Kostenloser Online HEVC zu NIST Konverter

HEVC or h.265 is the most advanced codec for now because it has the lowest bitrate without losing the image quality. The codec has three main features that distinguishes it from others: parallel decoding, random access to images within the video stream and larger maximum block size. HEVC is aimed to offer the same level of video quality as AVC (h.264), but with improved compression, that is why a video file compressed with the codec will be twice smaller.

SPHERE (SPeech HEader Resources) is a file format defined by NIST (National Institute of Standards and Technology) and is used with speech audio. SoX can read these files when they contain μ-law and PCM data. It will ignore any header information that says the data is compressed using shorten compression and will treat the data as either μ-law or PCM. This will allow SoX and the command line shorten program to be run together using pipes to encompasses the data and then pass the result to SoX for processing.
