About formats

SNDT is the audio format associated with Sndtool, an early MS-DOS sound utility from the early 1990s that appeared alongside the spread of Sound Blaster cards in PCs. Unlike the headerless Sounder format, SNDT files include a brief header with the sample rate and data length — a meaningful improvement that let playback software determine timing automatically. Audio data is stored as 8-bit unsigned PCM, typically at 8000 to 22050 Hz in mono. Sndtool functioned as a simple waveform recorder and player, often distributed as shareware or bundled with sound card drivers. A key advantage over competing DOS audio formats was this self-describing header, which eliminated the guesswork of playing unfamiliar files — a real problem before standardized multimedia frameworks existed. The format was also efficient to decode, requiring no decompression and minimal CPU overhead on the 286 and 386 processors of the time. SNDT files served as building blocks for early PC games and multimedia presentations, where developers needed reliable audio across the limited Sound Blaster hardware ecosystem. Today, SNDT survives in retro software archives and is supported by SoX for conversion to modern 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.

Frequently Asked Questions

Why convert SNDT to PRC?

SNDT audio is inaccessible without specialized vintage tools. PRC is the Psion audio format — necessary when interfacing with Psion PDA devices or compatible software.

Which apps support PRC?

Open PRC with SoX or Psion-compatible audio tools. These tools handle the format natively and provide reliable playback.

Can I convert multiple SNDT recordings at once?

Yes — upload several SNDT files and convert them all to PRC simultaneously. Batch conversion saves significant time on collections.

Will audio quality degrade during conversion?

Quality depends on the target codec. Lossless formats keep every sample from your SNDT source. Lossy codecs apply minimal compression.

Does the converter work with damaged recordings?

The converter reads whatever audio data is available in the SNDT file. Severely corrupted sections may not transfer, but valid data converts.

Is my data encrypted during transfer?

All uploads and downloads use encrypted HTTPS connections. Your SNDT audio and the resulting PRC output are protected throughout the process.
