Originally being developed by a Third Generation Partnership Project II, it's used in the third generation mobile phones, 3g2 is basically used as an audio as well as video file format. It is a relatively similar file format to 3gp with some advancements as well as limitations. Specifically, the 3g2 format is for CDMA based mobile phones rather than GSM-based phones, this format is used in fourth generation phones as well. Basically, it is for video viewing, it is also used for transferring photos and videos through the internet. Based on the standards of MPEG-4, it is developed in the light to play the media and to deliver it through the internet connection over high speed.
First released in 1995 and developed by the Fraunhofer Society, the mp3 audio format is arguably one of the most recognizable audio file format that ever existed. This digital audio encoding format hails from the lossy data compression algorithm family. The format enjoys widespread support and compatibility with most handheld music players, smartphones, computers, and in car stereos most of which have native support for the format. It is also a popular format used for distribution of audio files over computer networks such as the internet. Free mp3 encoders such as LAME and audacity give authors the tools necessary to create .mp3 files.
FreeFileConvert uses tuned encoding for 3G2 to MP3 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload 3G2 files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized MP3 results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent MP3 audio with dependable progress tracking.
3g2 format has a contrasting similarity with MP-4 and is a more simplified version of the complex MPEG-4. It is actually designed to accommodate in the cellular phones, its bandwidth requirements are reduced in order to reduce the storage required. It stores and streams the videos and audios as done by the 3gP format. However, the audio streams that are stored by the 3g2, are in the extensions such as EVRC-B, SMV, EVRC-WB, VMR-WB, EVRC, 13k or QCELP.
The MP3 format compression algorithm works through perceptual coding. A technique in which audio artifacts outside the auditory range of the average human, are reduced or 'cancelled out'. The result is a near perfect replication of the original audio sample at a compression ratio of 11 to 1 at 128 kilobits per second. Audio quality can be controlled by such factors as the bit rate, sample rate, among other features. But bits rates being the main determinant of audio quality can be adjusted between the typical range from 128 kb/s to as high as 320kb/s.
