音频频谱动效
作者你好,我遇到一个问题就是session设置声道的时候(try session.setPreferredInputNumberOfChannels(1)),不管是单声道还是双声道,都会抛出异常是为什么呢?不设置的话,频谱动画里面只会显示左声道的
作者你好,如题,我在实时获取音频的时候,在回调方法
inputNode.installTap(onBus: 0, bufferSize: AVAudioFrameCount(VTRecognizeController.bufSize), format: inputNode.outputFormat(forBus: 0)) { [weak self] (buffer, time) in }
里面实时更新spectrumView么不是,我把这个操作放在主线程里的,然后模拟器运行可以看到频谱展示正常,但是真机情况下,音量柱(频谱的幅度就特别小,我把手机音量开到最大的),analyzer.analyse(buffer, withAmplitudeLevel: 80)传值从一开始你的25我调到80,效果也是不太明显,请问什么原因呢?
如题,作者你好,我最近在做实时语音的功能,找了好多天音频频谱都没有发现好的,你的算是找到的里面比较好的了,但是运行demo看都是根据本地音频文件展示频谱的,我要根据录音实时展示请问怎么做呢?
我是一边播音乐一边录音,有很大的回声干扰,这个要怎么做
大佬请指点
感谢大佬!~
if (self.engine.isRunning == YES)
{
[self.player play];
}else{
[self.engine startAndReturnError:nil];
[self.player play];
}
我是添加的这个 去区分 显示 AVAudioEngine 并没有 start ... 仍然舔大佬
