dj2ls	92087da49f	arq class and fifo queue processing ... moved to a much more clear app design. Huge change, so problems and bugs are no surprise.	2022-01-07 11:25:28 +01:00

dj2ls	3a072a63a6	removed buffer management for N>1 frames per burst ... I decided removing this from the code and keeping everything simple for N=1 frames per burst. N>1 frames per burst need a completely rethinking of buffer management.	2022-01-05 11:38:39 +01:00

dj2ls	3501b4f952	waiting for buffer ... it seems we need to wait a little bit for our modulation data. There are some moments where audio output is stuck a little bit. Maybe python is sometimes faster than the buffer allocation or its a threading problem	2021-12-26 18:41:43 +01:00
