High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.
In the end Sony won, so 16 bits and 44.1 kilosamples per second prevailed. Philips found a way to produce 16-bit quality using its 14-bit DAC by using four times oversampling. [17] Some early CDs were mastered with pre-emphasis, an artificial boost of high audio frequencies. The pre-emphasis improves the apparent signal-to-noise ratio by making ...

It is commonly used to describe compressed data bitrates. For example, the transparency threshold for MP3 to linear PCM audio is said to be between 175 and 245 kbit/s, at 44.1 kHz, when encoded as VBR MP3 (corresponding to the -V3 and -V0 settings of the highly popular LAME MP3 encoder). [1]

Encoding is limited to constant bit rate (CBR) and up to 20 kbit/s. The first and only version of the codec is WMA 9 Voice. Windows Mobile-powered devices with Windows Media Player 10 Mobile have native support for WMA 9 Voice playback. [30] In addition, BBC World Service has employed WMA Voice for its Internet radio streaming service. [49]
The n.nnn quality parameter (-V) is documented at lame.sourceforge.net but is only supported in LAME with the new style VBR variable bit rate quality selector—not average bit rate (ABR). A sample rate of 44.1 kHz is commonly used for music reproduction because this is also used for CD audio , the main source used for creating MP3 files.
fre:ac is a free audio converter and CD extractor for Windows, Linux, macOS, and FreeBSD, distributed under the GPL-2.0-or-later. [2]Besides extracting audio from compact discs (with various features including hidden track detection), fre:ac can also convert audio files from one format to another or to the same format at a lower bitrate (a higher bitrate can be forced but this does not ...
