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 number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

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.

w64

W64 (Wave64) is a 64-bit audio container originally designed by Sonic Foundry — creators of Sound Forge — and later maintained by Sony after acquiring Sonic Foundry's desktop software division in 2003. The format directly addresses the 4 GB file-size ceiling imposed by Microsoft's 32-bit RIFF/WAV specification, a limitation that becomes problematic during long recording sessions, multi-channel captures, or high-sample-rate productions. W64 achieves this by extending chunk identifiers and size fields to 64 bits, using GUIDs instead of four-character codes. This structural change permits files to reach sizes measured in exabytes, effectively removing any practical storage constraint. The format supports arbitrary sample rates, bit depths, and channel configurations, making it well suited for film scoring, live concert recording, and scientific data acquisition. Sound Forge, Audacity, and other professional digital audio workstations provide native W64 support for seamless import and export. For engineers and producers who routinely work with long-form, high-fidelity material, W64 offers the reliability and simplicity of WAV without the frustrating size restriction.

Frequently Asked Questions

Why convert PRC to W64?

PRC is locked to obsolete Psion PDAs. W64 makes your recordings accessible on modern devices and standard audio software.

What applications open W64 files?

Sound Forge, Vegas Pro, and Audacity can handle W64 files. Most are available as free downloads for major operating systems.

Is the conversion lossless?

Yes. W64 stores audio without compression loss. Every sample from the PRC source is perfectly preserved in the W64 output.

How fast is the conversion?

Both formats produce manageable file sizes. The PRC to W64 conversion finishes almost instantly on our infrastructure.

Are my files kept private?

Your PRC files are erased after conversion completes. W64 downloads are purged from our servers within 24 hours automatically.
