About formats

RealAudio is a proprietary audio format developed by RealNetworks and first released in 1995 as one of the earliest technologies enabling real-time audio streaming over the internet. During the dial-up era, RealAudio was genuinely revolutionary — it let users listen to audio as it downloaded rather than waiting for the entire file, a paradigm shift when a three-minute song could take 30 minutes to transfer. The format evolved through multiple codec generations: early versions used low-bitrate speech codecs for 14.4 kbps modems, while later iterations (RealAudio 10, built on AAC) delivered near-CD quality. RA files support constant and variable bitrate encoding, adaptive multi-bitrate streaming, and buffering algorithms designed to minimize playback interruptions on unreliable connections. At its peak, RealPlayer was installed on hundreds of millions of PCs, and broadcasters like the BBC and NPR relied on RealAudio for online streams. A lasting technical contribution was the adaptive bitrate streaming concept that influenced later standards like HLS and DASH. Though supplanted by modern codecs, vast archives of RA content from early web radio still exist and need conversion for playback on current devices.

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 RA to SND?

Since RealNetworks' RA format has fallen out of use, converting to SND preserves your recordings in a viable format.

How do I open a SND recording?

SND can be opened with Audacity, SoX, various audio utilities. Most modern audio applications handle this format without issues.

Does converting RA to SND 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 RA recordings at once?

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

Are my RA uploads kept private?

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

How long does RA to SND conversion take?

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