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.

SOU is a raw audio format designation that functions as an alias for unsigned 8-bit PCM data (u8) in the SoX audio processing framework. Files with the .sou extension contain headerless, uncompressed audio samples stored as unsigned 8-bit integers — each byte represents a single amplitude value from 0 to 255, with 128 as the silence midpoint. Because there is no header, playback parameters such as sample rate and channel count must be specified externally. The default assumption is typically mono at 8000 Hz, though the data can represent any rate the recording hardware supported. The u8 encoding that SOU aliases is one of the simplest possible digital audio representations, predating structured audio containers like WAV and AIFF. Raw unsigned PCM was commonly produced by early sound cards and digitizers in the late 1980s and early 1990s, when storage constraints and limited processing power made headerless formats a practical choice. One advantage is absolute simplicity: SOU files can be read by any program capable of basic file I/O, with no parsing of container structures or metadata decoding required — useful for embedded systems, hardware diagnostics, and educational contexts where audio fundamentals are being explored. The format's minimal overhead also means that conversion to any modern container is lossless and instantaneous, since the raw PCM samples can be wrapped in a WAV or AIFF header without any transcoding.

Frequently Asked Questions

Why convert OGA to SOU?

SOU provides raw unsigned PCM. Convert OGA when your application requires basic, headerless audio data.

What programs can open SOU files?

SoX and raw audio editors can open SOU files. It is a simple format for basic audio data.

How long does OGA to SOU conversion take?

Audio conversions typically complete within seconds. Larger files may take a bit longer depending on size and server load.

Are my files safe when converting OGA to SOU?

Completely. Source audio is erased right after processing, and converted SOU files are purged within 24 hours.

Can I convert OGA to SOU on my phone?

Yes — the converter runs in any mobile browser. Works on both iOS and Android without installing an app.
