Hi, I was able to solve it using the inherent java audio class javax.sound.sampled. I convert an input audio file encoded in uLaw to PCM and then write the PCM file into an Audiostream. Code is given below. try{ File filein = new File("C:/sourcefile.wav"); File fileout = new File("C:/PCMfile.wav"); AudioInputStream sourceaudio = AudioSystem.getAudioInputStream(filein); AudioFormat format = sourceaudio.getFormat(); if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) { format = new AudioFormat( AudioFormat.Encoding.PCM_SIGNED, format.getSampleRate(), format.getSampleSizeInBits() * 2, format.getChannels(), format.getFrameSize() * 2, format.getFrameRate(), true); } AudioFileFormat.Type targettype = AudioFileFormat.Type.WAVE; AudioInputStream targetaudiostream = AudioSystem.getAudioInputStream(format, sourceaudio); AudioSystem.write(targetaudiostream, targettype, fileout); System.out.println("PCM encoded file generated successfully."); sourceaudio.close(); targetaudiostream.close(); } catch (Exception e) { out.println("Error in audio format conversion"); e.printStackTrace(); }

I give the following advice about once a month; it often helps me track down the nastier heap errors: Try enabling the page heap[^] for your process. Follow these steps: 1. Download and install WinDBG[^]. 2. Select “Start”->“All Programs”->“Debugging Tools for Windows”->“Global Flags”. 3. Select the “Image File” tab. 4. In the “Image: (TAB to refresh)” edit control enter the name of your app then press TAB. Just the name with the extension; not the full path. 5. Tick the following: - “Enable page heap” - “Enable heap tail checking” - “Enable heap free checking” - “Enable heap parameter checking” - “Enable heap validation on call” - “Create user mode stack trace database” 6. Press “Apply”. 7. Debug your application. Any debugger will do but with WinDBG you have access to the stack traces of allocations via the !heap –p –a command, for example. When a heap problem is detected a breakpoint will be generated. 8. When done un-tick all the options you ticked, press “Apply” then dismiss GFlags. This step is important as if it’s skipped all applications named as entered in step 4 will run with the page heap enabled. Note that when using the page heap your application will run much slower than normal and consume way more memory. It’s good to have a beefy machine to do such tests; and such tests should be ran regularly on all applications you develop as part of regular testing activities. If I find a part of my application that’s too slow with the page heap enabled I optimize the memory allocation in that region. Steve

hey, thanks for your advice. i solved the problem myself. as you see in my code, i was using an array. i didnt need to use that. i used only a single object and treated the three transactions as a single transaction. it works now.!! - Moonis
