WebMost DAWs offer six buffer size options: 32, 64, 128, 256, 512, and 1024. Some DAWs, like Pro Tools, tie their buffer size options to the session’s sample rate. At 96 kHz, Pro Tools supports 64, 128, 256, 512, 1024, and 2048, while at 44.1 or 48 kHz, it goes back to the standard 32 through 1024 volumes. Buffer size options in Logic Pro X. WebJan 26, 2024 · Just divide the buffer size by the number of samples per second (sample rate). For example, if you have your buffer size set to 256 and your sample rate at 48 kHz, divide those two and you’ll get 5.3 ms. If you change the settings to 512 and 48 kHz, however, it’ll average out to 10.6 ms.

Sample rate vs buffer size

WebJul 4, 2024 · 24 bit 44.1khz is all you need, buffer size is essentially the amount of latency (time you allow for your computer to process the audio) and increasing it increases that latency but decreases cost on your CPU. Increasing sample rate and bit depth also decreases that latency but increases CPU cost. WebExperimenting with your buffer size and sample rate can give you great improvements. Furthermore, the new v4 drivers for the iD range and Sono mean you can use lower buffer sizes with higher stability in larger sessions.
