The 3GP file format and its associated filename extension .3gp is an audio, video, and text container developed by the 3rd generation partnership project. The target market for the 3gp file format is 3G enabled UMTS mobile phones through associated UMTS multimedia services. Though mobile devices operating on high speed networks are the intended hardware associated with playing .3gp files, many PC codec packs exist which grant compatibility for .3gp playback. The format has a basic profile in which files of this format do not reference any external media sources and support for audio, video, and text is limited to a single track.
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 3GP to MP3 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload 3GP 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.
The 3gp format is standardized in the ETSI technical specification in which support for it is implied in IMS, MMS, PSS, and MBMS carrier services. The format is based upon the ISO/IEC 14496-12-MPEG-4 part 12 standard. As such, video streams in the 3gp format can be encoded in mpeg-4 part 2 or mpeg-4 part 10. Audio streams can be encoded in AMR- narrow band, AMR-wide band, AAC-LC and others.
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.
