About formats

FAP is a byte-swapped variant of the PAF (Paris Audio File) format associated with the Ensoniq PARIS digital audio workstation, a recording environment popular among project-studio engineers in the late 1990s. Where standard PAF stores sample data in big-endian order, FAP reverses the byte layout for little-endian architectures, enabling direct memory mapping on Intel-based processors without a runtime byte-swap penalty. The underlying payload is uncompressed linear PCM at up to 24-bit depth and 96 kHz sampling, preserving full studio-grade fidelity. Because there is no lossy coding stage, recordings survive unlimited edit cycles with zero generational loss — a critical property during tracking and mixing. The SoX command-line utility maintains read/write support for FAP, making it the most accessible tool for converting legacy PARIS sessions to modern formats. Despite its niche origins, FAP demonstrates solid engineering: the header is minimal and deterministic, eliminating ambiguity that sometimes plagues chunk-based containers. Advantages include bit-perfect audio preservation, fast I/O on x86 hardware due to native byte order, and straightforward interoperability with raw PCM tools.

Initial release: 1998
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.

Frequently Asked Questions

Why convert FAP to SNDT?

Since FAP has niche digital audio workstation format with no modern support, switching to SNDT provides basic audio storage for legacy systems.

How do I open a SNDT audio?

You can open SNDT with SoX and vintage DOS audio utilities.

Will I lose audio quality converting FAP to SNDT?

Converting to SNDT is lossless — the audio quality in the SNDT output will be identical to the original FAP recording.

Can I convert FAP to SNDT on any device?

Yes — the converter runs entirely in your browser, so it works on Windows, macOS, Linux, and mobile devices alike.

Can I convert multiple FAP recordings at once?

Yes — upload several FAP recordings simultaneously and they will all be converted to SNDT in parallel, saving you time.

Does FAP to SNDT conversion cost anything?

Standard conversions are available at no cost. Paid plans unlock higher limits and faster processing for heavy usage.
