Therefore, 16-bit digital audio found on CDs has a theoretical maximum SNR of 98 dB, and professional 24-bit digital audio tops out as 146 dB. As of 2011 [update] , digital audio converter technology is limited to an SNR of about 123 dB [ 12 ] [ 13 ] [ 14 ] ( effectively 21 bits) because of real-world limitations in integrated circuit design.

It can decode signals many decibels below the noise floor in a 2500 Hz band (note that SNR in a 2500 Hz band is approximately 28 dB lower than SNR in a 4 Hz band, which is closer to the channel bandwidth of an individual JT65 tone), and can often allow amateurs to successfully exchange contact information without signals being audible to the ...

Diamond Cut Audio Restoration Tools (DC-Art) was originally a private venture by R&D engineer Craig Maier and software engineer Rick Carlson. Developed in the early 1990s, the original concept was conceived in an attempt to preserve the extensive Edison Lateral collection of test pressing recordings held at the Edison National Historic Site in West Orange, New Jersey.
G.711.1 allows a series of enhancement layers on top of a raw G.711 core stream (Layer 0): Layer 1 codes 16-bit audio in the same 4kHz narrowband, and Layer 2 allows 8kHz wideband using MDCT; each uses a fixed 16 kbps in addition to the 64 kbps core. They may be used together or singly, and each encodes the differences from the previous layer.
KMixer is the Kernel Audio Mixer driver, a part of WDM Audio in Windows 98 to Windows XP which handles the mixing of multiple sound buffers into an output. The tasks performed by KMixer.sys: Mixing multiple PCM audio streams; Format, bit-depth (also known as word-length) and sample-rate conversion; Speaker configuration and channel mapping
