minim.createSample(float[] samples, int sampleRate);
minim.createSample(float[] samples, int bufferSize, int sampleRate);
minim.saveSample(AudioSample sample, String filename);

public void nrtDump(float[] inputSamples) {
for(int i = 0; i < inputSamples.length; i += bufferSize()) {
float[] cur = new float[bufferSize()];
int remaining = inputSamples.length – i;
int curLength = Math.min(remaining, bufferSize());
System.arraycopy(inputSamples, i, cur, 0, curLength);
splitter.samples(cur);
}
}

And then in my main code I wrote this:

audio = minim.loadSample(“audiofile.wav”, 512);
float[] leftChannel = audio.getChannel(BufferedAudio.LEFT);
float[] reversed = reverse(leftChannel);
AudioRecorder recorder = minim.createRecorder(audio, “data/output.wav”, true);
recorder.beginRecord();
audio.nrtDump(reversed);
recorder.endRecord();
recorder.save();

With that said, something like: minim.createSample(float[] samples); (returning an AudioSample) and minim.saveSample(AudioSample sample); would be amazing.

It’d be really great if AudioSample had a constructor that just allowed you to pass a float[] to it, and then a method that allowed you to save the AudioSample.

Also, I was concerned about length constraints, but I think you should run into memory problems first. Java arrays can be 2^27 elements long, or about 50 minutes at 44.1kHz.
