What is a 3GP file?
The 3GP format is a multimedia container defined by the 3rd Generation Partnership Project (3GPP) primarily for 3G UMTS multimedia services on GSM-based mobile networks. Ideally suited for mobile bandwidth limitations, it encapsulates video streams encoded in MPEG-4 Part 2, H.263, or H.264 (MPEG-4 AVC) and audio in AMR-NB, AMR-WB, or AAC formats. The structure is based on the ISO base media file format (MPEG-4 Part 12), prioritizing high compression ratios over high-fidelity playback to facilitate Multimedia Messaging Service (MMS) transmission.
How to open a 3GP file
Most modern mobile operating systems (Android, iOS) handle 3GP natively. On desktop systems, Microsoft Windows Media Player and Apple QuickTime provide varying degrees of support depending on the specific video codec used within the container. If native players fail to render the AMR audio track, users should utilize the VLC media player or MPlayer, which contain built-in libraries for decoding 3GPP-compliant streams.

What is a FLAC file?
The Free Lossless Audio Codec (FLAC) is an open-source audio coding format developed by the Xiph.Org Foundation that compresses digital audio without any loss of data (bit-perfect preservation). It employs linear prediction and Rice coding (Golomb-Rice) rather than the perceptual psychoacoustic modeling used in MP3 or AAC. The format structure consists of the 'fLaC' stream marker, metadata blocks (Streaminfo, Vorbis comments for tags, Seekpoints), and audio frames, typically achieving compression ratios of 50-70% compared to raw PCM WAV files.
How to open a FLAC file
FLAC enjoys extensive native support on modern platforms, including Windows 10/11, Android, and macOS (starting with macOS High Sierra). For older systems or advanced playback control, software such as Foobar2000 (Windows) or Vox (macOS) is recommended. The VLC media player is a universal solution for all operating systems, handling FLAC streams and associated metadata seamlessly.
