AMR MP3 Converter converts DRC 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 supports batch conversion, and is full compatible with Vista and Windows 7.
Click "Add Files" to choose DRC files and then add them to conversion list.
Choose one or more DRC files you want to convert and then click Open.
Click button "Convert" to convert all DRC files to AWB format.
The software is converting DRC files to AWB format.
When conversion completes, you could right-click converted file and choose "Play Destination" to play the outputted AWB file; or choose "Browse Destination Folder" to open Windows Explorer to browse the AWB file.
What is DRC?
The specification was finalised on 21 January 2008, and further developments will only be bug fixes and constraints. In September of that year version 1.0.0 of the reference implementation was released which corresponds to an intra-frame only subset known as Dirac Pro, which has been proposed to the SMPTE for standardisation as VC-2. Version 2.2.3 of the full Dirac specification, including motion compensation and inter-frame coding, was issued a few days later. Dirac Pro was used internally by the BBC to transmit HDTV pictures at the Beijing Olympics in 2008.
The format implementations are named in honour of the theoretical physicists Paul Dirac and Erwin Schrodinger, who shared the 1933 Nobel Prize in physics.
Dirac supports resolutions up to HDTV (1920x1080) and greater and is claimed to provide significant savings in data rate and improvements in quality over video compression formats such as MPEG-2 Part 2, MPEG-4 Part 2 and its competitors, e.g. Theora, and WMV. Dirac's implementers make the preliminary claim of "a two-fold reduction in bit rate over MPEG-2 for high definition video", which makes it comparable to the latest generation standards such as H.264/MPEG-4 AVC and VC-1.
Dirac supports both constant bit rate and variable bit rate operation. When the low delay syntax is used, the bit rate will be constant for each area (Dirac slice) in a picture to ensure constant latency. Dirac supports lossy and lossless compression modes.
Dirac employs wavelet compression, instead of the discrete cosine transforms used in most older compression formats. Dirac is one of several projects attempting to apply wavelets to video compression. Others include Rududu, Snow, RedCode and Tarkin. Wavelet compression is also used in the JPEG 2000 and PGF compression standards for photographic images.
Dirac can be used in various container formats (e.g., AVI, Ogg, MKV). It was registered for the use in container formats based on the ISO base media file format (MPEG-4 Part 12; e.g., MP4). It was also registered for use in MPEG-2 transport stream.
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.
