Settings

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.

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.

voc

VOC (Creative Voice) is a digital audio container developed by Creative Technology and introduced alongside the original Sound Blaster card in 1989. It served as the native audio format for the Sound Blaster family during the DOS era, when Creative's hardware dominated PC audio. VOC files are block-based: each file consists of typed data blocks that can carry 8-bit unsigned PCM, 4-bit and 2.6-bit Creative ADPCM, 16-bit signed PCM, as well as A-law and mu-law encoded audio. This block structure also supports silence intervals, repeat loops, and marker points, giving game developers fine-grained control over sound playback. A notable advantage was hardware-level decoding — Sound Blaster cards could play VOC data directly via DMA transfer, freeing the CPU for other tasks in an era when processor cycles were precious. The format saw extensive use in DOS games from id Software, Sierra, and LucasArts. With the rise of Windows and the WAV format, VOC gradually fell out of mainstream use, yet it remains important for retro gaming preservation and for anyone working with vintage PC audio archives.

Frequently Asked Questions

Why convert W64 to VOC?

The Wave64 format is overkill for most listeners. VOC delivers your audio in a format anyone can open instantly.

What opens VOC audio?

Use Audacity, SoX, GoldWave, older Sound Blaster utilities to play or edit VOC recordings. These tools offer reliable compatibility with the format.

Will I lose audio quality in the conversion?

Quality depends on the codec. If VOC uses lossy encoding, minor data loss occurs. Lossless targets preserve the original W64 audio faithfully.

How many W64 files can I convert in one go?

Upload as many W64 files as you need and convert them to VOC simultaneously. The batch feature handles multiple files efficiently.

Is the W64 to VOC conversion secure?

Completely. Your W64 files are erased immediately after processing, and converted VOC results are purged from our servers within 24 hours.

Do I need to install anything?

No installation needed. The W64 to VOC converter is fully browser-based — open the page, upload your audio, and download the result.
