About formats

HCOM is a Huffman-coded audio format from the early Macintosh era, designed to shrink digitized sound for distribution on floppy disks and bulletin board systems when storage was precious and modems were slow. The encoder takes 8-bit unsigned PCM input, computes a frequency table of sample-delta values, and builds an optimal Huffman tree that replaces common deltas with short bit sequences. Compression ratios of 2:1 or better were typical for speech recordings, a meaningful saving when a 3.5-inch floppy held only 800 KB. Files were distributed as Macintosh resource forks and played through utilities like SoundApp and the BinHex ecosystem that defined Mac software exchange in the late 1980s. The format supported sample rates up to 22.255 kHz, matching the output capabilities of original Macintosh sound hardware. Tools such as SoX retain HCOM decoding support, ensuring that archived recordings remain accessible decades later. HCOM holds three practical advantages for preservation work: lossless compression that recovers the original samples exactly, a self-contained Huffman table embedded in each file for dependency-free decoding, and historical prevalence across thousands of vintage Mac sound archives.

PAF (Paris Audio File) is the native audio format of the Ensoniq PARIS (Professional Audio Recording Integrated System) digital audio workstation, developed by Ensoniq in the late 1990s. PARIS was a hardware/software DAW that earned a loyal following among recording engineers for its warm analog-like sound and reliable operation, with PAF serving as its primary working file container. The format stores uncompressed PCM audio at 16-bit or 24-bit resolution and standard professional sample rates (44.1, 48, and 96 kHz), preserving full fidelity without lossy compression. PAF uses a straightforward binary layout — a compact header followed by interleaved sample data — enabling efficient real-time read and write during recording sessions. One notable advantage is support for both big-endian and little-endian byte ordering, reflecting the PARIS system's cross-platform roots on Mac and PC. After Ensoniq's acquisition by E-mu Systems and then Creative Technology, the PARIS DAW was discontinued, but PAF files remain important for studios with archived projects in this format. Tools like SoX and libsndfile can read and convert PAF files, ensuring long-term accessibility.

Frequently Asked Questions

What is PAF?

PAF is a variant of the PARIS Audio File format associated with Ensoniq PARIS digital recording systems from the late 1990s.

How does PAF differ from FAP?

Both are PARIS Audio File variants. PAF and FAP differ in byte ordering conventions but serve the same Ensoniq PARIS ecosystem.

Why convert HCOM to PAF?

For vintage Ensoniq PARIS projects or audio preservation work that requires audio in the specific PAF format variant.

What handles PAF files?

SOX is the main modern tool for PAF. Original PARIS hardware and software work with PAF natively.

Is the conversion secure?

HCOM files are deleted after conversion. PAF results are automatically removed from servers within 24 hours.
