About formats

PAF (Paris Audio File) is the native audio format of the Ensoniq PARIS (Professional Audio Recording Integrated System) digital audio workstation, developed by Ensoniq in the late 1990s. PARIS was a hardware/software DAW that earned a loyal following among recording engineers for its warm analog-like sound and reliable operation, with PAF serving as its primary working file container. The format stores uncompressed PCM audio at 16-bit or 24-bit resolution and standard professional sample rates (44.1, 48, and 96 kHz), preserving full fidelity without lossy compression. PAF uses a straightforward binary layout — a compact header followed by interleaved sample data — enabling efficient real-time read and write during recording sessions. One notable advantage is support for both big-endian and little-endian byte ordering, reflecting the PARIS system's cross-platform roots on Mac and PC. After Ensoniq's acquisition by E-mu Systems and then Creative Technology, the PARIS DAW was discontinued, but PAF files remain important for studios with archived projects in this format. Tools like SoX and libsndfile can read and convert PAF files, ensuring long-term accessibility.

SLN (Signed Linear) is a headerless raw audio format storing 16-bit signed linear PCM samples at 8000 Hz mono, most closely associated with Asterisk — the open-source PBX framework developed by Digium (now Sangoma Technologies). Within Asterisk, SLN serves as the native internal audio representation: every codec transcoding operation passes through signed linear as an intermediate step. This makes SLN the backbone of Asterisk's codec translation architecture. The format contains nothing but raw samples — no headers, no metadata, no framing — so parameters must be known in advance. While this lack of self-description might seem limiting, it is actually an advantage in telephony where sample format is fixed by convention and every overhead byte matters across thousands of simultaneous channels. The 8000 Hz rate aligns with the G.711 standard for traditional telephony, capturing the full 300-3400 Hz voice band. Asterisk also supports extended variants (sln16, sln32, sln48) for wideband audio. SLN files require no decoding — just direct memory mapping — making them ideal for real-time mixing, conferencing, and prompt playback in high-density VoIP environments.

Frequently Asked Questions

Why should I switch from PAF to SLN?

PAF suffers from niche big-endian audio format no longer in active use. SLN offers VoIP system integration.

Which software opens SLN recordings?

You can open SLN with Asterisk PBX, SoX, and VoIP telephony systems.

Is there quality loss from PAF to SLN?

No quality is lost. SLN stores audio without additional compression, so your PAF recording carries over at full original fidelity.

Is PAF to SLN conversion available on all platforms?

It works on any platform — desktop or mobile. Just open your browser, upload the PAF recording, and convert to SLN.

Is my PAF audio kept private during conversion?

Your uploaded PAF recordings are deleted immediately after conversion. The resulting SLN outputs are removed within 24 hours.

Do I need to install anything for PAF to SLN?

No installation required. The converter runs entirely in your web browser — just upload, convert, and download.
