Wrapping synchronous Buffer operations in a function

Usage Questions
2

Welcome @heretogo , thanks for your question!

Do you mean you’d like to have the function return as if it were a synchronous function in the main thread? I don’t think it can be done without running the whole thing in a Routine or similar, because the processing and buffer fetching from the server are both asynchronous, so you need to make things block.

(
~getFrequencies = {|in|
    var out; 
    var cond = Condition.new; 
    var outBuf = Buffer.new; 
    FluidBufPitch.process(s, in, features: outBuf,
        action:{outBuf.loadToFloatArray(
            action: {|x| 
                out = x.reshape((x.size()/2).asInteger, 2); 
                cond.unhang; 
            }
        )
        }
    );
    cond.hang; 
    out
};

fork{   
    b = Buffer.read(s, File.realpath(FluidBufPitch.class.filenameSymbol).dirname.withTrailingSlash ++ "../AudioFiles/Tremblay-ASWINE-ScratchySynth-M.wav");
    s.sync;  
    ~getFrequencies.value(b).postln; 
}
)
