About formats

AVCHD (Advanced Video Coding High Definition) is a high-definition recording format jointly developed by Sony and Panasonic for use in consumer and semi-professional camcorders. Announced in 2006, the format records H.264/MPEG-4 AVC video at resolutions up to 1920x1080 with Dolby Digital or uncompressed LPCM audio, stored within an MPEG-2 transport stream container. AVCHD was designed to work with a variety of recording media, including optical discs, hard disk drives, and solid-state memory cards, giving camera manufacturers flexibility in hardware design. The use of H.264 compression delivers superior image quality at lower bit rates compared to earlier recording standards like DV and MPEG-2, enabling longer recording times on the same storage capacity. AVCHD supports progressive and interlaced scanning modes, accommodating both cinematic and broadcast-style shooting. The directory structure follows a strict specification that includes playlist files for navigating recorded clips, making it compatible with Blu-ray players when recorded to compatible disc media. An enhanced version, AVCHD 2.0, added support for 1080/60p progressive recording and 3D stereoscopic video. The format remains widely used in the camcorder market and continues to be supported by major video editing applications.

SNDR is the audio file format produced by Sounder, an early MS-DOS sound recording and playback utility from the early 1990s. Before Windows brought multimedia to the mainstream, Sounder was among a handful of DOS programs that let PC users capture and play audio through rudimentary hardware — often the PC speaker itself or early 8-bit sound cards. The format stores 8-bit unsigned PCM samples without any file header, relying on application defaults to determine playback parameters. Sample rates were typically low (4000 to 11025 Hz), reflecting hardware limits and storage costs when a 20 MB hard drive was considered generous. One practical advantage was absolute minimalism — with zero overhead bytes, every bit of the file was audio data, which mattered when storage was measured in kilobytes. The format could be piped directly to sound hardware without parsing, making real-time playback feasible on slow processors. Despite its simplicity, SNDR holds a place in computing history as one of the formats that brought digital audio to ordinary PCs. Files from this era occasionally surface in retrocomputing archives. SoX and ffmpeg can interpret SNDR files given the correct parameters, enabling preservation of early digital audio recordings.
