Bill Somerville	0cf14dfcc9	Remove user adjustable audio buffer sizes from Settings ... Fixed buffer sizes are used. Rx use s 3456 x 1st downsample rate x 5 audio frames of buffer space. On Windows this means that each chunk (periodSize()) delivered from the audio stream is our initial DSP processing chunk size, thus matching audio buffer latency exactly with WSJT-X's own front end latency. This should result in optimal resilience to high system loads that might starve the soundcard ADC of buffers to fill and case dropped audio frames. For Tx a buffer sufficient for 1 s of audio is used at present, on Windows the period size will be set to 1/40 of that which gives reasonably low latency and plenty of resilience to high system loads that might starve the soundcard DAC of audio frames to render. Note that a 1 s buffer will make the "Pwr" slider slow to respond, we may have to reduce the Tx audio buffer size if this is seen as a problem.	2020-08-11 13:48:01 +01:00
