About formats

IMA ADPCM (Adaptive Differential Pulse-Code Modulation) is a compact audio coding standard published by the Interactive Multimedia Association in 1992, addressing the need for a lightweight, royalty-free compression scheme suitable for early multimedia PCs and embedded devices. The algorithm encodes each sample as a 4-bit nibble representing the quantized difference from the previous sample, while an adaptive step-size table adjusts dynamically to track signal amplitude — delivering a fixed 4:1 compression ratio over 16-bit PCM. Decoding requires only an integer multiply-add per sample and a small lookup table, so even modest 1990s CPUs could decompress in real time without dedicated DSP. The format became deeply embedded in the multimedia landscape: Microsoft adopted it as a standard ACM codec for WAV files, game engines relied on it for sound effects, and telephony equipment used it for voice storage. Its advantages are enduring: predictable 4:1 size reduction simplifies buffer allocation in constrained environments, the decode path runs on 8-bit microcontrollers, and the open specification made IMA ADPCM one of the most broadly implemented audio codecs in computing history.
Initial release: 1992
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.

Frequently Asked Questions

Why convert IMA to PAF?

IMA ADPCM is headerless and hard to use outside embedded systems. PAF provides a proper format with broad compatibility.

What applications open PAF files?

SOX and PARIS workstations can handle PAF files. Most are available as free downloads for major operating systems.

How is the PAF audio quality?

PAF provides good quality at standard settings. The output clarity depends on the original IMA recording quality.

How fast is the conversion?

Processing is fast — IMA files are lightweight and PAF encoding completes in seconds on our server hardware.

Are my files kept private?

Uploaded IMA files are deleted immediately after conversion. PAF results are automatically erased from our servers within 24 hours.
