This codec API is also available in C++ as libFLAC++. The reference implementation of FLAC compiles on many platforms, including most Unix (such as Solaris, BSD) and Unix-like (including Linux), Microsoft Windows, BeOS, and OS/2 operating systems. There are build-systems for autoconf/automake, MSVC, Watcom C, and Xcode. There is currently no multicore support in libFLAC, but utilities such as GNU parallel and various graphical frontends can be used to spin up multiple instances of the encoder. FLAC playback support in portable audio devices and dedicated audio systems is limited compared to formats such as MP3 or uncompressed PCM. FLAC support is included by default in Windows 10, Android, BlackBerry 10 and Jolla devices. In 2014, several aftermarket mobile electronics companies introduced multimedia solutions that include support for FLAC. These include the NEX series from Pioneer Electronics and the VX404 and NX404 from Clarion. The European Broadcasting Union (EBU) has adopted the FLAC format for the distribution of high quality audio over its Euroradio network. The Windows operating system has supported native FLAC integration since the introduction of Windows 10. The Android operating system has supported native FLAC playback since version 3.1. macOS High Sierra and iOS 11 add native FLAC playback support.Among others the Pono music player and streaming service used the FLAC format. Bandcamp insists on a lossless format for uploading, and has FLAC as a download option. The Wikimedia Foundation sponsored a free and open-source online ECMAScript FLAC tool for browsers supporting the required HTML5 features.
Carotidynia is a syndrome characterized by unilateral (one-sided) tenderness of the carotid artery, near the bifurcation. It was first described in 1927 by Temple Fay. The most common cause of carotidynia may be migraine, and then it is usually self-correcting. Common migraine treatments may help alleviate the carotidynia symptoms. Recent histological evidence has implicated an inflammatory component of carotidynia, but studies are limited. Carotid arteritis is a much less common cause of carotidynia, but has much more serious consequences. It is a form of giant cell arteritis, which is a condition that usually affects arteries in the head. Due to this serious condition possibly causing carotidynia, and the possibility that neck pain is related to some other non-carotidynia and serious condition, the case should be investigated by a medical doctor. Because carotidynia can be caused by numerous causes, Biousse and Bousser in 1994 recommended the term not be used in the medical literature. However, recent MRI and ultrasound studies have supported the existence of a differential diagnosis of carotidynia consistent with Fays characterization. References
