Hi All, I am working on an audio logger for a University radio station. The idea is to log all data to disk, 24/7/365 without interruption. What I am finding is that to record 1s of audio, it takes 1s of waiting, plus a small additional bit of time to copy that audio into userspace, about 1.8 ms on the system I am using. Therefore, in a day, I can not record a full day of audio. I am not using the MMAP functions, which I suppose might reduce that delay, if it is mostly caused by copying the data. Does that sounds like a solution, or am I missing something obvious? Or, if I am reinventing the wheel, does anyone know of a readymade open source program for 24/7/365 logging?
Thanks, Robin. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
