Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).

 

How to open an AMR file?

Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.

 

Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.

Flash Live Video (FLV) is, as the name suggests, a type of Flash video. It is a popular format that delivers high-quality, well-synchronized multimedia content, primarily over the Internet. It is also a media container, and as such, uses codecs to compress file size. FLV uses the open standard ISO/IEC 14496-12:2008, also known as the ISO base media file format, which offers the advantage of flexibility and independence.

 

How to open an FLV file?

By default, FLV opens in Adobe products, namely Animate Creative Cloud (Animate CC) and Flash. It opens best in Adobe Flash version 7 and above. FLV does not support chapters or subtitles, but it does support metadata tags.

 

Since FLV is based on an open standard, it can open in many non-Adobe products. Other programs in which FLV can open include VLC media player, Zoom Player, RealNetworks RealPlayer Cloud, Eltima Elmedia Player, and others.
