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.

Initial release: 1992
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 SNDT to WVE?

SNDT audio is inaccessible without specialized vintage tools. Psion WVE is the audio format for Psion PDAs — necessary when transferring recordings to or from these devices.

Which apps support WVE?

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

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 WVE output are protected throughout the process.

Can I convert multiple SNDT recordings at once?

Yes — upload several SNDT files and convert them all to WVE 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.
