavFile.open(QIODevice::ReadOnly); 4 QAudioFormatin_audioFormat; 5 in_audioFormat.setSampleRate(44100); 6 in_audioFormat.setChannelCount(2); 7 in_audioFormat.setSampleSize(16); 8 in_audioFormat.setCodec("audio/pcm"); 9 in_audioFormat.setByteOrder(QAudioFormat::LittleEndian); 10 in_audioFormat.setSampleType(QAudioFormat::UnSignedInt); 11 QAudioOutput*in_audio=newQAudioOutput(in_audioFormat,0); 12 in_audio->start(&in_wavFile);
//方法四(限MP3格式编码的wav文件)
1 QMediaPlayer *in_player = new QMediaPlayer; 2 in_player->setMedia(QUrl::fromLocalFile("E:/Projects/报警声2-1.wav")); 3 in_player->setVolume(50); 4 in_player->play();
