About formats

MP2 (MPEG-1 Audio Layer II), also known by its original project name MUSICAM, is a perceptual audio codec standardized as part of ISO/IEC 11172-3 in 1993. While its successor MP3 captured the consumer spotlight, MP2 carved out a durable niche in professional broadcasting that it holds to this day. The codec splits audio into 32 sub-bands via a polyphase filter bank, applies a psychoacoustic model to determine masking thresholds, then quantizes and Huffman-codes each sub-band accordingly. Typical broadcast deployments use 192-384 kbps for stereo, yielding transparent quality with lower encoder complexity and better error resilience than Layer III. These properties explain why DVB television, DAB digital radio, and the HDV camcorder standard all mandate or prefer MP2. Encoder latency is shorter too, an important trait for live broadcasting where lip-sync matters. Three advantages keep MP2 relevant decades after standardization: graceful degradation under transmission errors vital for over-the-air signals, minimal encoding delay that suits real-time broadcast chains, and entrenched regulatory acceptance across European and Asian broadcast frameworks.
Initial release: 1993
CVS is a telephony audio encoding based on Continuously Variable Slope Delta modulation, representing voice through a 1-bit delta scheme where step size adapts to track input amplitude. Developed within CCITT (now ITU-T) standards during the 1970s, CVS encodes by comparing each sample to the previous one and outputting a single bit — up or down — with slope magnitude adjusting based on recent bit patterns. This yields extremely low bit rates, typically 16 kbps at 8 kHz sampling, efficient for narrowband voice over constrained channels. CVS files store signed delta-encoded data and are commonly processed using tools like SoX. A significant advantage is bandwidth economy: the 1-bit-per-sample approach demands minimal transmission capacity, essential for military radio links and early digital telephone infrastructure. The adaptive slope mechanism also prevents overload distortion on rapidly changing signals while keeping granular noise acceptable during quiet passages. Though modern wideband codecs have superseded CVS, it retains historical importance and niche utility in legacy telephony and embedded communication devices.

Frequently Asked Questions

Why convert MP2 to CVS?

MP2 is a broadcast-era audio codec still used in DAB/DVB radio but rarely by consumer devices. CVS conversion reformats the audio for voice-focused applications like VoIP and IVR systems.

What programs can open CVS?

CVS is supported by SoX, telephony applications, and CVSD-compatible voice processing tools.

What happens to audio quality during conversion?

CVS has format-specific limitations. The converter decodes your MP2 and re-encodes within CVS capabilities — results vary by format.

Is batch conversion supported?

Absolutely. Drop multiple MP2 files into the converter and they will all be processed to CVS together in one operation.

Are my conversions secure?

All uploads happen over encrypted connections. Your MP2 is deleted after conversion, and CVS results are cleared within 24 hours.

What platforms are supported?

Any device with a modern browser — Windows, macOS, Linux, Android, iOS. Convert MP2 to CVS from wherever you are.
