About formats

OGA is the audio-only file extension within the Ogg container framework maintained by the Xiph.Org Foundation. While .ogg traditionally served as a catch-all extension for any Ogg-encapsulated stream, the introduction of .oga in 2007 brought clarity by explicitly signaling that a file contains only audio data. Under the hood, OGA files can carry audio encoded with Vorbis, FLAC, Speex, or Opus — the container is codec-agnostic, serving as a transport wrapper with support for chained logical bitstreams and granule-based seeking. One benefit of OGA is interoperability: applications that encounter the .oga extension can optimize for audio-only playback without probing for video tracks, resulting in faster load times and lower memory usage. Because the Ogg container and its associated codecs are entirely open-source and royalty-free, OGA avoids the patent licensing complexities that affect proprietary formats. The format supports Vorbis comment metadata for tagging artist, album, and track information in a standardized way. OGA plays natively in Firefox, Chromium-based browsers, VLC, and most Linux desktop environments, making it a practical choice for web audio distribution and archival workflows.
Initial release: 2007
CVS is a telephony audio encoding based on Continuously Variable Slope Delta modulation, representing voice through a 1-bit delta scheme where step size adapts to track input amplitude. Developed within CCITT (now ITU-T) standards during the 1970s, CVS encodes by comparing each sample to the previous one and outputting a single bit — up or down — with slope magnitude adjusting based on recent bit patterns. This yields extremely low bit rates, typically 16 kbps at 8 kHz sampling, efficient for narrowband voice over constrained channels. CVS files store signed delta-encoded data and are commonly processed using tools like SoX. A significant advantage is bandwidth economy: the 1-bit-per-sample approach demands minimal transmission capacity, essential for military radio links and early digital telephone infrastructure. The adaptive slope mechanism also prevents overload distortion on rapidly changing signals while keeping granular noise acceptable during quiet passages. Though modern wideband codecs have superseded CVS, it retains historical importance and niche utility in legacy telephony and embedded communication devices.
