Hi,
First of all, thanks you for the effort porting Librosa to Java. I think that could be very useful.
I have tested the library in windows 10 and i found that when converting to mono audio, the library fails because of the method used to round the result of the mean between audio channels.
Error in:
meanBuffer[q] = Float.parseFloat(df.format(frameVal / mChannels));
Due to decimal format:
DecimalFormat df = new DecimalFormat("#.#####");
Changing the format solves the issue
DecimalFormat df = new DecimalFormat("#,#####");
It seems that the format is related to platform or platform config(assuming you don't have such an error). I don't know why to use this type of rounding that don't take advantage of float and double precision. Why not just casting to float?
