About formats

DVMS (Dutch Voice Messaging System) is a telephony-grade audio encoding born from the Netherlands' early push toward digital voicemail infrastructure. Deployed through KPN (formerly PTT Telecom) in the mid-1980s, the format stores mono voice data at a narrow 8 kHz sample rate, prioritizing compact message size over sonic breadth. Audio is compressed with a proprietary variant of logarithmic companding similar to European A-law encoding, squeezing recordings to roughly 8 kbit/s while keeping speech intelligible. Each file carries a small header identifying sample rate, compression type, and message metadata, which made automated routing across early PBX and voicemail systems straightforward. Although DVMS never gained traction outside Dutch telecom circles, it influenced how European carriers designed later voice messaging protocols. Tools like SoX and several legacy telephony libraries still read and write DVMS files, allowing archival playback of decades-old messages. Among its practical advantages: extremely small file sizes (a one-minute message occupies roughly 60 KB), reliable speech clarity despite aggressive compression, and a simple container layout that is easy to parse programmatically.

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.
