Convert MPEG to M4R

MPEG to M4R Conversion Software converts MPEG files to M4R iPhone Ringtone and keeps ID3 tag. The M4R is ringtone file used by iPhone. With the MPEG to M4R Conversion Software, you could create your own ringtone for your iPhone. You can also convert a part of source MPEG to M4R ringtone. The converter is a professional audio conversion software that also supports common format such as M4A (MPEG-4 audio), AIFF, AU, MPA, AAC for iPod/iPhone/iPad/iTunes/DSi, MMF, MKA, M4R (iPhone ringtone), etc. It could convert WAV to AAC, AC3 to MPA, QCP to VOC, AU to MP2, MPE to M4R (iPhone ringtone), 3G2 to AAC, 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.

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

What is MPEG?
The Moving Picture Experts Group (MPEG) was formed by the ISO to set standards for audio and video compression and transmission. Its first meeting was in May 1988 in Ottawa, Canada. As of late 2005, MPEG has grown to include approximately 350 members per meeting from various industries, universities, and research institutions. MPEG's official designation is ISO/IEC JTC1/SC29 WG11.

The MPEG standards consist of different Parts. Each part covers a certain aspect of the whole specification. The standards also specify Profiles and Levels. Profiles are intended to define a set of tools that are available, and Levels define the range of appropriate values for the properties associated with them. MPEG has standardized the following compression formats and ancillary standards:

MPEG-1: The first compression standard for audio and video. It was basically designed to allow moving pictures and sound to be encoded into the bitrate of a Compact Disc. To meet the low bit requirement, MPEG-1 downsamples the images, as well as uses picture rates of only 24-30 Hz, resulting in a moderate quality. It includes the popular Layer 3 (MP3) audio compression format.
MPEG-2: Transport, video and audio standards for broadcast-quality television. MPEG-2 standard was considerably broader in scope and of wider appeal - supporting interlacing and high definition. MPEG-2 is considered important because it has been chosen as the compression scheme for over-the-air digital television ATSC, DVB and ISDB, digital satellite TV services like Dish Network, digital cable television signals, SVCD, and DVD.
MPEG-3: Developments in standardizing scalable and multi-resolution compression which would have become MPEG-3 were ready by the time MPEG-2 was to be standardized; hence, these were incorporated into MPEG-2 and as a result there is no MPEG-3 standard. MPEG-3 is not to be confused with MP3, which is MPEG-1 Audio Layer 3.
MPEG-4: MPEG-4 uses further coding tools with additional complexity to achieve higher compression factors than MPEG-2. In addition to more efficient coding of video, MPEG-4 moves closer to computer graphics applications. In more complex profiles, the MPEG-4 decoder effectively becomes a rendering processor and the compressed bitstream describes three-dimensional shapes and surface texture. MPEG-4 also provides Intellectual Property Management and Protection (IPMP) which provides the facility to use proprietary technologies to manage and protect content like digital rights management. Several new higher-efficiency video standards (newer than MPEG-2 Video) are included (an alternative to MPEG-2 Video), notably:

MPEG-4 Part 2 (or Simple and Advanced Simple Profile) and
MPEG-4 AVC (or MPEG-4 Part 10 or H.264). MPEG-4 AVC may be used on HD DVD and Blu-ray discs, along with VC-1 and MPEG-2.

In addition, the following standards, while not sequential advances to the video encoding standard as with MPEG-1 through MPEG-4, are referred to by similar notation:

MPEG-7: A multimedia content description standard.
MPEG-21: MPEG describes this standard as a multimedia framework.

Moreover, relatively more recently than other standards above, MPEG has started following international standards; each of the standards holds multiple MPEG technologies for a way of application. For example, MPEG-A includes a number of technologies on multimedia application format.

MPEG-A: Multimedia application format.
MPEG-B: MPEG systems technologies.
MPEG-C: MPEG video technologies.
MPEG-D: MPEG audio technologies.
MPEG-E: Multimedia Middleware.

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.
