swift – 将pcm加载到AVAudioPCMBuffer中

概述我有这个代码： func loadSoundfont(_ pitch : String) { let path: String = Bundle.main.path(forResource: "\(self.id)/\(pitch)", ofType: "f32")! let url = URL(fileURLWithPath: path) do { le 我有这个代码：

func loadSoundFont(_ pitch : String) {    let path: String = Bundle.main.path(forResource: "\(self.ID)/\(pitch)",ofType: "f32")!    let url = URL(fileURLWithPath: path)    do {        let file = try AVAudiofile(forReading: url,commonFormat: AVAudioCommonFormat.pcmFormatfloat32,interleaved: true)        let format = file.processingFormat        let capacity = AVAudioFrameCount(file.length)        self.buffer = AVAudioPCMBuffer(pcmFormat: format,frameCapacity: capacity)        try file.read(into: self.buffer!)    } catch let error as NSError {        print("ERROR HERE",error.localizedDescription)    }}

我得到以下错误：1954115647这是：kAudiofileUnsupportedfileTypeError

我的A4.f32文件包含一个PCM浮动32.这里有什么我想念的吗？我的文件中没有标题,是否可能导致此问题？

解决方法 感谢Rhythmic Fistman的评论,我自己去加载它,就这样：

func loadSoundFont(_ pitch : String) {    let path: String = Bundle.main.path(forResource: "\(self.ID)/\(pitch)",ofType: "f32")!    let url = URL(fileURLWithPath: path)    do {        let data = try Data(contentsOf: url)        let format = AVAudioFormat(commonFormat: .pcmFormatfloat32,sampleRate: 44100,channels: 2,interleaved: true)        self.buffer = AVAudioPCMBuffer(pcmFormat: format,frameCapacity: AVAudioFrameCount(data.count))        self.buffer!.floatChannelData!.pointee.withMemoryRebound(to: UInt8.self,capacity: data.count) {            let stream = OutputStream(toBuffer: ,capacity: data.count)            stream.open()            _ = data.withUnsafeBytes {                stream.write(,maxLength: data.count)            }            stream.close()        }    } catch let error as NSError {        print("ERROR HERE",error.localizedDescription)    }}
