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.

GSM 06.10 (Full Rate) is the foundational speech codec of the Global System for Mobile Communications standard, ratified by ETSI in 1991 and deployed across hundreds of cellular networks worldwide. Operating at a fixed 13 kbit/s, the algorithm applies Regular Pulse Excitation with Long-Term Prediction (RPE-LTP) to compress 20 ms frames of 8 kHz mono speech into just 33 bytes each. This approach models the vocal tract as a linear predictive filter, encodes the excitation signal, and leverages pitch periodicity for further reduction — tuned to deliver intelligible voice under the bandwidth constraints of early digital mobile channels. The codec powers not only GSM telephony but also many VoIP applications, voicemail systems, and IVR platforms that benefit from its low bitrate. Three concrete advantages stand out. First, extraordinary compression: one minute of speech fits in roughly 100 KB, enabling efficient storage and transmission. Second, universal tooling — libraries such as libgsm and SoX handle encoding and decoding on every major platform. Third, a royalty-free patent landscape that has encouraged adoption across open-source telephony projects like Asterisk and FreeSWITCH.
Initial release: 1991

Frequently Asked Questions

What is the benefit of converting PAF to GSM?

PAF is a discontinued DAW format with zero modern player support. Converting to GSM gives you standard mobile telephony codec.

What programs can play GSM?

You can open GSM with VLC, SoX, Audacity, and GSM-compatible telephony tools.

Does PAF to GSM conversion affect quality?

Since PAF is already a low-quality telephony format, converting to GSM typically improves accessibility without meaningful further loss.

Does this converter work on mobile devices?

Absolutely. Since conversion happens in the browser, any device with internet access and a modern browser will work.

How long does PAF to GSM conversion take?

Most conversions finish within seconds. Processing time depends on recording length, but the cloud-based engine handles it quickly.

What if my PAF recording is very long?

The converter handles recordings of various lengths. For very large or numerous files, premium plans provide extended capacity.
