Music Research

IRCAM is standard in computer music research — extracting from HEVC produces audio for academic analysis.

Fast Extraction

Audio extraction skips video processing — your HEVC-to-IRCAM conversion finishes in seconds, not minutes.

Secure Files

HEVC uploads are erased immediately after conversion. IRCAM outputs are deleted within 24 hours.

About formats

HEVC (High Efficiency Video Coding), also designated as H.265 and MPEG-H Part 2, is a video compression standard developed jointly by the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. Approved in January 2013, HEVC was designed as the successor to H.264/AVC with the primary goal of doubling the compression efficiency — achieving equivalent visual quality at roughly half the bit rate. The standard accomplishes this through larger coding tree units of up to 64x64 pixels, more sophisticated motion prediction with 35 directional intra modes, advanced sample adaptive offset filtering, and parallel processing tools including tiles and wavefront parallel processing. HEVC supports resolutions from 320x240 up to 8192x4320 (8K UHD), making it future-proof for emerging display technologies. The codec is widely adopted in broadcasting, where it enables efficient delivery of 4K and HDR content over bandwidth-constrained channels, as well as in video conferencing and surveillance applications. Apple adopted HEVC as the default recording format for iOS devices beginning with iOS 11, dramatically expanding its consumer reach. Despite technical superiority over H.264, a complex and fragmented patent licensing landscape has driven interest in royalty-free alternatives like AV1, though HEVC remains deeply embedded in broadcast infrastructure and consumer electronics worldwide.

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.

Frequently Asked Questions

Why convert HEVC to IRCAM?

IRCAM is the format from the Institut de Recherche et Coordination Acoustique/Musique.

How do I open IRCAM files?

IRCAM tools, Csound, SoX, and Audacity.

Is only the audio extracted?

Yes — the video portion of the HEVC file is discarded. Only the audio track is saved as IRCAM.

Can I convert multiple files?

Upload several HEVC videos at once and extract IRCAM audio from each simultaneously in a single batch.

Are my uploads secure?

HEVC files are deleted immediately after conversion. IRCAM outputs are removed from our servers within 24 hours.
