About formats

W64 (Wave64) is a 64-bit audio container originally designed by Sonic Foundry — creators of Sound Forge — and later maintained by Sony after acquiring Sonic Foundry's desktop software division in 2003. The format directly addresses the 4 GB file-size ceiling imposed by Microsoft's 32-bit RIFF/WAV specification, a limitation that becomes problematic during long recording sessions, multi-channel captures, or high-sample-rate productions. W64 achieves this by extending chunk identifiers and size fields to 64 bits, using GUIDs instead of four-character codes. This structural change permits files to reach sizes measured in exabytes, effectively removing any practical storage constraint. The format supports arbitrary sample rates, bit depths, and channel configurations, making it well suited for film scoring, live concert recording, and scientific data acquisition. Sound Forge, Audacity, and other professional digital audio workstations provide native W64 support for seamless import and export. For engineers and producers who routinely work with long-form, high-fidelity material, W64 offers the reliability and simplicity of WAV without the frustrating size restriction.

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.

Frequently Asked Questions

Why convert W64 to FAP?

W64 was built for professional post-production needs. Converting to FAP makes your audio portable and easy to share.

How do I open a FAP recording?

Use Ensoniq PARIS, SoX, specialized DAW tools to play or edit FAP recordings. These tools offer reliable compatibility with the format.

Does converting W64 to FAP affect quality?

Lossless-to-lossless conversions preserve all audio data. When the target uses lossy compression, some quality reduction is inherent in the codec.

Can I convert several W64 recordings at once?

Yes — upload multiple W64 files simultaneously and convert them all to FAP in a single batch. No need to process one at a time.

Is the W64 to FAP conversion secure?

Completely. Your W64 files are erased immediately after processing, and converted FAP results are purged from our servers within 24 hours.
