SND (.snd)
.snd file signature | audio/basic
SND is a legacy audio file format originally associated with Sun Microsystems and NeXT, and it is now supported by many audio tools and operating systems. It was used for storing simple digital audio, including voice recordings, sound effects, and early multimedia content, and is commonly encountered in older Unix-based systems. The format is generally safe, but because it is obsolete, some modern applications may have limited support or require conversion.

Frequently Asked Questions
What is a .snd file?
A .snd file is identified by the magic bytes 2E 73 6E 64 at byte offset 0. SND is a legacy audio file format originally associated with Sun Microsystems and NeXT, and it is now supported by many audio tools and operating systems. It was used for storing simple digital audio, including voice recordings, sound effects, and early multimedia content, and is commonly encountered in older Unix-based systems. The format is generally safe, but because it is obsolete, some modern applications may have limited support or require conversion.
What are the magic bytes for .snd files?
The magic bytes for SND files are 2E 73 6E 64 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .snd file?
To validate a .snd file, read the first bytes of the file and compare them against the known magic bytes (2E 73 6E 64) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .snd files?
The primary MIME type for .snd files is audio/basic.
Is it safe to open .snd files?
SND (.snd) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
