About formats

APE is the file format of Monkey's Audio, a lossless compression algorithm created by Matt Ashland around 2000. The codec achieves some of the highest compression ratios among lossless encoders — typically reducing CD-quality audio to 50-60% of its original size, with an insane preset pushing further at the cost of speed. Every bit of the original waveform is preserved and perfectly reconstructable. The engine uses adaptive prediction filters and range coding to exploit redundancies in PCM audio, with multiple compression levels letting users balance processing time against file size. A standout advantage is superior compression density: tests frequently show APE files 2-5% smaller than equivalent FLAC or WavPack encodings. The format bundles robust tagging through APEv2 metadata, supporting album art, lyrics, and extensive catalog information. While platform support is narrower than FLAC — playback requires software like foobar2000 or VLC — audiophiles who prioritize storage efficiency without quality compromise continue to favor APE as their archival format of choice.
Initial release: 2000
SND is a multi-platform audio file extension used across several computing ecosystems since the late 1980s. On Sun and NeXT workstations, .snd files follow the AU format structure — a header with magic number 0x2e736e64, data offset, encoding type, sample rate, and channel count, followed by raw audio. On MS-DOS PCs, the same .snd extension was used by early sound utilities like Sounder and SoundTool for simple 8-bit unsigned PCM recordings. Macintosh systems also employed .snd for sound resources embedded in the resource fork. Because the extension is shared across incompatible formats, audio processing tools typically inspect the file header to determine which variant they are handling: files beginning with the AU magic number are treated as Sun/NeXT audio, while headerless files are interpreted as raw PCM with assumed parameters. The Sun/NeXT variant supports multiple encodings including mu-law, A-law, 8-bit and 16-bit linear PCM, and ADPCM, making it versatile for both speech and general audio. One advantage of the AU-style SND is its self-describing header, which enables any compliant player to determine sample format and rate without external metadata. The MS-DOS SND variants hold historical value as artifacts of the era when Sound Blaster cards first brought digital audio to personal computers. SND files from all platforms can be processed and converted using SoX and other audio tools.

Frequently Asked Questions

Why convert APE to SND?

SND is a basic audio container used by Unix and NeXT systems. Converting from APE provides raw audio data compatible with these environments.

What is the SND format?

SND is closely related to AU and stores PCM or compressed audio. It originated on NeXT/Sun platforms and remains common in Unix toolchains.

What opens SND files?

SoX, Audacity, and most Unix audio utilities handle SND natively. It is also recognized by macOS built-in audio frameworks.

Is quality preserved?

When using PCM encoding, SND preserves all audio data from the lossless APE source without any degradation.

Can I batch process files?

Yes — upload multiple APE files and convert them all to SND in parallel. No repeated manual steps required.

Is my data secure?

APE uploads are deleted immediately after processing. SND files are removed from our servers within 24 hours.
