About formats

AAC (Advanced Audio Coding) is the successor to MP3, standardized by ISO/IEC as part of the MPEG-2 and later MPEG-4 specifications. Designed collaboratively by Fraunhofer, Dolby, Sony, Nokia, and AT&T, AAC delivers superior sound quality at equivalent or lower bit rates — a 96 kbps AAC stream generally matches a 128 kbps MP3 file in perceptual quality. The codec leverages a modified discrete cosine transform combined with advanced psychoacoustic modeling and temporal noise shaping. AAC serves as the default audio format for Apple's ecosystem (iTunes, iPhone, iPad), YouTube, and many streaming services. Its first advantage is excellent compression efficiency — high-fidelity audio using significantly less storage and bandwidth. Second, the format supports sample rates from 8 kHz to 96 kHz and up to 48 channels, suiting everything from voice calls to surround sound. Third, broad industry adoption by Apple and others ensures that virtually every modern device, browser, and media player handles AAC content natively without additional plugins.
Initial release: 1997
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.
