Ogg Vorbis Audio (OGA) is a multimedia container and compression file format for audio files. The name represents the basic functionality of OGA, as “Ogg” is the name of the container while “Vorbis” is the name of the compression mechanism. OGA is free, open-source, and unpatented.

 

How to open an OGA file?

VLC media player is the best choice for opening OGA files. Other programs that can open OGA files include Winamp and Xine.

 

OGA can open in Windows Media Player and DirectShow-based players, but only with the use of a DirectShow filter. However, if the player is not based on DirectShow, then the filter is not necessary.

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.
