Sorry, I didn’t mention that `readFromAudioReader` is not available anymore. The `AudioFormatReader` `read()` is what you need. Just search the forum, there’s plenty of answers for this - here’s another thread:

> Hi, Right now I am trying to combine the AudioSampleBuffer given from the proccessBlock method, with an AudioSampleBuffer that I created from a WAV file. I am mixing them using the addFrom method. When I am encountering is a ‘buzzing’ sound ontop of the other track when I apply my filter, as opposed to the desired mix of the two buffers. When I create a reader for the WAV, usingFloatingPointData is false. The sample rate of the WAV matches the sample rate of the audio file I’ve been testing…

I rewrote the code (but didn’t tested). Call `read()` and increment `sourceStartSample` in each iteration of `processBlock` by `numReadSamples`. Don’t forget to reset it when it goes to end, fill the rest of the `outputBuffer` with zeros when there’s not enough samples (or `clear()` at the beginning of iteration), etc.

```
AudioSampleBuffer outputBuffer;
String path = "someFile.wav";
int64 sourceStartSample = 0;
int numReadSamples = 512;

File soundFile = File(path);
AudioFormatManager manager;
manager.registerBasicFormats();
AudioFormatReader* reader = manager.createReaderFor(soundFile);
outputBuffer.setSize((int)reader->numChannels, (int)reader->lengthInSamples);
reader->read(&outputBuffer, 0, jmin((int)reader->lengthInSamples, numReadSamples), sourceStartSample, true, true);

```

Combine the `FileChooser` (from the tutorial) with this and you might get what you need.

Or you can implement it similary to how the [SoundPlayer](https://www.juce.com/doc/classSoundPlayer) does.

About over engineering - one shouldn’t forget that JUCE is cross-platform and it doesn’t use any external libraries AFAIK.
