Hello friends!  
I want to read some audio files previously loaded into &nbsp;memory:

```
File sample0001 (String(appDirPath + appSubPath + "/sample0001.wav"));
 MemoryMappedFile mappedfile_sample001 (sample0001 , juce::MemoryMappedFile::readOnly);
```

But I don't know how to do it... can you help me?

Thanks in advance!

There's already a class to do this: see WavAudioFormat::createMemoryMappedReader
