![]() ![]() ![]() The available sample rates depend upon the capabilities of your audio hardware. Generally, a higher sample rate results in 'better' sound quality, in the sense of greater 'clarity' in the high end.Ī sample rate of 44.1 kHz results in 'CD quality' audio. 'Sample Rate' (ASIO and MME)Īltering the sample rate affects the 'frequency response' of the recordings you make. In contrast with these rather high latencies, ASIO provides latencies <= 10 ms, which makes recording real-time 'live' performances possible. from a microphone) will be audible on the output (e.g. Total Latency = Input + Output Latency => 232 ms + 139 ms = 371 msĪn incoming signal (e.g.Output Latency = Playback Buffers * BlocksizeĮ.g.Input Latency = Record Buffers * BlocksizeĮ.g.The total audio system latency can be calculated as follows: Latency is the delay caused when the computer processes sound on its way in or out of the system. Increasing the number of buffers helps eradicate 'glitches' in the sound - but more buffers also results in greater 'latency'. You can set the number of memory buffers to be used for playback and recording independently. KRISTAL 'caches' all incoming and outgoing audio data in several memory 'buffers' to ensure smooth, uninterrupted sound. You should experiment to find the optimum settings for your system. On the other hand, a too small block size may result in interrupted playback. changes to volume, pan and effects parameters will happen more immediately. With a smaller block size, KRISTAL will be more 'responsive', e.g. If you're a using a standard MME audio device, the block size can be changed directly from within KRISTAL. If you're using an ASIO compatible audio device, the block size is determined by the ASIO driver it can usually be changed in the driver's control panel. a block size of 1024 audio frames equals approximately 23ms of audio material at a 44.1 kHz sample rate. here.ĪSIO drivers usually provide their own control panel.Īll mixing and effect processing is done in blocks of this size, e.g. ![]() The 'Audio Setup' may differ, depending on the currently selected Audio Output device:įor MME devices you can set Blocksize, Playback Buffers, etc.
