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.

SNDT is the audio format associated with Sndtool, an early MS-DOS sound utility from the early 1990s that appeared alongside the spread of Sound Blaster cards in PCs. Unlike the headerless Sounder format, SNDT files include a brief header with the sample rate and data length — a meaningful improvement that let playback software determine timing automatically. Audio data is stored as 8-bit unsigned PCM, typically at 8000 to 22050 Hz in mono. Sndtool functioned as a simple waveform recorder and player, often distributed as shareware or bundled with sound card drivers. A key advantage over competing DOS audio formats was this self-describing header, which eliminated the guesswork of playing unfamiliar files — a real problem before standardized multimedia frameworks existed. The format was also efficient to decode, requiring no decompression and minimal CPU overhead on the 286 and 386 processors of the time. SNDT files served as building blocks for early PC games and multimedia presentations, where developers needed reliable audio across the limited Sound Blaster hardware ecosystem. Today, SNDT survives in retro software archives and is supported by SoX for conversion to modern formats.
