In a preferred embodiment, preprocessing of a waveform is used to create exception conditions and to perform "peak packing" to shift portions of the waveform that would otherwise become clipped, so that the waveform peaks reside in a shifted position within the digital representation. Analogously, ...
Digital audio is a representation of sound, recorded or converted into a string of binary digits – or bits – that can be stored, processed, and played back on a computer. During the analog to digital conversion process, the amplitude of an analog sound wave is captured at a specified int...
A microcomputer system for converting an analog input signal, such as an audio signal representative of sound into a digital form for storing in digital form in a highly condensed code and for reconstructing the analog signal from the coded digital form is disclosed. The system includes reductive...
For example, to create an accurate digital representation of 10 kHz, you would need to use a minimum 20 kHz sampling rate. When the audio CD standard was developed this was one consideration in determining the standard sampling rate to be used. Based on the Nyquist theorem, a sampling rate...
aTo work with music in digital-audio form rather than in a symbolic representation such as MIDI, some low-level digital signal processing (DSP) is required to transform the raw audio into a form that is useful for tonality estimation 要与音乐一起使用以数字式音频形式而不是在一个象徴例如密地...
Thus, ways to automatically process and handle the growing size of private and commercial collections become increasingly important; along goes a need to make music interpretable by computers. The most obvious representation of audio files is their sound - there are, however, more ways of ...

Sample rate is the number of samples of a sound that are taken per second to represent the event digitally. The more samples taken per second, the more accurate the digital representation of the sound can be. For example, the current sample rate for CD-quality audio is 44,100 samples per...
Digital Signal Processing (DSP) is the manipulation of real-world signals within a digital computer, using mathematical techniques to enhance, change, or display the data in a specific way. It involves converting analog signals (such as audio or video) into digital form and performing various ope...
