Convert AWB to M4R

AWB to M4R Conversion Software converts AWB files to M4R iPhone Ringtone and keeps ID3 tag. The M4R is ringtone file used by iPhone. With the AWB to M4R Conversion Software, you could create your own ringtone for your iPhone. You can also convert a part of source AWB to M4R ringtone. The converter is a professional audio conversion software that also supports common format such as AU, MPA, M4B (MPEG-4 audiobook), MMF, AAC for iPod/iPhone/iPad/iTunes/DSi, OGG, AMR, AAC, etc. It could convert QCP to AC3, AWB to AAC, VOB to MMF, CDA to MKA, WMA to OGG, MP4 to M4R (iPhone ringtone), and so on.

The software supports batch conversion. It is full compatible with both 32-bit and 64-bit editions Windows 10/8/7/Vista/XP/2000.

AWB to M4R Conversion Software is compatible with Windows 10/8/7/Vista/XP/2008/2003/2000

What is AWB?
Adaptive Multi-Rate Wideband (AMR-WB) is a patented speech coding standard developed based on Adaptive Multi-Rate encoding, using similar methodology as Algebraic Code Excited Linear Prediction (ACELP). AMR-WB provides excellent speech quality due to a wider speech bandwidth of 50-7000 Hz compared to narrowband speech coders which in general are optimized for POTS wireline quality of 300-3400 Hz.

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.

What is M4R?
M4R is the standard file format for Apple iPhone ringtones. The M4R is encoded with Advanced Audio Coding (AAC). The AAC is a standardized, lossy compression and encoding scheme for digital audio. AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications.
