About formats

PRC is an audio file format associated with Psion handheld organizers, particularly the Series 3 and Series 5 lines from the 1990s. These pocket computers included built-in microphones and basic voice recording capabilities, storing captured audio in the PRC container. The encoding is typically ADPCM-based (Adaptive Differential Pulse-Code Modulation), balancing file size against audio intelligibility given the severe storage constraints of early PDAs — the original Psion Series 3 had just 256 KB of RAM doubling as storage. PRC audio is generally mono at low sample rates (often 8 kHz), optimized for speech rather than music. One advantage was tight integration with the EPOC operating system (later evolving into Symbian), letting users embed voice notes directly in agenda entries and database records. The compact file sizes — a minute of speech consumed only a few kilobytes — made it feasible to store dozens of memos on devices with minimal memory. While PRC audio is a legacy format today, conversion tools exist for extracting recordings from archived Psion devices, which remain collectible among retro computing enthusiasts.

FAP is a byte-swapped variant of the PAF (Paris Audio File) format associated with the Ensoniq PARIS digital audio workstation, a recording environment popular among project-studio engineers in the late 1990s. Where standard PAF stores sample data in big-endian order, FAP reverses the byte layout for little-endian architectures, enabling direct memory mapping on Intel-based processors without a runtime byte-swap penalty. The underlying payload is uncompressed linear PCM at up to 24-bit depth and 96 kHz sampling, preserving full studio-grade fidelity. Because there is no lossy coding stage, recordings survive unlimited edit cycles with zero generational loss — a critical property during tracking and mixing. The SoX command-line utility maintains read/write support for FAP, making it the most accessible tool for converting legacy PARIS sessions to modern formats. Despite its niche origins, FAP demonstrates solid engineering: the header is minimal and deterministic, eliminating ambiguity that sometimes plagues chunk-based containers. Advantages include bit-perfect audio preservation, fast I/O on x86 hardware due to native byte order, and straightforward interoperability with raw PCM tools.

Frequently Asked Questions

Why convert PRC to FAP?

PRC is locked to obsolete Psion PDAs. FAP makes your recordings accessible on modern devices and standard audio software.

What applications open FAP files?

SOX and PARIS hardware/software can handle FAP files. Most are available as free downloads for major operating systems.

How is the FAP audio quality?

FAP provides good quality at standard settings. The output clarity depends on the original PRC recording quality.

How fast is the conversion?

Processing is fast — PRC files are lightweight and FAP encoding completes in seconds on our server hardware.

Are my files kept private?

Uploaded PRC files are deleted immediately after conversion. FAP results are automatically erased from our servers within 24 hours.
