CDDA to CVS Converter
Convert CD audio to CVS continuously variable slope
Telephony Encoding
Encode CDDA audio as CVS — the delta modulation format used in secure telephony and military voice communication systems.
Compact Output
CVS produces very small files from CDDA source. Delta encoding compresses voice data aggressively for bandwidth-limited channels.
Server Processing
CVSD encoding runs on our infrastructure. No specialized telephony tools or signal processing software needed on your machine.
How to convert CDDA to CVS
Select files from Computer, Google Drive, Dropbox, URL or by dragging it on the page.
Choose cvs or any other format you need as a result (more than 200 formats supported)
Let the file convert and you can download your cvs file right afterwards

Frequently Asked Questions
CVS uses CVSD encoding for telephony and military communications. Converting from CDDA provides clean source material for these applications.
Continuously Variable Slope Delta modulation is a compact voice encoding used in secure communications and certain telephony systems.
No — CVSD is designed for speech only. Music will sound significantly degraded due to the narrow bandwidth and delta modulation approach.
Military radio systems, certain VoIP implementations, and telephony equipment that rely on CVSD encoding for voice compression.
Upload multiple CDDA tracks and batch-convert to CVS — handy for preparing voice content for CVSD-based communication systems.
