About formats

MOV is a multimedia container format developed by Apple Inc. and introduced in December 1991 with the launch of the QuickTime multimedia framework. As the native format of QuickTime, MOV pioneered many concepts that later influenced the ISO base media file format (MPEG-4 Part 12) and its derivatives, including MP4. The container uses a hierarchical atom (or box) structure where each atom holds specific types of data — from video and audio tracks to metadata, text, and timecode information. MOV supports an extremely broad range of codecs including H.264, HEVC, ProRes, Apple Intermediate Codec, AAC, and PCM, among many others. This codec flexibility, combined with features like multiple track support, reference movies, and edit lists, has made MOV a staple of professional video production. The ProRes codec from Apple, commonly delivered in MOV containers, is an industry standard for post-production and broadcast finishing. The format handles both compressed delivery-quality content and high-bit-rate production-quality footage with equal capability. Precise timecode and metadata handling make MOV particularly valued in workflows requiring frame-accurate editing and reliable exchange between production tools. MOV is natively supported across all Apple platforms and widely recognized by professional editing software on all operating systems, maintaining its relevance across decades of evolving video technology.

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 MOV to SND?

SND is a classic audio format from the early MS-DOS era. Convert for retro computing compatibility, legacy system support, or historical audio archiving.

What programs open SND files?

SoX, Audacity, and retro computing emulators handle SND files. Some classic Mac and NeXT applications also used variants of the SND format.

Is SND the same as AU?

They are related — SND and AU share similar structures on Sun/NeXT systems. The MS-DOS variant is simpler, with a basic header and raw audio data.

What quality does SND offer?

Quality depends on the encoding parameters chosen. SND supports various sample rates and bit depths, though it was typically used at modest quality levels.

Is SND still used anywhere?

SND is primarily a legacy format. It appears in retro computing, vintage software preservation, and systems that require simple, headerless audio files.
