The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

mpeg-2

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.

w64

W64 (Wave64) is a 64-bit audio container originally designed by Sonic Foundry — creators of Sound Forge — and later maintained by Sony after acquiring Sonic Foundry's desktop software division in 2003. The format directly addresses the 4 GB file-size ceiling imposed by Microsoft's 32-bit RIFF/WAV specification, a limitation that becomes problematic during long recording sessions, multi-channel captures, or high-sample-rate productions. W64 achieves this by extending chunk identifiers and size fields to 64 bits, using GUIDs instead of four-character codes. This structural change permits files to reach sizes measured in exabytes, effectively removing any practical storage constraint. The format supports arbitrary sample rates, bit depths, and channel configurations, making it well suited for film scoring, live concert recording, and scientific data acquisition. Sound Forge, Audacity, and other professional digital audio workstations provide native W64 support for seamless import and export. For engineers and producers who routinely work with long-form, high-fidelity material, W64 offers the reliability and simplicity of WAV without the frustrating size restriction.

Beyond WAV Limits

W64 removes the 4 GB cap of standard WAV — ideal for extracting audio from long MPEG-2 recordings.

Fast Extraction

Audio extraction skips video processing — your MPEG-2-to-W64 conversion finishes in seconds, not minutes.

Secure Files

MPEG-2 uploads are erased immediately after conversion. W64 outputs are deleted within 24 hours.

Frequently Asked Questions

Why convert MPEG-2 to W64?

W64 extends WAV past the 4 GB limit — essential for long uncompressed recordings.

How do I open W64 files?

Sound Forge, Audacity, Reaper, and VLC handle W64.

Is only the audio extracted?

Yes — the video portion of the MPEG-2 file is discarded. Only the audio track is saved as W64.

Can I convert multiple files?

Upload several MPEG-2 videos at once and extract W64 audio from each simultaneously in a single batch.

Are my uploads secure?

MPEG-2 files are deleted immediately after conversion. W64 outputs are removed from our servers within 24 hours.
