About formats

SND is a multi-platform audio file extension used across several computing ecosystems since the late 1980s. On Sun and NeXT workstations, .snd files follow the AU format structure — a header with magic number 0x2e736e64, data offset, encoding type, sample rate, and channel count, followed by raw audio. On MS-DOS PCs, the same .snd extension was used by early sound utilities like Sounder and SoundTool for simple 8-bit unsigned PCM recordings. Macintosh systems also employed .snd for sound resources embedded in the resource fork. Because the extension is shared across incompatible formats, audio processing tools typically inspect the file header to determine which variant they are handling: files beginning with the AU magic number are treated as Sun/NeXT audio, while headerless files are interpreted as raw PCM with assumed parameters. The Sun/NeXT variant supports multiple encodings including mu-law, A-law, 8-bit and 16-bit linear PCM, and ADPCM, making it versatile for both speech and general audio. One advantage of the AU-style SND is its self-describing header, which enables any compliant player to determine sample format and rate without external metadata. The MS-DOS SND variants hold historical value as artifacts of the era when Sound Blaster cards first brought digital audio to personal computers. SND files from all platforms can be processed and converted using SoX and other audio tools.
Initial release: 1988
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.

Frequently Asked Questions

Why convert SND to WVE?

SND recordings are not usable on Psion devices. WVE is the native audio format for Psion handheld computers and organizers.

How do I open WVE recordings?

Play WVE with SoX or Psion-compatible handheld device audio players.

Can I tweak audio parameters before conversion?

The converter allows you to configure sample rate, bit depth, and channel layout before producing the WVE output.

Does SND to WVE conversion preserve audio quality?

Quality preservation depends on the target. Lossless WVE keeps everything; lossy encoding trades minor quality for much smaller file sizes.

Can I convert multiple SND recordings to WVE at once?

Batch conversion is fully supported. Drop all your SND files at once and convert them to WVE together, saving time.

Is the SND to WVE conversion private?

Completely private. SND uploads are erased right after processing, and WVE downloads are purged from servers within 24 hours.
