核心audio：当一个数据包= 4个字节时，一个数据包如何能够=一个字节

我正在学习核心audio中的核心audio转换服务，我在他们的示例代码中被这个例子所震惊： while(1) { // wrap the destination buffer in an AudioBufferList AudioBufferList convertedData; convertedData.mNumberBuffers = 1; convertedData.mBuffers[0].mNumberChannels = mySettings->outputFormat.mChannelsPerFrame; convertedData.mBuffers[0].mDataByteSize = outputBufferSize; convertedData.mBuffers[0].mData = outputBuffer; UInt32 frameCount = packetsPerBuffer; // read from the extaudiofile CheckResult(ExtAudioFileRead(mySettings->inputFile, &frameCount, &convertedData), "Couldn't read from input file"); if (frameCount == 0) { printf ("done reading from file"); return; } // […]
