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.

IRCAM sound files originate from the Institut de Recherche et Coordination Acoustique/Musique — one of the world's foremost computer music laboratories, founded by composer Pierre Boulez in Paris. The format was created in the early 1980s to serve the research needs of IRCAM and has since been adopted by academic and artistic communities working at the intersection of science and sound. An IRCAM file begins with a 1024-byte header containing a magic number, sample rate, channel count, and an encoding type field that supports linear PCM (16/32-bit integer and 32-bit float), mu-law, and A-law variants. The header block also accommodates free-form annotation text, allowing researchers to embed experiment metadata directly in the audio file. Because the payload is uncompressed by default, recordings maintain full fidelity through successive analysis and resynthesis cycles — essential in psychoacoustic experimentation. Software such as Csound, libsndfile, and SoX reads and writes the format natively. Key advantages include a well-defined header that eliminates parsing ambiguity, support for floating-point samples essential in scientific DSP work, and deep roots in the computer music community ensuring continued tooling.
