Windows 10 64bit Change AC3 sound into AMR format in Windows 10 64bit Win8.1, About .AC3 Audio extension format, Dolby Digital is the marketing Name for a series of lossy audio compression technologies developed by Dolby Laboratories. Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound, with five channels for normal-range speakers (20 Hz ¨C 20,000 Hz) (right front, center, left front, right rear and left rear) and one channel (20 Hz ¨C 120 Hz) for the subwoofer driven low-frequency effects. Mono and stereo modes are also supported. AC-3 sound supports audio sample-rates up to 48KHz. Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The LaserDisc version of Clear and Present Danger featured the very first Home theater Dolby Digital mix in 1995.

What is AMR codec ? The AMR-WB codec adapts the bit-rate allocation between speech and channel coding, optimising speech quality to prevailing radio channel conditions. While providing superior voice quality over the existing narrowband standards, AMRWB is also very robust against transmission errors due to the multi-rate operation and adaptation. The adaptation is based on similar principles as in the previously standardised 3GPP/ETSI AMR codec (referred to also as the AMR narrow-band codec, AMR-NB).
.AMR file header of common across all AMR-NB files is always set to: 0x23, 0x21, 0x41, 0x4D, 0x52, 0x0A, if the header is not as it should be, the file is probably corrupted and should not be used.
