Raw Audio

SNDR stores headerless audio data — extracting from MPEG-2 produces raw samples for specialized tools.

Fast Extraction

Audio extraction skips video processing — your MPEG-2-to-SNDR conversion finishes in seconds, not minutes.

Secure Files

MPEG-2 uploads are erased immediately after conversion. SNDR outputs are deleted within 24 hours.

About formats

MPEG-2 is a widely deployed video and audio compression standard developed by the Moving Picture Experts Group and approved in 1995 as ISO/IEC 13818. Building on the foundations of MPEG-1, MPEG-2 was designed to handle higher bit rates and resolutions, particularly interlaced video for broadcast television, making it suitable for applications ranging from standard-definition TV to high-definition content. The standard introduces the concept of profiles and levels, allowing implementations to target specific capability tiers — from the Simple Profile for basic applications to the High Profile supporting 4:2:2 chroma for professional broadcast. MPEG-2 became the compression backbone of digital television worldwide, adopted by DVB, ATSC, and ISDB standards, and it serves as the video codec for DVD-Video, bringing movie-quality video to the consumer market. The transport stream layer provides robust multiplexing with error resilience features essential for broadcast delivery over noisy channels, while the program stream variant serves storage-oriented applications like DVDs. MPEG-2 supports resolutions up to 1920x1152 in the Main Profile at High Level, with bit rates reaching 80 Mbps in professional configurations. Although newer codecs like H.264 and HEVC offer substantially better compression efficiency, MPEG-2 remains entrenched in broadcast infrastructure, cable and satellite systems, and billions of DVD discs in circulation worldwide.

SNDR is the audio file format produced by Sounder, an early MS-DOS sound recording and playback utility from the early 1990s. Before Windows brought multimedia to the mainstream, Sounder was among a handful of DOS programs that let PC users capture and play audio through rudimentary hardware — often the PC speaker itself or early 8-bit sound cards. The format stores 8-bit unsigned PCM samples without any file header, relying on application defaults to determine playback parameters. Sample rates were typically low (4000 to 11025 Hz), reflecting hardware limits and storage costs when a 20 MB hard drive was considered generous. One practical advantage was absolute minimalism — with zero overhead bytes, every bit of the file was audio data, which mattered when storage was measured in kilobytes. The format could be piped directly to sound hardware without parsing, making real-time playback feasible on slow processors. Despite its simplicity, SNDR holds a place in computing history as one of the formats that brought digital audio to ordinary PCs. Files from this era occasionally surface in retrocomputing archives. SoX and ffmpeg can interpret SNDR files given the correct parameters, enabling preservation of early digital audio recordings.

Frequently Asked Questions

Why convert MPEG-2 to SNDR?

SNDR is a headerless audio format for legacy SoundRunner applications.

How do I open SNDR files?

SoX and raw audio editors can process SNDR data.

Is only the audio extracted?

Yes — the video portion of the MPEG-2 file is discarded. Only the audio track is saved as SNDR.

Can I convert multiple files?

Upload several MPEG-2 videos at once and extract SNDR audio from each simultaneously in a single batch.

Are my uploads secure?

MPEG-2 files are deleted immediately after conversion. SNDR outputs are removed from our servers within 24 hours.
