About formats

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.
Initial release: 1989
CDDA (Compact Disc Digital Audio), known as the Red Book standard, defines audio stored on music CDs. Jointly developed by Sony and Philips and published in 1980, it established parameters that shaped digital audio for decades: 16-bit linear PCM at 44.1 kHz stereo, yielding 1,411.2 kbps uncompressed. Each disc holds up to 80 minutes organized into tracks with index points, sub-channel data for text display, and error correction codes (CIRC) ensuring reliable playback despite minor scratches. When audio is ripped from a CD, the resulting stream is often saved with the .cdda extension as raw PCM before conversion. The most obvious advantage is uncompressed, lossless nature — what reaches your ears is mathematically identical to the studio master at the specified resolution. Robust error correction provides excellent resilience, maintaining audio integrity even when disc surfaces suffer moderate wear. Having sold billions of units since the first commercial release in 1982, CDDA established baseline quality expectations for digital music and remains the reference against which compressed codecs are measured.

Frequently Asked Questions

Why convert VOC to CDDA?

CDDA (Red Book) is the standard for audio CDs — 16-bit, 44.1 kHz stereo PCM. Converting VOC produces tracks ready for disc burning.

What can open CDDA files?

CD burning software (Nero, ImgBurn, K3b) and any audio CD player accept CDDA data. Most DAWs import CDDA-format audio directly.

What exactly is CDDA?

CDDA stands for Compact Disc Digital Audio — the Red Book standard. 16-bit, 44.1 kHz stereo PCM used on every audio CD.

Can I burn the output directly?

The CDDA output is in the correct PCM format for audio CDs. Import it into your disc burning software and write to a blank CD.

Will mono VOC become stereo?

The converter can produce stereo CDDA from mono sources, but both channels carry identical audio — true stereo requires a stereo source.
