Convert MP3 to M4R

MP3 to M4R Conversion Software converts MP3 files to M4R iPhone Ringtone and keeps ID3 tag. The M4R is ringtone file used by iPhone. With the MP3 to M4R Conversion Software, you could create your own ringtone for your iPhone. You can also convert a part of source MP3 to M4R ringtone. The converter is a professional audio conversion software that also supports common format such as WAV, M4A (MPEG-4 audio), AAC, MP3, VOC, MMF, FLAC, M4R (iPhone ringtone), etc. It could convert MPA to AC3, EVO to AMR, MPA to OGG, ADTS to M4A (MPEG-4 audio), AMV to MMF, M4V to MMF, 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.

What is MP3?
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a digital audio encoding format using a form of lossy data compression. It is a common audio format for consumer audio storage, as well as a de facto standard encoding for the transfer and playback of music on digital audio players. MP3's use of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners, but is not considered high fidelity audio by audiophiles. An MP3 file that is created using the mid-range bit rate setting of 128 kbit/s will result in a file that is typically about 1/10th the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality. The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people. This method is commonly referred to as perceptual coding. It internally provides a representation of sound within a short term time/frequency analysis window, by using psychoacoustic models to discard or reduce precision of components less audible to human hearing, and recording the remaining information in an efficient manner. This is relatively similar to the principles used by JPEG, an image compression format.

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.
