使用 AVFoundation 在 iPhone 模拟器中录制音频时出现以下错误。我的代码在设备上运行良好。

有任何想法吗？提前致谢。

在我的情况下，显示错误是因为我使用了错误的比特率：

我忘记了我使用Kbps并AVEncoderBitRateKey使用bps。所以，在我将比特率乘以 后1000，错误就消失了。

录制为 m4a 格式（AVFormatIDKey = kAudioFormatMPEG4AAC）时，我在模拟器中录制音频时也遇到了问题。没有录制音频，控制台日志包含“AudioConverterFillComplexBuffer”错误。

但是，录制为 .caf 格式 (kAudioFormatAppleIMA4) 确实有效，这对于某些人来说可能是一种解决方案。

recordSettings = [NSDictionary
                  dictionaryWithObjectsAndKeys:
                  [NSNumber numberWithInt:AVAudioQualityMin],
                  AVEncoderAudioQualityKey,
                  [NSNumber numberWithInt:16],
                  AVEncoderBitRateKey,
                  [NSNumber numberWithInt: 1],
                  AVNumberOfChannelsKey,
                  [NSNumber numberWithFloat:16000.0],
                  AVSampleRateKey,
                  [NSNumber numberWithInt: kAudioFormatAppleIMA4],
                  AVFormatIDKey,
                  nil];
