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.

SMP is the native file format of SampleVision, a sample editing application developed by Turtle Beach Systems around 1990. SampleVision was among the first PC-based visual sample editors, letting musicians view waveforms on screen and perform cut, copy, paste, and loop-point editing — capabilities previously limited to expensive dedicated hardware samplers. The SMP format stores 16-bit mono PCM audio along with sampling-specific metadata: loop start and end points, sustain loops, release loops, and MIDI root note assignments. This made SMP files directly useful for creating and exchanging patches between hardware samplers via MIDI Sample Dump Standard (SDS) transfers, which SampleVision automated through its interface. A primary advantage was bridging the PC world with professional sampling hardware from Akai, E-mu, Ensoniq, and Roland — devices that had tiny screens and minimal editing tools. The format also supported common sample rates (22050, 44100 Hz) and brief text descriptions alongside audio data. Though Turtle Beach pivoted to gaming peripherals and SampleVision was discontinued, SMP files persist in vintage sample library archives and can be converted using SoX.

Frequently Asked Questions

Why convert CAF to SMP?

The CAF container is tied to macOS and iOS. Converting to SMP removes that platform dependency entirely.

Which software plays SMP?

You can play SMP using SampleVision, SoX, legacy sampler editors. It works out of the box on most systems with standard audio software.

Will I lose audio quality in the conversion?

Quality depends on the codec. If SMP uses lossy encoding, minor data loss occurs. Lossless targets preserve the original CAF audio faithfully.

Can I convert several CAF recordings at once?

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

What happens to my files after conversion?

Your original CAF is deleted as soon as conversion ends. The resulting SMP is available for download and automatically removed within 24 hours.

How long does CAF to SMP conversion take?

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