State of the art lossy codecs and surround formats Reply #25 – 2015-04-13 15:51:02 Quote from: SokilOff on 2015-04-13 01:41:22Quote from: IgorC on 2015-04-12 18:36:32It can lead to same situation as for JPEG image format. All its patents have been expired and there were a number of a newer image compression formats (JPEG2000, JPEG XR, WebP (intra VP8) and lately HEVC-based BPG). But none of them come any closer to JPEG's status of leading/most popular image format.The same story will probably happen with mp3. We are just 2 years away from expiring it's last patents in April 2017. With zillions mp3 supporting devices around the world it will seriously reduce importance of free lossy audio codecs like ogg or opus, at least at high bitrates 128k+.IIUC, the last mp3 decoder patent in the USA expires in 2 weeks.
