About formats

CAF (Core Audio Format) is a flexible audio container developed by Apple and introduced with Mac OS X 10.4 Tiger in 2005. Built to overcome limitations of older formats, CAF eliminates the 4 GB file size ceiling that constrains WAV and AIFF, theoretically supporting unlimited length. The container accommodates virtually any codec — AAC, ALAC, MP3, linear PCM, IMA ADPCM, and more — within a unified wrapper. Its chunk-based architecture stores audio alongside rich metadata including channel layouts, marker regions, annotations, and MIDI data. A defining advantage is handling extremely long recordings: broadcasters and field recordists can capture hours of continuous audio without size boundaries. Flexible codec support is another strength, as one container works whether the content is high-resolution 24-bit/192 kHz lossless audio or compressed speech. Apple's Core Audio framework provides native support on macOS and iOS, ensuring low-latency playback in professional applications like Logic Pro and Final Cut Pro. For Apple ecosystem workflows requiring both versatility and scale, CAF is an exceptionally capable choice.

PVF (Portable Voice Format) is a simple audio file format designed for voice message storage in Linux-based telephony systems, most notably ISDN4Linux and its vbox voicemail application. The format emerged from the European ISDN ecosystem of the late 1990s, when Linux servers increasingly handled PBX and answering machine duties over digital phone lines. PVF files store raw signed 16-bit PCM samples at 8000 Hz mono, preceded by a minimal plain-text header specifying data format and byte ordering. This deliberate simplicity is one of the format's primary strengths — with no compression and a human-readable header, PVF files are trivially easy to parse, pipe, and manipulate using standard Unix tools. The 8 kHz rate matches the Nyquist requirement for telephone-bandwidth speech (300-3400 Hz), making PVF a natural intermediate format for voice processing pipelines. Another advantage is cross-architecture portability: the explicit byte-order declaration means PVF files move between big-endian and little-endian systems without ambiguity. The SoX audio toolkit provides native PVF read/write support, enabling straightforward conversion to modern formats.

Frequently Asked Questions

Why convert CAF to PVF?

While CAF handles large recordings well, it lacks cross-platform support. PVF opens your audio to a wider audience.

Which software plays PVF?

Use SoX, Audacity, specialized audio tools to play or edit PVF recordings. These tools offer reliable compatibility with the format.

Does converting CAF to PVF 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 CAF recordings at once?

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

Are my CAF uploads kept private?

Yes. Uploaded CAF files are deleted right after conversion, and the PVF output is removed from our servers within 24 hours automatically.

How long does CAF to PVF conversion take?

Most CAF files convert to PVF within seconds. Larger recordings may take a bit longer, but our cloud servers process audio quickly.
