hallo, i'm using AudioFileBuffer from the max mxj api to read soundfiles with varying sample sizes. when i try to output the floating point data from the buf field, i get correct results only for 16 bit files. 8 bit, 24 bit and 32 bit are all wrong, which to me looks like errors in int-to-float-conversion. do i overlook something here? thanks, volker.

simple test class:

import com.cycling74.max.*; import com.cycling74.msp.*;

public class test_afb extends MaxObject { private AudioFileBuffer afb = null;

public test_afb (Atom[] args) { declareInlets(new int[]{DataTypes.ALL}); declareOutlets(new int[]{DataTypes.ALL}); }

/* load soundfile----------------------------------------------------*/ publicvoid open( String path ) { String fname = MaxSystem.locateFile(path); post("filename: "+fname);

try { afb = new AudioFileBuffer(fname); System.out.println("frame length: "+ afb.getFrameLength()); System.out.println("samp size in bits: "+ afb.getSampleSizeInBits ()); System.out.println("num channels: "+ afb.getChannels()); System.out.println("big endian: "+ afb.isBigEndian()); System.out.println("sample rate: "+ afb.getSampleRate()); } catch(Exception e) { error("mxj test_afb: sorry, can't open that file!"); } }

/* output sample value at index from channel 1-------------------*/ publicvoid inlet (int index) { outlet(0, afb.buf[0][index]); } }

simple test patch:
