M4R: the ringtone file used in Apple iOS
The M4R format is used in Apples mobile devices, mostly for storing ringtones. You can create an M4R file by converting other formats or downloading it from the official iTunes store. The sound conversion employs a special type of compression, which significantly reduces the file size. The advantages of this format make it ideal for iPhone owners. M4R is one of the constituents of the standardized MPEG-4 format. One of its strong points is that the high sound quality is fully preserved after compression.
True Audio (TTA): a free audio codec for audio compression
This is a free audio codec that enables compression without any losses. The True Audio format was developed by Russian specialists back in 2009. The main advantage of TTA is the highly efficient compression: up to 30% of the total volume. The original quality of the file is fully preserved. The encoding algorithm is implemented in real-time mode. The True Audio data format is simple and open; it is also suitable for lossless compression of multichannel files.
