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.
The Waveform Audio file format associated with the .wav filename extension was a format developed through collaboration between Microsoft and IBM. It is an extension of the RIFF and was first released in 1991. It is one of the earliest standards used for encoding audio bit streams on personal computers. It is typically used for storing uncompressed raw audio files on the Microsoft Windows platform, however it enjoys cross platform support on Macintosh and Linux and does have support for compressed audio. Because of the relatively large file sizes of uncompressed .wav files, the WAVE format in unpopular for file distribution over limited bandwidth computer networks including the internet.
FreeFileConvert uses tuned encoding for 3GP to WAV 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 WAV 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 WAV 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.
Bit stream encoding in the WAVE file format is achieved using the linear pulse code modulation format. It has three main data blocks and one to many number of wave chunks identified as the chunk ID, chunk size, wave ID, and finally the format information and the sampled data. Data storage is based on the little endian byte order.
