By adding the following section to the initialisation file the audio buffer sizes and audio thread priority may be adjusted. [Tune] Audio\InputBufferFrames=1200 Audio\OutputBufferMs=1000 Audio\ThreadPriority=4 The values above are the program defaults that will be used if the initialisation parameters are omitted. Thread prioritis are the QThread::Priority enumumeration values. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3576 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
