AMR MP3 Converter converts AMV files to AWB format. The software is an all in one audio converter that supports more than 90 audio and video files as input, and converts to popular formats such as MP3, WAV, AAC, M4A, OGG, WMA, and AWB.
AMR MP3 Converter also supports batch conversion, and is full compatible with Vista and Windows 7.
What is AMV?
AMV is a proprietary video file format, produced for MP4 players, as well as S1 MP3 players with video playback. There are now two different MTV formats: the older one for the Actions chip, and a newer one for ALi's M5661 chip. This format for ALi one was ALIAVI.
The container is a modified version of AVI. The video format is a variant of motion JPEG, with fixed rather than variable quantisation tables. The audio format is a variant of IMA ADPCM, where the first 8 bytes of each frame are origin (16 bits), index (16 bits) and number of encoded 16-bit samples (32 bits); all known AMV files run sound at 22050 samples/second.
Low decoder overhead is paramount as the S1 MP3 players have very low-end processors (a Z80 variant). Video compression ratio is low ¡ª around 4 pixels/byte, compared with over 10 pixels/byte for MPEG-2 -- though as the files are of low resolution (96¡Á96 up to 208¡Á176) and frame rate (10, 12, or 16 frame/s), file sizes are small in bytes per second. With a resolution of 128¡Á96 pixels and a framerate of 12 frame/s, a 30-minute video will be compressed into 80 MB.
What is AWB?
AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB). G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector.
A common file extension for AMR-WB file format is .awb. There also exists another storage format for AMR-WB that is suitable for applications with more advanced demands on the storage format, like random access or synchronization with video. This format is the 3GPP-specified 3GP container format based on ISO base media file format. 3GP also allows use of AMR-WB bit streams for stereo sound.
The AMR-WB bitrates are 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05 and 23.85 kbps. Compared to narrowband speech codecs (like AMR) optimized for traditional telephone voice quality of 300-3400 Hz, the AMR-WB codec's wider bandwidth of 50-7000 Hz provides excellent speech quality.
