Settings

Set the Opus audio bitrate per channel. If set to "Custom", the Opus audio codec supports up to 256 kbit/s per channel with a recommended range of ≥64 kbps.
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.

wve

WVE is the audio format native to the Psion Series 3 family of personal digital assistants, released by British company Psion PLC beginning in September 1991. These clamshell PDAs included a built-in voice recorder, and all dictation functionality relied on WVE files to store captured sound. Each file begins with the ASCII signature "ALawSoundFile**" followed by a minimal header, then raw A-law encoded audio sampled at 8 kHz — a rate inherited from digital telephony standards. At 8000 bytes per second, a one-minute recording occupies just 480 KB, which was essential given that Psion devices stored data on SRAM cards typically ranging from 128 KB to 2 MB. The A-law encoding provides reasonable speech clarity within these tight storage constraints, prioritizing intelligibility over high-fidelity reproduction. WVE files can be converted to WAV or other modern formats using SoX, Awave Studio, or specialized Psion file utilities. While the format is firmly a product of early-1990s handheld computing, it holds historical significance as one of the first audio recording formats designed for pocket-sized consumer devices. Collectors and researchers studying mobile computing history occasionally encounter WVE files when recovering data from legacy SRAM media.

opus

Opus is a versatile, open audio codec standardized by the IETF as RFC 6716 in 2012. It fuses two coding approaches — SILK for speech and CELT for music — into one algorithm that blends between them based on content type and bitrate. This hybrid design lets Opus outperform virtually every other codec across a wide range of uses: low-latency voice at 6 kbps, high-fidelity music at 128 kbps, and everything in between. It supports bitrates from 6 to 510 kbps, sample rates up to 48 kHz, and frame sizes as small as 2.5 ms, giving it the lowest algorithmic latency of any mainstream audio codec. Three advantages make Opus especially compelling. It is completely royalty-free and open-source, removing licensing barriers that hold back proprietary codecs. It achieves transparent quality at roughly half the bitrate of MP3 and beats AAC at equivalent rates. And its low latency makes it the mandatory codec for WebRTC, so every modern browser ships with an Opus decoder. WhatsApp, Discord, Zoom, and YouTube all rely on Opus for real-time audio.

Frequently Asked Questions

Why convert WVE to OPUS?

Opus is the most advanced open codec. Converting WVE produces the best quality at the lowest file sizes.

What can open OPUS files?

Chrome, Firefox, Edge, VLC, foobar2000, and Android play Opus.

What is the WVE format?

WVE is the native audio format of Psion PDA devices (Series 3, 5, Revo). It stores 8-bit A-law encoded audio — a legacy from the EPOC operating system.

Can modern systems play WVE?

SoX and PsiWin on Windows can process WVE files. Standard media players do not support it — conversion is the easiest path to playback.

Can I convert multiple WVE files?

Yes. Upload several Psion recordings and batch-convert them all at once — efficient for archiving an entire PDA audio library.
