Settings

The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the Vorbis encoder audio quality level. The scale is non-linear. The "Auto" mode produces roughly 112 kbps bitrate and is good in most cases.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

prc

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.

ogg

OGG Vorbis is an open, royalty-free lossy audio codec inside the Ogg container format, both developed by the Xiph.Org Foundation. Vorbis was designed as a patent-free alternative to MP3 and AAC, using modified discrete cosine transform (MDCT) coding with variable bitrate encoding that adapts to signal complexity per frame. Blind listening tests have consistently shown Vorbis delivering perceptual quality matching or exceeding MP3, especially in the 96-192 kbps range. The format supports sample rates from 8 kHz to 192 kHz and 1 to 255 channels, covering everything from mono voice to surround mixes. A standout advantage is the complete absence of licensing fees — game developers, streaming platforms, and hardware makers can implement Vorbis without royalty concerns. Spotify relied on Vorbis for years as its primary streaming codec for exactly this reason. The format also handles quality degradation at low bitrates more gracefully than many competitors, which is why it remains popular in video games where storage is tight and thousands of sound effects compete for space. VLC, Firefox, Chrome, and Android all provide native Vorbis decoding.

Frequently Asked Questions

Why convert PRC to OGG?

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

What applications open OGG files?

Browsers, VLC, Android, and Linux players can handle OGG files. Most are available as free downloads for major operating systems.

How is the OGG audio quality?

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

How fast is the conversion?

PRC files are typically compact. The conversion to OGG completes in just a few seconds on our cloud servers.

Are my files kept private?

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